I needed an emergency evaluation for an infected tooth. I received an appointment the next day, and the tooth was removed at the same appointment. Dr. Anderson is excellent. He is patient, thorough and kind. The office staff and assistants are equally outstanding. The office is very clean and comfortable. I will be returning for an implant. Do not hesitate to call Cornerstone for any periodontal needs.

Beautiful place. Very friendly staff that made me feel comfortable and totally understood my anxiety issues. Wanting to take the time to analyze exam and x-rays to develop a personalized plan that works best for me was very important. Would highly recommend.

Gail T., Batavia

Dr. Anderson and his staff were congenial and efficient in their very welcoming and bright office during a recent procedure I had done there. Not only were they flexible and able to coordinate with my prosthodontist, but personally escorted me there. Excellent dentistry, excellent care! Thank you!

Dr.Yerke does a thorough job and really cares about her patients. I can come to her with any question and concerns and she’s always there to help. Amazing experience with her and all of the staff.

Peter T, Buffalo

I was very fortunate to be referred to Dr Yerke by my NYC Periodontist, when I moved to Buffalo. I'm having two implants done and have always felt confident that I am in good care with Dr Yerke and Teresa. The treatments are relaxed and painless. Dr Yerke explains the op, and post-op phase, in a straight-forward and easy to understand way. Dr Yerke always personally follows up, and is available for questions post-op. She is clearly passionate about what she does, is highly knowledgeable and makes the right calls. I also do cleanings with Jennifer, and recommend her highly. The front desk staff are always welcoming and are a pleasure to deal with. I would recommend Cornerstone without hesitation.

Barbara N, Tonawanda

Always enjoy being taken care of by Jennifer. She’s great

Linda D, Williamsville

Kind ready to serve staff and excellent Doctors.Always a good experience

Marie T., Bovina Center

My daughter, also a dentist, referred me and my husband to Dr. Corbelli at Cornerstone for help with some issues not too many dental practices can tackle. Cornerstone is a top professional office with a very caring staff and beautiful up to date facility. They use top of the line diagnostic machinery. Dr. Corbelli was very thorough in his exam and his explanation of what was needed and why. He and the rest of the staff treat patients with the utmost of care. I highly recommend this practice for periodontal issues and implants.

Linda P, Lockport

I am very happy with all of my appointments & staff

Bill S, Tonawanda

I am a new patient there and I was very impressed with the level of service and detail. I have spent 45 plus years in retail customer service and I am very conscious of what it takes to do the job. They get it, treating the customer as if they are there only concern. Thanks for a great first impression.

Carmelo S, N Tonawanda

I had an emergency and it was wonderful to find a dentist that cared enough about someone who was in pain and not a patient to fit me in the same day and take care of my emergency , a great practice that cares about people , highly recommend if you’re looking for a new dentist

Mary Beamer, North Tonawanda

I actually went to a different dentist due to the office being kind of far away from me, but I ended up returning back to cornerstone despite the distance, just because I like them so much. I used to be nervous about going to a dental appt, but at cornerstone, I'm not. They're always extremely gentle, caring, and kind.

Leslie O, Lockport

Drs and staff are all wonderful. Very professional.

Mike K., Williamsville

Service was fantastic and professional. Seems a little pricey.

Gloria M, Niag Fall

Bonnie W, Lewiston, NY

From the moment I walked in until I walked out, my visit was exceptional. Reception was very friendly, the assistant had an amazing demeanor and did a fantastic job of helping me understand the process of my visit and subsequent extraction, Dr. Ryan was very knowledgeable and thorough. It was such a good experience that I had to make sure everyone knew upon my departure. I really never thought that having an unexpected molar extraction could be such a good experience. Thanks to all for being so wonderful!!

Terri H., Tonawanda

Char C, Wilson

I was so worried about having this procedure done. I’ve always taken care of my teeth but I’ve cracked a back tooth that is beyond repair (darn cherry pit). Everyone is so friendly and helpful. Dr. Yerte explained everything and answered all my questions. I’m looking forward to going back and having my surgery and dental implant done because I know I’m in good hands.

Christopher G., Lockport

From the moment I walked in to the moment that I left, the staff at Cornerstone Periodontics made me feel welcomed and highly valued. This was my first time coming in and I have never had a better dental related experience to date. Everyone that I encountered at Cornerstone introduced themselves and made sure that my experience was a comfortable one. Renee at the front desk was very helpful, and I had the pleasure of being seen by Audrey, Sarah, and Dr. Yerke who all made me feel as if I were a part of their family. Dr. Yerke not only examined for my dental needs, but she also took the time to educate me on what was going on and what I was seeing. I left the office with a smile on my face and gained a lot of new knowledge from the help of this amazing staff. I highly recommend Cornerstone Periodontics and Dental Implants for any and all of your periodontal needs!
