"Worst clinic in Manhattan. They have super unprofessional staff at the front desk and their teams don’t talk between them. Reception tells you one thing and the doctors / nurses another thing."

Online review

"The practice has drastically went downhill. They focus on a “concierge” service first and foremost. If you don’t pay for that added feature the service you will receive is abysmal."

Online review

"From the very first visit, they have been thorough, attentive, and genuinely caring. They take the time to listen to my concerns, explain things in clear and understandable language, and never make me feel rushed."
