Makers have made dentistry a social science COVID 19. I asked already about Drs. Roth and Wong.

I recently moved into the Danville area and was looking for a dentist. I was lucky enough to be referred to Dr. Koenen from my orthodontist. For as long as I can remember the dentist has usually started with me having an anxiety attack and ended usually in tears. I was nervous going into my first appointment but Dr. Koenen made me so comfortable. He answered any and all of my questions. I had to have a couple fillings taken care of and he walked through every step of what work he was doing, when he was switching instrument, and made sure I was doing okay the hole time. I truly cannot thank him and his office staff enough for being so kind and professional. I can honestly say I am no longer nervous or anxious to go to the dentist anymore because of Dr. Koenen.

I have been going to Dr. Koenen for dental care for over 10 years. Dr. Koenen makes you feel comfortable, explains all that he does, and answers all your questions. His staff are genuine and so friendly. I am so thankful for Dr. Koenen! I don't think my family will ever find a better dentist! Thanks Dr. Koenen!

I have had several root canals that require a crown done by another dentist and today I had a crown done by Dr Koenen. I notice a big difference in the quality of procedure he did. The crown fits nicely tucked into my gums wheres I can feel where the others stop right at the gum line.

ANOTHER great experience with Mark and his staff... had a filling bail out on me, and fortunately, they had an opening SAME DAY (thankfully it was a reasonably quick repair, no anesthesia reqd).

I don't like going to a dentist! Who does, LOL :) However, after all the years going to Dr Koenen, I feel great about it, and have absolutely nothing negative to say about my experiences. Would absolutely, and already have recommended him to friends and family!
