Great dentists and staff. Show great care for patients. Very thorough evaluation, take time with patients to develop a treatment plan, and excellent dental treatment and follow-up. Highly recommend AZPerio.

Staff and Doctor's treat me very well and explain things about the procedures so I can understand the process.

Dr. Houser and his team are fantastic. The entire procedure was completed in 30 minutes and virtually pain free. Tooth extraction and bone craft.

I was recommended by my dentist, but am very disappointed in my experience. It's too soon to talk about the results, but the experience was definitely lacking. I assumed they would be the experts and would be more informative--do not assume. 1. I would recommend asking for all post op care/follow up planning BEFORE the day of your procedure. ASK QUESTIONS--LOTS OF QUESTIONS! Don't assume they will adequately prepare you.

That is a huge deal. When I asked about it, They said they give thorough instructions and said having my 18 year old drive me was why I had questions. It seems appropriate for the patient to potentially have questions. Even when I took my teenage sons for wisdom teeth extraction, the maxillofacial surgeon's office went over all the post op at the consult so my minor children--the patient could ask questions. 2.

Another tip: Make sure they only work on the Left OR Right Side at one time. Im so disappointed they didn't suggest doing my treatment over 2 visits. Instead they recommended doing it all at once. Then post op instructions that were not given until after I had been sedated say not to chew ANY FOOD on the treated side until my follow up appointment more than 30 days out.uhh."the treated side" they did work on both sides of my bottom teeth.

When I called to ask they named the 5 teeth they worked on. I guess I'm weird and don't choose exactly which TOOTH I chew with--I can only control the side. The assistant on the phone agreed that would be "tricky" and it probably would have been better have done my work in two sessions. Now I'm stuck drinking smoothies for 5-8 weeks.

I saw Dr. McKnight for a tooth extraction in a preliminary exam followed up by an extraction 2 weeks later. Having had excessive bleeding in the past and now being on Plavix I was concerned but Dr. McKnight did the extraction easily and initially no excess bleeding but 7 hours later she had me return as bleeding increased more than expected. Dr. McKnight took a conservative approach and treated the area so that the bleeding was halted and I was comfortable.

We felt she was friendly, caring and extremely professional in all her treatment of me. All of the assistants were knowledgable, friendly and professional as well. While I center on Dr. McKnight who I'd highly recommend for care I think the entire staff is at the high end of professional care. The Practice is extremely busy but with all the patients you can still feel like you are cared for individually.

Although I have a fear of dentistry, Dr Houzer and his staff made sure I was comfortable during my procedure. In my initial appointment we discussed the best way to handle my fear and what my options were. The procedure was very quick and took less time than initial quoted.

My teeth felt so clean and gums well taken care of after Susan cleaned everything. Also the air polisher was fun and thorough. Thank you Susan! Then my "uncovering" of my implant posts went very well - Thank you Dr. McKnight!

The entire staff at AZPerio has been amazing for the procedures needed to be completed. Very friendly and professional, and the space is well kept. Dr. Reitan shows care and compassion for his patients and it is much appreciated!

I was referred to AZ Perio from my dentist. I was in a lot of pain and very swollen behind my left molar. I went on AZ Perio's website on a Friday night 10pm. I was contacted the morning of the next day. What a relief. The receptionist said she will call me back with a time that same afternoon. We went to the Pinnacle Peak office at 3:20pm to meet with Dr. Wilson.

Being a cancer patient and during these uncertain times I was worried about having a dental procedure done. I was very pleased to see the receptionist wearing a mask. Dr. Wilson and his assistant Neka were wonderful. I had a fractured root with a bad infection. Dr. Wilson explained everything to me and Neka followed through with my after care. They were both caring and professional. We also had a few laughs. Great experience. I'm very thankful for seeing me so quickly.

It took the dr and two assistants four attempts to place an IV. They were discussing their lunch order during this process. I wasn't given after care instructions verbally. My husband was handed a paper as we were departing. No follow up phone call received after tooth extraction and bone graft.

My experience with this practice was so incredible, I feel it is important to share. I had been in pain for a few weeks. After a dentist and endodontist could not determine what the cause was, I eventually made my way to Dr. McKnight who discovered that I had an infection and needed an immediate procedure, which I ended up having the next day. I have pretty significant anxiety around anything dental, so this was difficult for me.

The office itself is warm and inviting and the staff here was so incredibly kind, compassionate, and helpful, they made me feel so comfortable and safe every step of the way. They were very thorough and eased my worries about the procedure, process, payments, insurance, etc. (no surprise costs!). I've returned twice for follow ups and each time the staff remembers me by name and welcomes me.

I legitimately enjoy the visits! For something that was so scary for me, I couldn't be more thankful for finding this practice and would highly recommend it. I wish all my experiences with doctors were this comforting!

I would be extremely sceptical of going to AZ Perio. I was referred by my dentist to go get an opinion and and looked at for a implant on tooth # 13. I saw the doctor who did a 2 minute look and he recommended the surgery for the dental implant. I then went into a room and made appointment and was than told they need the $$ upfront for the scheduling.

I paid them $3500 to schedule appointment and left. I had 2nd thoughts on the surgery and felt super rushed into the surgery and decided to cancel my appointment and spoke with person who took my money and they said they would send back my $$ and call and schedule when ready. They only sent me back $3250 and stole $259 from me. Terrible way to try and win business.

No service was provided. I since have seen 3 additional surgeons to get 2 ND and 3rd opinions and was not charged $250 for a consultation. Very nice people but crooks. I will also be contacting channel 15 news and posting on every social media, Yelp to warn the public of their unethical practices.

Thank you Dr. McKnight for finally figuring out why the pain on my left side wasn't going away. The course of treatment had me free of pain in time for my vacation. I am so glad this portion of correction of what my dentist in Iowa dropped the ball on is over. See you in November for a normal cleaning. :

*I went to the Paradise Valley location, but I do believe doctor Dirk Donovan works also at the Central location. You know that when you have a gum graphing surgery just hours ago and are pleased enough to write a review on YELP, that your doctor did a super job. My options were to be knocked out ($500 upgrade to an anesthesiologist--and it scares me being knocked out!) or to take a prescription drug called Halcion that cost me about $4.

It made me feel tired and like I had about 2 glasses of wine. They numbed me well and I felt none of it. I was aware of what was happening, but I didn't care because of the music and the drug I was on. I also recommend bringing in your earbuds for some musical distraction. The assistants were wonderful and I regularly heard Dr. D. telling me small updates that were all positive. I'm in recovery and couldn't be more pleased by their attentiveness and plan for my mouth! I'd highly recommend Dr. Dirk Donovan and his team at AZPerio. Wasn't cheap, but there are some things worth spending money on!

Outstanding in every way. I required a tooth extraction and implant as a result of a fractured tooth. Dr. McKnight saw me the day after the fracture occurred. Everyone I encountered at AZPerio was friendly, professional, efficient and courteous. I received exceptional care and Dr. McKnight was wonderful. Everything prior to the procedure was explained thoroughly and my questions were welcomed and also thoroughly answered.

While I hope I won't need any future extractions or implants, if I do, I would not consider any other practice than AZ Perio, and Dr. McKnight. Definitely deserving of my five-star rating.

I cancelled a scheduled procedure to get a 2nd opinion. My credit card was charged and it was a follow up process to get my refund which I was told had to be "audited" and only a check could be issued for the refund. It took over 2 weeks and follow up phone calls. Not pleased with this process.

Great experience. The office itself was nice and up to date. All of the receptionists and assistants I met were very professional. Dr. Donovan was very personable. He explained what was going on in a clear and concise manner. I really appreciated his willingness to perform the treatment the same day. As a busy professional, it can be hard to make time. Like many, I am not a fan of getting shots in my mouth but I honestly didn't feel a thing. If you need a periodontist, I would definitely recommend AZ Perio.

This place is outstanding. I needed a tooth extracted and they took great care of me. I did not have an appointment and was able to go in the same day. Thank you Dr. Dirk. The staff is friendly and the office is clean and neat.

I have been going to this practice for over 20 years. I had a very bad experience the hygienist working on me seemed to be having a bit of personal issues and was extremely rough on my mouth the day of my cleaning. She actually picked my mouth so hard she ripped out one of my fillings my that was done less than two years ago! When I questioned Dr. Steven Rietan about it he acted like it was no big deal told me that I didn't need to fix it but out of courtesy he would refund me the price of my cleaning?

He then sent me a letter and told me to never come back to the practice again! What a bunch of unprofessional people almost like gradeschool! I have reported them to the dental board and I would not recommend going to these people very poor customer service nasty to say the least and charging somebody $160 for a cleaning I guess one would just expect a little bit more.

I have never been talked to so rudely on the phone with a business! WOW. I had to cancel an appointment because I found somewhere else and the lady told me I was supposed to give 48hr notice of cancelation, which is the first time hearing this. She also stated "I guess I'll try and book Dr. McKnight with another patient." Like I am sorry I was honest with her and stated I truly did forget. Not a good way to promote more customers.

Dr Donovan recently performed a surgery for which I was very nervous. He and his staff had great personalities and gentle bedside manners; they helped me feel comfortable throughout the procedure. I was surprised by minimal discomfort following the procedure, his stitches were done very well and my gums healed beautifully.

From what I can see from other post is that every AZ Perio office is very different. As for me my Periodontist is Dr. Dirk Donavan. His office is located in Central Phoenix. Adress: 5300 N Central Ave #130, Phoenix, AZ 85012. My experience was phenomenal! You couldn't beat the price, the customer service from the whole staff-- front office girls to the dental assistants-- and how smooth, almost pain--free the procedure went and there was really no pain after or during the healing process. I would definitely recommend this AZ Perio location!

My gums had been receding for years. My dentist finally put his foot down and ordered me to see the periodontist whom he himself saw for his own gums, Steve Reitan at AZ Perio. As influential as my dentist's recommendation was, I still decided to get two opinions, going for a consultation both with Dr. Reitan and with another highly rated periodontist.

I opted for Dr. Reitan. Long story short: I am fully satisfied with every aspect of my interaction with AZ Perio. After the surgery, Dr. Reitan phoned me and said that I could call him on his personal cell phone if I had any questions or concerns. How many doctors give their patients that level of accessibility? But most importantly, my gums are still healthy and pink two years after the surgery. I enthusiastically recommend AZ Perio to anyone in need of periodontal care.

Went to AZ Perio for the first time today for a tooth extraction. The offices are beautiful and state of the art. The front office staff was very welcoming and helpful. The receptionist was gracious. The back office staff were professional, helpful, friendly and supportive. The dentist, Dr. Donovan was gentle and efficient. The entire staff made me feel comfortable and cared for. Dental procedures can be expensive, but they provided a professional explanation of the costs and expected insurance reimbursement. I could not have had a better experience.

Horrible experience! They were very pushy, rude and refused to work with my insurance, even though they are contracted with them. They even went as far as to say "most people who come here don't care about insurance and just want the work done." Well, most people I know do care about insurance first as dental work is not cheap! I found them to be the " meat market of perio dentists" and all they seem to care about was the money, certainly not the patient.

They may have nice fancy offices, but I don't care about how an office is decorated. I care about the capabilities, skills/knowledge, behavior from everyone sitting at the front desk to the surgeons/nurses.
