Dionysios Neofytos

Infectious-disease specialists bridge everyday care with specialist insight when symptoms point beyond routine diagnoses. Dionysios Neofytos fits that role, focusing on complex or unusual infections that need targeted diagnostics and treatment. Their approach is rooted in precision rather than guesswork, a useful baseline when your GP says, “This one’s a bit trickier.”

Find them at 1275 York Ave, New York, NY 10065, a quiet stretch of the Upper East Side near major hospitals. The Upper East Side itself is calm and residential, an easy walk if you’re already in the neighborhood, or just a short ride from midtown or the East River bridges.

Call (212) 639-3244 ahead if lab work or imaging is part of the plan—many visits start with blood tests or scans elsewhere before they review the results. They manage everything from Lyme disease and tuberculosis to post-transplant infections and antibiotic-resistant bugs. HIV care and pre-exposure prophylaxis (PrEP) consultations are also part of the mix.

When you’re ready, pull up the directions and head over; the building sits between 72nd and 73rd streets, steps from Lenox Hill Hospital. York Avenue is one-way northbound, so leave a little extra time if you’re driving.
