Dr. Jun is the first doctor, dentist in 23 years to listen to me about serious pain I have been going through. Dr. Jun, you have given me some HOPE that I may not have to live with this pain forever, I am so grateful for your interest. P.S. My tooth experience was perfect. Thanks.

This is the most professional staff and compassionate physician I've encountered. I'm in healthcare and this is such a rare find these days. I have nothing but remarkable things to say. I had the best care and treatment ever!!

So glad we choose Dr. Cooper over the other referrals we were given! That initial contact with his staff was so positive and informative that it made our decision very clear. Then to meet and be equally impressed by Dr. Cooper's cheerful relate-ability and expert skill instilled a great deal of confidence! It was a positive experience all the way! Thank you!!!
