“Dr. Shor, the medical and admin staff are all great. They helped save my life literally. My health had deteriorated to a point where I was somewhat concerned about surviving. Now I’m feeling good again. Thank you”
Verified Patient
“Dr. Shor is the ‘best doctor’ I have known. He has saved my life about Lyme. He is kind, courteous and intuitive.”
Verified Patient
“Have seen a number of internists over the years, and just want to say that Dr Shor is NOT your average internist. He knows so much more about so many things, and is able to help, when another internist would have to pass you off to a specialst for anything but the very basic problems. Beyond that, it's obvious that he truly cares about his patients, doesn't overcharge, and works long hours to give everyone the very best care. I sincerely trust him with my life. Can't imagine that you could find a better internist. Please don't ever retire!”

“When I first met Dr. Shor, I was in intensive care, 29 years old, and frightened. I was very ill. He was direct but kind. He didn't tell me what I wanted to hear, but he told me what I needed to hear. In the past, I often felt patronized or marginalized by health professionals. Dr. Shor gives his patients respect, validation and the truth. I have chronic illness (Crohns disease and Lyme). Under Dr. Shor's care, I believe that I am a part of a treatment team. There is honest dialogue and trust between us. His excellent patient care should be the standard, not the exception. I am grateful to be his patient. Sterling, VA”

“Miracle worker is the term I would use to describe Dr. Shor. There is no other doctor who treats you with respect the way Dr. Shor does. You are truly a part of your own healthcare team. If this is not enough, Dr. Shor really listens and addresses all of your concerns. You never feel rushed or that your concerns are not valid. I know that without Dr. Shor I would not have gotten my life back. I have gone from someone who was so fatigued that I had become isolated because I was unable to perform even the simplest of tasks on a daily basis to someone who has begun to have a life again. Words can never express my gratitude. You are truly a rare doctor and person. You have set a standard that all doctors should aspire too. I am just grateful that I am one of your patients”
Verified Patient
“Dr. Shor, You have helped so many people and I would love to write a testimonial. Just had lunch with a friend last night and she said she couldn't believe how much my health has changed and she remembered when I used to be so sick, go to the hospital and have such exhaustion I couldn't get out of bed. So amazing how much you have changed my life! I can never thank you enough!”
