Donald S Clem III

If I could give 10 stars I would. Dr. Yen is the best of the BEST! I am not a fan of dentists and have suffered through many bad experiences that made me shy away from taking care of my teeth for years. I had a major problem with a tooth and was referred to Dr. Yen by my regular dentist, Dr. Steven Myers (also amazing!). From the first day, I knew I was in great hands.

The teamwork and compassion of the office staff is second to none. And, as for Dr. Yen, he really knows his stuff and he will take the time to explain it to you so you can understand. His patient, kind and caring manner will set the most nervous of people (me!) at ease. He is a man of integrity and stands behind his work, seeking nothing short of perfection.

I have now moved 500 miles away, but if I need any further periodontal work, the only dentist I will see is Dr. Yen. Have no doubt that you will be in the best of hands with Dr. Yen and his incredible staff.

Dr. Yen is the consummate professional. I am in the process of having all my teeth restored after cancer n yrs of chemotherapy which destroyed the enamel on my teeth. I was referred to Dr. Yen by my superb primary dentist Dr. Nishimura for a problem involving a back molar. n crown lengthening. Dr. Yen performed a consultation on the issue n what options I had to resolve this problem.

I felt so confident in his knowledge n expertise that I let him make the final decision. my care has been expertly coordinated by 3 outstanding dental craftsman's Dr. Yen. Dr. Nishimura an Dr. Curtis. what a fantastic team! I'm half way through my journey. n couldn't b happier with the results so far. Dr. Yen n his team are dedicated professionals n making the most positive outcome no matter what the situation or challenge. I am forever grateful n thankful for the whole team taking on my case with positive happy results. I highly recommend their dental services. u won't b disappointed

After an absolutely horrifying and uncomfortable experience at a dentist in Huntington Beach, I was redirected to Dr. Yen's office located among other offices within the St. Jude Heritage group. Thankfully, I was able to get an appointment, which believe me, is not easy. Dr. Yen and ALL of his staff are amazing, I can't say enough positive things about them. I'm an individual who is deathly afraid of the dentist (no exaggeration!) which is why I was in desperate need in the first place (100% my own fault).

Everyone treated me with kid gloves which I greatly appreciated. To my complete and utter surprise, my appointments over the past year were pretty much painless and I am super grateful for these gentle professionals. All of my procedures are now complete and now I just go for regular cleanings. I am so proud of myself for being brave enough to make my first appointment, it's seriously the best decision I ever made.

This office is incredibly busy and frequently booked up, so again, I'm not going to say that it's easy to get an appointment here, but that should tell you how incredibly reputable and successful this practice is. So I recommend to keep pushing and try your hardest to get an appointment here especially if you are in dire straights. An enormous ***THANK YOU*** to Dr. Yen and his staff of professionals who got me through all the fear, anxiety, and enormous stress. They all deserve 10 stars! ***Highly recommended.*** Now to get over my fear of heights, stay tuned! LOL

I have been going to Dr. Donald Clem for 10+ years now and he is truly amazing. His periodontal office is top-notch - very clean with the most advanced equipment/technology and the entire team is terrific. I've had multiple procedures, regular cleanings/maintenance and would highly recommend Dr. Donald Clem to everyone for all your periodontal health needs. He is the very best!

L have nothing but positive things to say about Dr. Donald Clem and his staff. I have been a patient for over five years and have been extremely pleased with the professionalism, quality of work, and genuine care from the team. I really enjoy having Stephanie clean and maintain my teeth. She is upbeat, personable, and really cares about her patients and what she does. A true professional who represents herself and the company well.

Dr Clem provided a great service. I'm very satisfied with the result. If you get an estimate make sure that the office staff gets a pre-authorization from your insurance company prior to the procedure to make sure the cost of the service is in line with the estimate provided. I had an issue with this.

Thank you to Dr Yen and the entire crew for doing such an amazing job from start to finish. I am super happy with Dr Yen approach, he strives to make sure things come out with the best results. I was struggling for a long time w a sharp pain in my tooth and I wanted to make sure I chose the best Dr. I am super happy w my choice. Highly recommend Dr Yen to anyone needing an awesome oral surgeon. He also makes himself available after procedure for any questions. Thank you again Dr Yen =

Dr Yen is amazing! I had a terrible experience with an oral surgeon in Yorba Linda and had to have my implant removed. Dr Yen was so gentle, thorough and calming throughout the process. His office is immaculate and his staff is awesome. I barely felt the injections to numb my mouth which is always a blessing. When he told me I was done, I was in tears. It was such a completely different experience than with the other oral surgeon in Yorba Linda! So happy I found him. If I could give him 10 stars, I would!

Absolutely horrible experience and even worse customer service. They lied about an xray price right to me and won't make it right. I highly recommend avoiding this company at all costs.

Worst company ever! Scammed me with an exam i said i didn't want and they assured it was free, then was charged $250 for it and reported it to my credit. Very dishonest company. I'll be sure to post this to my 400k followers on IG and YouTube :

Horrible experience, charged me over $250 for A consultation. Make sure to ask for prices before They overcharge you for xrays.

Dr. Yen is a good surgeon. I had severe gum recession in the lower teeth and he did a good job covering the roots. I was hoping for an aesthetically better result--i.e. a higher gum line--but I trust that was not possible. The biggest problem for me and the main reason for which I'm not going back for my upper gums is the front desk. I found them standoffish, cold, and borderline rude.

I read other reviews that are saying similar things about the people working there, especially the person in charge of finances. I fear the front desk is harming their business, and they should do something about it.

Let me first say I am not a patient of Dr. Yen. My family member is and this is based on my experience taking said family member. My grandmother is older and needs help getting to her appts. I also have a one year old who she loves to go with us places. Recently I took her to Dr. Yens and the lack of professionalism and over all kindness from the front staff is beyond me.

I would never stay in the waiting room if my son was screaming or crying. In fact I went for a walk with him once my grandma was taken back to her appt. when I went to pick her up she was laughing with the ladies at the counter about my son. Whomever the receptionist was looked at me and said " well I hope he's is up at 2 am making as much noise for you as he made in here today!" I'm sorry, what?

So incredibly rude. I was maybe in the waiting room a total of 15 minutes and that was the reaction. Overall I would recommend Dr Yen. My grandma loves him and his assistant but the front office staff needs serious work on their customer service.

Simply Amazing work I highly recommend Doctor Nelson Yen just for the amazing talent he has. The staff is simply amazing as well. Went in for for bone grafts and and posts done so far and I have absolutely 0 regrets about coming here. If you want a dental specialist who actually gives you the patient 100% then I would highly recommend Doctor Nelson Yen

At least 6 years ago, I began felt the tenderness at the gum below an old root-cannel tooth. My ex-dentist found there is an extra tooth imbedded in the close vicinity. I was told then everything was fine and just not to press the area to avoid further complications. Fast forward to February 2018, a yellow tip filled with pus popped out at the problem area.

The ex-dentist said I need an implant. My gum became visibly infected. I have to take course after course of the antibacterial medications to prevent it from spreading. By then, I have lost confidence on the dentist who I have seen for 20 years. Desperately in need of immediate help, I sincerely prayed for God's guidance. Then something wonderful happened!

I saw a Yelp reviewer mentioned her satisfying implant experience with Dr. Nelson Yen. After reading all the Yelp reviews on Dr. Yen, I decided he is the one - an experienced dental surgeon who is well respected in his field of services. At the 1st appointment, Dr. Yen ordered the full mouth X-Ray to determine the scope of bone damage. He was very generous to offer me a free 3D Scan in order to pin pointing the source of my problem. Dr. Yen is precise, detail-minded and very compassionate.

I felt very comfortable to be his patient. He was surprised that I would travel 2+ hours from Burbank to Fullerton to seeking for his help and promised to do his best to help me. My treatment started with the Bone Graft in April, then the Implant in August. All went well and healed well. It rebuilt my dental bone for the substitute tooth as well as stopped the drainage of my energy caused by the chronic infection.

I definitely feel better now than before. Thanks to Dr. Yen! On the eve of Thanksgiving, I like to express my greatest gratitude to Dr. Yen for taking care of me. Also my sincere thanks to all the Yelp reviewers as well, through your unselfish sharing, it helped me find the best help! May God Bless all. Happy Holidays!

I had gum grafting and an extraction 9 years ago by Dr Yen. I can't say enough great things about him. He's patient, caring, and really takes the time to explain and address any concerns. He was meticulous in my surgery and called me afterward to personally check in. He monitors my gum condition even now and I see the hygienists in his office 3x/year for cleanings (alternating with my regular dentist).

I recommend Dr. Yen for your periodontal needs. It's very pricey but you don't want to cut corners when it comes to your oral health care. While I give Dr Yen a full 5 star rating, his front office staff does not deliver the same friendly and warm service. In all of these years going to that office, I can't think of 1 front desk employee who has ever been genuinely warm and friendly. Thankfully most of my time is spent with his fabulous hygienists, so I will remain a happy client.

I highly recommend seeking Dr. Nelson Yen for a consultation, as not all periodontist are created the same! Dr. Nelson Yen recommended that I wait and get fillings, instead of getting extractions and implants, which was the complete opposite of what several periodontists advised in the area! A year has passed and my teeth are still intact! This alone should give you enough reason to seek Dr. Yen. I've decided to update my review and provide 'yelpers' a more in-depth explanation of my experience.

My opponent was missing his jump shots. I wanted to conserve my energy for offense, so I planted both of my feet and raised my hands while he took another 3-point jump shot. Which might have been a mistake since the basketball game had to stop abruptly as my opponent elbowed my two front teeth while coming down. I felt one my of front teeth dislocate (I popped the tooth back in place but cracked) and a quarter of the other tooth was broken off.

Not only was this a nightmare, it was 8pm on a Tuesday night which meant no one was available. The level of stress and panic set in full flight the following morning as I was sure that I needed dental implants. I scheduled 3 dentist appointments and all referred me to 3 periodontists in the area. I wanted to get work done immediately, but I just did not feel comfortable with any of them to move forward.

So I searched for another periodontist and found Dr. Nelson Yen on Yelp. He noticed my state of mind (fight or flight) and instantly helped put my mind at ease by listening to my concerns and needs. He then advised, "It may appear that I needed implants but implants were "not" necessary. Instead, I should get fillings in lieu of getting implants".

I vividly recall being shocked as the 3 previous dentists and periodontists were adamant that the only viable option was to get implants. He clearly cares for his patients and apparent that he is looking at things long-term instead of making a quick buck. (I am now a patient of his for life). Even though Dr. Yen surgically places implants, he honestly told me that they were not necessary in my situation. If and when my two front teeth have issues in the future, I plan to get my work done here and will provide another update.

Dr Yen was fantastic. I was recently referred for a gum rescission issue and was admittedly a bit hesitant as I'd heard horror stories from friends who had similar surgeries due to the pain and recovery involved. His ability to use implant tissue and surgical skill were off the charts. I had no complications and the surgery was virtually painless - to the point that the next day my wife was yelling at me for eating foods on the don't eat list as I was feeling great.

He was super attentive and reached out personally afterwards to check in on me. I'd highly recommend him. I hope I don't need more surgery - but if so I know where I'd go.

I was a patient of Dr. Nelson Yen I have nothing but positive things to say about him and him only.(not front office staff) Dr. Yen's energy is so positive, caring, calm and genuine. He is very knowledgeable, he also took his time explaining my dental situation. I wish there were more doctors like him. He actually reminded me of Dr. Peter Helton my previous dermatologist in Newport beach wonderful Doctor too! Dr. Yen's office facility is spacious, beautiful, professional and clean.

It is located in one of the nicest parts of Fullerton. His front office staff is ok, they don't stand out like Dr. Yen they don't even come near his level of kindness and professionalism. Yes I recommend Dr. Yen will go back when I need to! Thank you Dr. Nelson Yen.

There is a reason why they're so busy and the waiting room is always packed. This is one of the nicest dental offices you will ever see. It is super clean and the staff are all very friendly and helpful. My parents have had procedures done by Dr. Yen and they could not be happier with his work. I had to see Dr. Yen for a bone graft and also to pull out a wisdom tooth.

I did not feel anxious at all prior or during the procedure as he continually monitors you and talks to you to see how you are doing. He also provided an eye mask to put over your eyes which made me feel even more comfortable during the procedure. Dr. Yen is also great during follow up visits and takes the time to explain to you about what is going on. He'll also call you to see how you are doing.

If you're going to get your teeth cleaned, you should also see if you can get Kristi. She does a great job and will give you one of the most thorough cleanings you will ever receive. Nobody likes to go to the dentist. However, Dr. Yen and his wonderful staff will make your trip a lot more pleasant. I highly recommend Dr. Yen if you need some type of oral surgery.

Another failed root canal. another call to Dr YEN! He and his assistant Brandi are so caring and efficient and so good at what they do. I cannot say enough good things about Dr Yen and his team!

Dr. Yen is a gifted surgeon. I don't know how these guys do it. He is a real good guy, and I just am writing this because I appreciate the objective nature and quality of his work. I have probably been to 50 dentists. I am very fortunate to have bumped into him when I had a dental implant get infected. Thank you Dr. Yen.

If I could give Dr. Yen 100 stars, I would. You cannot find a more sincere, honest periodontist like Dr Yen. Just a great dentist with a good heart. Thank you, Dr. Yen!

I owe many thanks to Dr Nelson Yen. I had a "multi-stage" regenerative replacement of my front tooth by extensive bone grafting. Dr. Yen chose not to charge for the 2nd graft; he's a man of integrity & insured a stable platform. He outsourced the artistry for matching my unique teeth opalescence & striations. He continually consulted w/ my dentist regarding achieving superior results in forming my balanced gum line. Folks, this is an extremely professional organization; from check-in to assistant, to Dr. to Shari in scheduling.

I could go on but I'll leave you w/ this question; when was the last time your Dr. phoned you to see how you doing after a procedure. WOW - enough said! As a former satisfied patient, I will accept inquiries by phone at 714-904-6596.

Dr. Nelson Yen is a phenomenal surgeon! My dentist told me I needed to see a periodontist about my gum recession on my lower front teeth and recommended Dr Nelson Yen. During my consultation with Dr. Yen, he spent an hour talking with me about my particular case, and made sure I was completely informed and comfortable about the surgery he was recommending. Dr. Yen performed a gum graft on my four lower front teeth and the results were unbelievable!

The surgery lasted 45 minutes and I was extremely relaxed the entire time. I was awake for the entire surgery and did not feel an ounce of pain. Dr. Yen was very calming and made sure I was comfortable throughout the surgery. He is professional, welcoming, and more then anything, he genuinely cares about his patients. When I got home from the surgery, he called and gave me his personal cell phone incase I had any questions or concerns.

My recovery was was as amazing as the surgery itself; I felt very little discomfort and was able to begin regular activities within 3 days. I have had amazing feedback from friends and family about my results. Even my regular dentist and hygienist could not believe how beautiful the gum graft looked when I got my teeth cleaned. I can honestly say I have never been this happy with the way my gums look and I will continue to see Dr. Yen for any future procedures I may need. Thank you so much Dr. Yen!

If you are ever in need of any periodontal treatment Dr. Yen is the doctor to see! I was referred to Dr. Yen by my primary dentist for crown lengthening surgery in preparation for placement of new crowns. Long story short my old crowns were placed in a way that they were causing my gums to be inflamed. Being that my crowns are on my six front teeth aesthetics were a very important factor.

Not only do my gums look healthier than I can ever remember they are aesthetically perfect. I could not be happier with how everything turned out. Not only does Dr. Yen do great work, he also is wonderful on a personal level - so professional and really listens to and cares about what you have to say. I have a complicated dental history and have seen a lot of dental professionals over the years - dentists, periodontists, orthodontists, endodontists, oral surgeons etc.

I know the difference between a good doctor and a not so good one - I've seen it all. Dr. Yen is great. I will not hesitate to visit him for any periodontal issues in the future.

I have had the privilege of watching Dr. Donald Clem evolve into one of the top surgeons of our generation. He is known world wide for his innovations in periodontal medicine. In choosing Dr. Clem as your doctor and your advocate for your periodontal health, you will have made a decision that you will never regret

Dr. Yen is the best! He is super nice & professional, and you can tell that he genuinely cares about his patients. I was a bit nervous to get my procedure done, but Dr. Yen did a fantastic job and I am thrilled with the results. The office is gorgeous and luxurious, and they even give you free coffee vouchers to Peet's Coffee & Tea! Highly recommend. :
