Having had abdominal pain for many months, I met with Dr. Castor and am grateful that he was recommended to me. His patience, thoroughness, concern, and medical expertise were so different from some other physicians with whom I had met. He is a wonderful doctor and has been helpful to me from the first time I met with him. I highly endorse him.

Dr. Castor is a wonderful, thorough, compassionate, extremely knowledgeable doctor. This man has been an integral part of literally saving my life as I was diagnosed with Dysphasia. Along with his care and several other healthcare specialists I have gained my life back but, he is the one that has brought it about. Cannot say enough good things about him.

I recently have been having some problems with my stomach. Dr. Castor has been awesome in contacting me in reference to additional testing to make sure he doesn't miss anything and gets back to me promptly with results! I appreciate so much the time he has devoted to my care! Thank you so much Dr. Castor!
