I've been using Mark for 30 years I definitely love his old school approach of gentle and kind. I will not ever use another dentist unless I have to have surgery that Mark can't do

★★★★★ 5.0 Randi Blakeburn · Jan 2024

He recently did some extensive dental work for me. I was anxious over nothing. He did an excellent job. He's very personable, knowledgeable and non-judgmental. His prices are now than reasonable. I am now taking my 11 year old to him and she likes him, too. Thank you, Dr. Medder! I wish I would've met you years ago.

I went to Dr. Medders for fillings and spent about $1000 just for him to improperly fix my teeth to the point I need multiple root canals, extractions, and re-done fillings and am at risk for losing my jaw now to the point I'm now on a max dosage amoxicillin and Clavulanate prescription. He argued with me multiple times about it and gave me the "I know more than you you don't know what you're talking about" attitude towards me despite describing how the fillings he did has fallen out, and would threaten to kick me out if I complained about him not working on the teeth that were causing me the most pain. He also did an improper amalgam filling where he didn't clean out all of the infected material which now means my nerve in that tooth is infected down into my jaw. Out of all of my dental e

★★★★★ 5.0 David Malone · Mar 2021

Amazingly quaint and personable. I haven't been to a dentist in many years, he didn't shame me or make me feel bad about it at all. He simply took care of the problem I was there to take care of, removing my tooth. He made me feel completely comfortable, made me laugh and joked around after I felt some pain and needed more numbing agent. 85 Dollars for the appointment, x-ray and extraction. Couldn't ask for better, can't wait to go back next month for some more work. Would recommend to anyone needing affordable dental work done.

★★★★★ 5.0 Nik LeMoine · Sep 2021

Hadn't gone to a dentist in years because everyone I've gone to shamed me. Dr. Medder was very kind and understanding. For the first time in my life I'm actually looking forward to booking a routine cleaning.
