Dr. Costner is so amazing. I went to several dermatologists for my issue and she was the only one who took an initiative on solving the problem. She is known as a “problem solver “ by other physicians and I can see why. She takes hard cases and enjoys figuring out what is going on. She went the extra mile for me and I have so much faith in her. She has a very inviting personality and is extremely encouraging and optimistic. Dr Costner is very intelligent and I look forward to my future appointments.
