However, after today and my first appointment with Dr. Jama, I'm staying. I was really pleasantly surprised with Dr. Jama. She was very prepared, engaging, and extremely competent. Most importantly, she was very nice and seemed genuinely concerned with my health and well being. I felt like a valued patient again.

Dr. Jama is wonderful. I was not happy at having to change HCP due to my recent insurance change. Dr. Jama truly won me over with her knowledgeable and helpful manner. She took time to listen to my health concerns and even went beyond my expectations by finding an affordable replacement to a very expensive medication. Dr. Jama has seamlessly continued my healthcare plan, even making a few good changes. I feel that I hit the jackpot in finding such a terrific new doctor.

External Professional Relationships

Pharmaceutical, device, and biotechnology companies frequently collaborate with basic scientists and physicians within an academic medical center to help advance science and improve patient care.
