Doctor Steven Hernandez graduated from the U.S.C. School of Dentistry in 1989. Dr. Hernandez joined Baseline Dental Practice in 1994. He enjoys cosmetic and restorative dentistry. Dr. Hernandez is an active member of the American Dental Association, California Dental Association, and Tri-County Dental Association.
At Baseline Dental Practice, we established The Smile Club and Healthy Gums Club to give each patient a year of dental coverage for a low annual payment. Imagine having a routine dental cleaning and checkup, then leaving without a bill. Or maybe you have a question about your teeth and don't want to visit the dentist because there is a fee to evaluate them.
Dr. Firouz became an Invisalign Diamond Plus Provider in 2021. To become an Invisalign Diamond Plus orthodontist, you must be in the top 1% of Invisalign Providers. A Diamond Plus status means Dr. Firouz performs more Invisalign cases than 99% of orthodontists, which is a testament to his vast experience with Invisalign for both adults and children.
Before dental implants, patients had two options to replace missing teeth: a bridge or a denture. Implants have almost entirely replaced the need for dental bridges, and now implants can stabilize dentures and provide a more secure fit. We no longer need to drill on healthy teeth to make a dental bridge.

Best Dental Practice. I have been going here since I was born and I am now in my 40's. The front staff is awesome and make sure I never get surprise bills. The hygienists plenty of time cleaning my teeth and I never feel like it was just a quick bang-up job. The doctors are thorough and considerate of everything and the assistants as well. You guys are the best and I will likely be coming back for another 40 years. if I live that long.

So, I've been going to Baseline Dental Practice since I was in my teens. I'm 39 now, married with kids. I've been going to Dr. Hernandez for what feels like FOREVER. I've had a ton of work done (yeah, didn't take the best care of my teeth when I had braces) and he's always been very kind, professional and understanding.

Not to mention that it takes A TON of Novocain to numb me - stuff wears off in like 20 min so he's usually gotta block the nerves in half my mouth. He's always accommodating and if I need more - I get it, no prob. Staff is wonderful as well. And I promised Theresa I'd write this review! I highly recommend the Baseline Dental crew.

This is a well-established family-feel practice. They get to know you and make you feel so welcomed and a part of their community. They are always focused on the best interest of the patient-transparent, cost-saving oriented, and supportive. I highly recommend BDP. I've been with them a long time, and always go back even when I have moved. They are a kind group of humans who do great work!

This has been our new dental office for the last 6 years. We just started taking 2 of our kids here that are older. The transition went well. Everyone has always been very friendly and professional. We have all our needs met and feel any questions we have are answered. They are very honest and only recommend work that is needed. We had a very bad experience at our previous dentist who was asking for us to do work that was not necessary and then kept charging us and when we'd call they had nothing on file.

It was a breath of fresh air to come to an office with integrity and someone you could trust. Thank you to all the staff. The ladies im front are always very kind and accommodating.

I highly recommend this dentist practice! I've been coming for years, the staff to the cleaning is excellent! If you hate going to the dentist like I do, this place will make you feel comfortable and safe. They treat you so well and let me tell you the cleaning is the best, I got Brittany today and she did such a great job! Thank you Baseline Dental.

Remarkably rude on the phone. When I informed them I have BCBS but wouldn't be using my insurance and that paying in full wouldn't be an issue, the woman became extremely dismissive. Refused to do exam + x ray + cleaning in one visit, requesting I come back twice. When I informed her that I am far too busy to make repeat trips to the dentist for something that I have always had done in one sitting at every other dentists office over the past 20+ years she said "goodbye" and hung up. Seems like a standard low rent CA dental practice designed to run up billing on insurance.

I've had miserable experiences with several dentists over the years. I've twice before had unsuccessful extractions and the doctors quit mid procedure due to the difficulty. This left me with a painful situation and a lot of trauma. I explained this to Dr. Buck and he has been so patient and understanding with me. I had to have another tooth removed, in preparation for Invisalign.

Something 5 doctors all refused to give me as an option because I'm a challenging case. The extraction was much more difficult and time consuming than I think Dr. Buck anticipated. He made sure I was completely numbed properly, and took the time to do it right. When it became clear it wasn't going to be an easy procedure, he stuck it out, all the way through and did not give up on me. I am truly grateful for that and the doctors here who have given me a chance!

I got on Yelp to help find a sedation dentist for my sister and came across Baseline Dental. I'm going to speak up now like I should have a few years ago. Admittedly, my teeth were not in great shape but is that any reason to treat a patient like I don't remember his name, but he's the tall blonde guy. He had the WORST attitude to be in a profession that takes some of us lots of courage to step through the door.

I felt shameful when I walked out. Shame on you as a co owner of a business! You're horrible. You have to give one to post, he doesn't deserve it. I do not recommend this Dentist.

Second time here was worse than my first. Gave them my insurance info over the phone for a cleaning and x-rays. After I come in for the x-rays they said they do not take.my insurance, and my insurance only covers one x-ray a year so had to go somewhere and pay out of pocket for it. Maybe staff should verify coverage before clients visits, would be super helpful.

It's been several years since my initial review, but I continue to be so thankful for all of the staff at Baseline Dental. I still make sure to make an appointment to see Heidi and Dr. Buck when visiting family in CA, and the front office staff are incredibly considerate with scheduling. Thank you for all of the great care throughout the years!

I am amongst the group that hates to go to the dentist, however I have never felt more comfortable. It starts with the Front Office. These ladies are The Best. Caring, Personable, and always Professional. I believe Dr's assistant is named Alex that helped me(always friendly, fun and informative. Dr. Buck is the gentlest dentist I have ever had(and I had my tooth pulled) He is Kind, Knowledgeable and will help wherever he can.

He takes the time to explain and answer any/ all questions you may have. If you are looking for a Dentist that will never let you down and will always give you the Best care. Call Baseline Dental

I had gotten a letter in the mail for an appointment I had missed stating that I owed 75$ for the missed appointment. I didn't know bout this fee so I called and explained that I had no idea. The woman on the phone stated I was given a warning and that this fee is shown on the paper you sign once you walk into the dentist. I have been doing everything over the phone and was not given a warning.

She says that back in 2009 I was given a warning for an appointment that I missed so that was my warning. I COULDN'T EVEN DRIVE IN 2009 I was 13 years old! She said that I stilled had to pay or I couldn't make an appointment. Then I stated I wasn't going to pay and she basically said ok bye and hung up. Super rude when I was being nice and explaining that nobody ever gave me a warning or told me about the fee.

So now they lost a 15+ year customer. I missed one appointment EVER when I was 13 years old & I couldn't drive myself to my appointments that was over 10 years ago. So don't say I've missed multiple appointments when I've only missed one in over 13 years.

Dr Rodriguez treated my 2 year old daughter after she knocked her front tooth out. Very comforting and gentle, my daughter didn't even make a peep. We utilized their ozone therapy (which is harder to come by but ohh soo useful) to prevent any infection, as well as speed the healing process and decrease inflammation.it worked wonderfully! The next morning all the swelling was gone and she was feeling much better. I cant wait for them to accept our insurance, as I would like my whole family to go here.

You don't have be a Stanford graduate with the highest of highest honors in statistics (nor have obtained a measly GED from a local continuation school for that matter) to know that 1 bad review out of 60 awarded to Baseline Dental Practice is an excellent tally to keep on a business review site like Yelp. Congratulations, BDP. Excellent job on that.

If I said that I only read 1 out of your 60 reviews, which one would you guess? If you guessed the bad review (which I'm sure you did), you'd be correct. Again, excellent job BDP. Wow, you're on a roll. However, your excellence ends here. Being on the receiving end of inadequate service presented by a business that gloats over 59 excellent reviews out of 60, the questions and doubts surface as to why one would be the exception. You, the reader, might even think that the problem derives from me, the victim, and not from BDP, the doer of mischief. Considering the odds and the stats, that accusation would indeed be a logical, fair and understandable one.

But please award me the audience to make my plea and tell you my woes so that you can be the judge. Hit it, Mr. Violinist. Mom needed dental care so I called to get rates for an exam with X-rays and the lady on the phone quoted me $65 for both. The lady on the phone (shame on me for not getting a name) also promised that if mom decided to have BDP do any dental work, the $65 would go towards the price of work performed.

That sounded fair, considering the fact that this was not going through any insurance plan. The only dental insurance plan she has is the limited cash amount in her purse. We scheduled an appointment and planned around the information given. Turned out that mom needed some work done, which was going to cost her $X.xx. She had it done. Once the work was complete, the BDP receptionist did not hesitate to charge mom the X-amount, in addition to the $40 for the X-rays, which was, in fact, a contorted version of the information we got from the lady on the phone.

This version actually worked against mom's limited cash amount in her purse, which in turn, benefited BDP's accounting reports at closing time that day. We pleasantly asked the receptionist about the the differences between the new price and the one quoted over the phone, to which she replied with a "that is not true" and a "who did you talk to".

After several attempts to get her to honor the quoted rates, we gave up. The insinuations of being labeled as fabricators of tales and weavers of fables was enough for us to back off. $40 was not worth the insult. We walked out with the intention to never return.physically. However, I vowed to return virtually. And here I am, your friendly neighborhood "yelper"--commending the righteous and chastising the misbehaved.

In this case, a business that refuses to honor quoted rates (that it doesn't keep track of) and/or chooses to change them dependent on the method of payment, then turn around and accuse the client of falsifying, is definitely labeled as misbehaving in my books, therefore, most deserving of chastising for its naughtiness. That, my friends, is the "old bate and switch", a practice notoriously known in the used car industry but not (prior to this point) within the tooth industry. BDP, here is your second "1-star" review to go with your 59 excellent reviews.

I've spent months looking for a dentist. After reading the reviews I chose this dental practice. I had a visit with the dentist on 10/01/19. Unfortunately I have nothing positive to share no one followed up with me to schedule my treatment. Disappointed is an understatement. I'm now forced to go through all this crap again with finding a dentist. I'll be in the office next week to pick up all of my xrays Update: My experience was unfavorable. Too much to go into here. I won't be returning

The staff is always friendly and welcoming - I was even informed 40 minutes before my appointment that they were a little bit behind, and I that should come 10 minutes later than the original appointment time. They do a great job communicating; they call to confirm appointments, they remind if one hasn't made and it's overdue, etc. The work done is always quick, efficient and an all-around pleasant experience.

Parking is always available and close to the door. The waiting room is never full. Open on Saturdays?! Very nice not having to take time off from work or school etc. There's nothing here to complain about. Always satisfied with my experience!

Great Dental place! Just started going here and the staff are amazing, very kind and welcoming! This is the first dentist where I did not feel "pushed" into trying to have something done. I'm very happy with this dental spot and will be staying here.

My wife and I have been going here for about three years. We'd tried a different dental office slightly closer to our house initially who treated us like a number and always tried to sell us something. BDP is so friendly and accommodating to our schedule. I had a tooth implant last year and had so little discomfort at any point. They never try to sell me anything other than making sure my teeth stay in good shape.

I have been going to Baseline Dental Practice since 1985. All of the staff is absolutely wonderful. They truly care about your oral health, and you as a person. The office is nice and clean. I have recommended this office to many friends and family who have also had great experiences as well.

I have been a patient at Baseline Dental for over 10 years. The staff there has always been professional and extremely nice. The front office always smiles and greet me as soon as I walk through the door. My Hygenist Heidi who I have gone to for many years has always made me look forward to coming in and have my teeth cleaned. When I needed work done the dentist were very nice too. I would highly recommend this office to anyone.

Searching for a good dentist has been a problem for me so I thought I would give online reviews a try. I was worried about going to find a new dentist because the last place I went was a disaster. I needed a dentist in Rancho Cucamonga so I searched review sites and saw Baseline Dental Practice had great reviews so I decided to give them a chance.

I had the same experience as the reviews I read. When I went there the front staff and everyone was really friendly. I saw Dr. Buck who was very thorough and explained the things I needed. The last place I went said I needed a lot of dental work done and didn't explain why. Dr. Buck said I needed less than half of the dental work the previous dentist said which is about what I expected in the first place.

He also explained why I needed a crown and showed me on the x-ray why it was necessary. When I went back for my cleaning they did such a good job. My last two offices I was in and out in like 15 minutes for the cleaning and it felt like they did nothing. At Baseline Dental Practice the hygienist took her time and did a really good job cleaning my teeth.

I have had such bad experiences at other places but here you just feel like you can trust them. I wish I would have known about them a long time ago. To top it all off they gave me a gift bag as I left. I will be telling all my friends. Thanks for everything.

I have been coming here for as long as I can remember. The receptionists are incredibly welcoming and provide a very comforting environment for clients. I've never had to wait very long and have even been taken in early. The hygienists are all very sweet, although Simone is my favorite. The rest of my family sees Emma, and they just adore her. The dentists are very professional and friendly.

I've had braces done here, cavities filled, and, of course, all my x-rays and cleanings. After 25+ years, Baseline Dental is the only place I have ever gone, the only place will ever go, and the only place I will take my family to. If you're looking for an amazing dental practice, this is the place.

This is the best practice. I've been going to them for years. They are accommodating with your schedule and always put me on a waiting list if I want a specific day/time and almost always call me to get me in sooner. Both Dr. Buck and Hernandez are so nice and gentle. I see Heidi as my dental hygienist and she is very gentle and kind. I highly recommend this practice to anyone. The front office girls are wonderful too!

I have been going to Baseline Dental Practice for over 20 years now. In all of those years I have yet to be given a reason to change dentists. Everyone there is incredibly nice and welcoming. They have always gone the extra mile to try and accommodate my busy schedule. I have had everything done from cleanings to wisdom teeth removal and I couldn't ask for a better experience through all of it.

Its always nice going in and seeing Gail and Teresa. They have worked there ever since I started going here and they make me feel like family. Anybody who is looking for a change and is tired of being afraid to go to the dentist I would highly recommend you make an appointment and see for yourself how nice of a staff this dental practice has.

I have gone to Baseline Dental Practice my entire life. I have had everything done from cleanings, fillings, braces, and wisdom teeth extractions. The Doctors and Staff are so friendly and they make you feel very comfortable. The office is always accommodating when I need to make an appointment. It sounds crazy but I actually look forward to my appointments. I can't imagine going anywhere else.

I have been bringing my family to Baseline Dental Practice for over 10 years now. I just started with me and my wife. Now we have a daughter and son who join us. I remember as a kid I hated going to the dentist. I haven't heard either of my kids say that when we talk about Baseline Dental. We always have a great experience from the moment we walk through the door, through the cleaning with any of the fantastic hygienists (Simone, Emma, or Heidi), to the friendly faces of the front desk staff while leaving. Dr. Hernandez has been great with me as well as my kids.

I have great admiration to someone who can make my kids feel at ease in a dentist chair while pulling one, two, three or four teeth at a time. Dr Hernandez has done that. On the few occasions I dealt with Dr Seguy, I have felt welcomed and well taken care of with his superb "chair-side" manner. On top of it all, the billing has been flawless. I would recommend Baseline Dental to anyone asking about a dentist.
