Had a filling redone by Dr. Cossmann after 3 failed attempts by different dentists. He was punctual and extremely friendly. He gave me extra time to allow the freezing to work. During the procedure I barely felt anything (previous dentist tortured me). I could tell he spent a good amount of time making sure the filling is done properly this time. His staff is also amazing including the receptionist. Best dentist I ever had.

I've been going to Dr. Cossmann for 20 years and have nothing but glowing reviews! His staff are incredibly friendly and professional, the office is clean and bright, and I've never had to wait unlike most doctor's offices. I'll never go anywhere else.

Have been going to Dr Cossman for many years. Have never had a issue. Have been able to get me in to work on a broken tooth within days. Relaxing place for someone who is uptight with dentists

Dr. Cossman was recommended to me by a friend, I am so glad I listened and have become a patient of Dr. Cossman. I have now been a patient for 6 months and have had great experiences with Dr. Cossman and his staff. The staff are friendly, helpful, and always on time. I had bad experiences with my previous dentist so I am so grateful to have found a wonderful dentist close to home.

Horrible. All my treatments here went wrong. I got a root canal and it took months to get better. A tooth extracted and am still dying of pain. The med they give is of high dose and if you don't take it you die of pain. If you take it you did of nausea and vomiting. The doctors knowledge of anything is horrible. Every time you go they change their words. The prices change based on your insurance
