Dr. McDonald and his staff are amazing! Compassionate, professional and by far the best dentist I have ever had. And I have a number of dentists since a child; 10 cities in 5 states. That is more than most so I feel well informed to confirm that he is the best.

- Leigh S. , Patient since 2013

I was terrified of the dentist until I went to Dr McDonald. Now I'm not and actually enjoy my visits. I hadn't seen a dentist in 20 years when I saw Dr McDonald for the first time with a jaw infection. Now I'm close to having a new smile. Everyone in the office feel like family!

- Robyn M, Patient since 2012

Dr. McDonald is positive, frank. easygoing and most importantly I trust him. I am a former employee of a large software company nearby. I changed employers 9 years ago and despite the fact that my home and current employer is in Seattle I travel to the Eastside to see him and his amazing staff.

- Stephanie D. , Patient since 2004

Dr. McDonald and his staff are always so understanding of my needs. They listen and always check in with me to make sure I am comfortable and if there is anything else they could do to help. I always receive an answer to my questions. And I love that I get a f/u phone call after each appt. The staff here are wonderful!

- Ashley K., Patient since 2011

Dr. McDonald's thoughtful attention to my specific circumstances has been very much appreciated for many years. His experience coupled with extraordinary dexterity help make him an exceptional dentist. It is easy to understand how he's been able to surround himself with such a strong staff.
