Dr. Lowenthal has been my oncologist for over 10 years. That alone should be an endorsement, because not that many cancer patients get to live that long. He is smart and stays on top of the current literature. He always has time for my questions and never treats them or me as trivial. Furthermore, his staff is compassionate and kind, especially the oncology nurses. Only complaint is that the office is often hectic and he’s almost always running late. Making appointments early in the day saves wait time.
