FounderBryan built Prefusion around one idea: therapies are a dime a dozen in New York, and what actually changes an outcome is the data underneath them and the people who read it with you.
He runs the practice across all three New York locations, sits in on consultations himself, and set the rule the whole clinic works to, that nobody is prescribed anything before a DEXA scan and a full blood panel are on the table.
