I was recently hospitalized with Deep Vein Thrombosis (blood clots in major veins) and diagnosed with a blood clotting disease. Dr. Letzer was assigned as my hematologist while I was in the hospital and I was very happy with his care. He was patient in answering my questions and really seemed to know what he was talking about (which, I found, is a rarity in hospitals). I talked to several other hematologists who had never even heard of the disease I was diagnosed with! His office is very nice and the office staff is friendly. The only problem I've had so far is in getting the office staff to call me to let me know the results of testing I've had done. But, all in all, I'm happy with this office!
