“Dr Liebowitz is the closest doctor to a homepath that I have experienced - and that's an excellent thing. He asks questions and pays attention to everything happening in yor life. He tests and is not in a rush to just write a prescription. So I trust his advice.”
Imani M.March 11, 2026
“I have never had a bad experience with Dr. Leibowitz. In fact, I look forward to our conversation given his upbeat attitude and funny jokes. He always has his best intention for his patients and I never feel a lack of care. My appointments have always been quick and concise which helps if you’re busy.”
