Kimberly R.OnI of the most comprehensive and thorough dentists with real interest in the patients and best care for them. I would recommend Dr Mahler to others looking for an experienced and caring dentist. Their staff is also amazing.
Sid P.Always 5 stars! He’s THE expert in TMJ and problem cases like mine😁
Laurie C.Flawless.
KanuExperience is always top tier! Staff and doctor very friendly
derrick r.Dr. Mahler has been my dentist for over 20 years. He is very proactive at planning the next step of treatment. He managed a complex dental implant and bridge situation for me. He also has put plans in place for my daughters and we have been able to avoid orthodontics.
Jennifer B.Great expertise. A 1 in a million phenomenon. The destroyer of TMJ. Other dentists tremble at the sound of the name doctor Mahler (and I’m not talking about the weight loss doctor in Lockport) because they know they cannot compete no matter how hard they try.
Missael S.The staff is very friendly and helpful. The care I receive is exceptional and the interest regarding my overall health is comforting and reassuring that I am being listened to not just regarding my dental health.
Michael D.I went in for an appointment to start the process of getting Invisalign, ended up finding out about other more important issues going on in my mouth. Thanks Dr. M. for being honest and candid about the health of my teeth and gums. Health is more important than aesthetics!
Erica M.Dr. Mahler really took his time with me and made me feel listened to. The consultation I had was a very positive experience.
