Dr. Troum is excellent. I was referred to him by my primary care doctor, and Dr. Troum was a wonderful surprise. Thorough, thoughtful, patient, attentive--I wish every doctor I saw was like him. He also has a sense of humor, which I appreciate. I trust him.

Dr. Troum listens intently to patient concerns and does not brush them aside. He communicates and shares ways ways that the situation can be approached, and with sensitivity includes the patient in the process. He is very respectful and never brushes asside what the patient says or asks.
