Patient Reviews

"I went to see the dr for a third opinion and I left devastated that I did not meet him at my initial diagnosis. It was obvious that he is brilliant as well as sincere and genuine. Traits that today many people in the medical field no longer have. I feel hopeful that I have him in my corner now and will be switching over when the time is right. š"
