I practice traditional Mt. Sinai trained medicine, with a great appreciation for Integrative and alternative approaches. I look for the latest high-tech approaches including genetic testing, neurocognitive screening, and testing with ‘liquid biopsies’ by a blood test that picks up very early cancers.
I am very open to questions, and I have many years of extensive relationships with excellent subspecialists in various hospitals around the city.
With Elsa, my amazingly competent ‘right hand’, I am available by text when you have a sudden medical concern, when you need lab or X-ray results quickly, a medication refill, an appointment or timing issue, a Covid or booster question, or a question about medication in the news that might pertain to your health.
Elsa Manelli is the heart and soul of the concierge practice. Primary contact person and office manager. Elsa receives and responds to texts and calls reliably, compassionately, and supports me, Stacy, and my patients in a caring and timely fashion. She has trained Allison and Cintia, my office staff, to be equally caring and responsive. Treat them all well, please!
I want to work with patients who appreciate collaboration! ‘You and me versus the issue at hand’.
And I am fortunate to work alongside a wonderful physician assistant with 15 years of experience named Stacy Beaupre who is very involved in integrative care and will be helping me evaluate neurocognitive function. She too is available and on-call.
I can only take a limited number of new concierge patients and I welcome a scheduled five-minute phone conversation where we can see if we are a good fit for one another.
