THOMAS L. PITTS, MD REVIEWS

Absolutely the most knowledge Doctor I’ve ever had. He is very concerned and does an excellent job of delivering proper care. I’ve been a patient for over 20 years.

Very thorough and knowledgeable! I recently moved out of state but will continue to travel back for my appointments with Dr. Pitts because of the great experience I have had.

Great doctor, caring and knowledgeable helps me very much.

WAHID KASSAR, MD REVIEWS

Excellent experience! Dr Kassar was very nice, helpful and he took time explaining everything to us. The RN and the young man by the registration office were outstanding. Mallika was awesome, she went out of her way to call pharmacy to help us get the prescription. Everyone was polite, knowledgeable and willing to help. We would highly recommend dr Kassar and his crew. This was our first visit and we are impressed by everyone being so kind.

I have been a patient of Dr Kassar's for approximately 20 years now and in my opinion he is the absolute BEST endocrinologist ever! He has an excellent bedside manner, he listens and he understands that every patient is different and not a "one size fits all" when it comes to treatment. He saved my pregnancies, he helped me tremendously with my hashimotos symptoms and he took his time to listen to everything that concerned me and gave me solutions. I recommend this doctor 100%

My husband and I had a great experience with Doctor Kassar. Very knowledgeable and take a very good care of his patient. Gave us enough time, answers all the questions.
