Dr. Troum is the best. When I see my other doctors and they ask me who my rheumatologist is and I tell them, they all have positive things to say about Dr. Troum. It is clear that he Is highly regarded by his colleagues. Dr. Troum is very personable, understanding, empathetic and so knowledgeable. Glad to be in his care.

He is my favorite MD. He takes time to review any blood work and tests that have been done since the last visit no matter who has ordered them. He patiently answers my questions. Any orders he gives me are clearly explained. He is the best!
