John P. Leonard, MD

Midtown East isn’t just corporate towers and UN diplomats—it’s also where specialists like John P. Leonard, MD practice. The 19th floor of 240 E 38th St puts them squarely in the mix, a few blocks from the East River and the Murray Hill hustle. Hematology isn’t the kind of field that lends itself to walk-ins, but for those navigating blood disorders or lymphatic system concerns, the address is one to note. Restrooms are available on-site, which, while not glamorous, matters when you’re dealing with lengthy consultations or pre-treatment prep.

Blood cancers and clotting disorders don’t adhere to zip codes, yet proximity still counts when you’re coordinating scans, infusions, or second opinions. This stretch of 38th Street is quiet compared to the chaos of Grand Central, but it’s well-connected—close enough to the 4/5/6 trains and the FDR for anyone coming from Queens or uptown. The focus here is clinical, not cosmetic; if you’re mapping out treatment options, the location’s accessibility might factor into the equation more than the view from the 19th floor.

Scheduling an initial consultation usually starts with a call to (929) 573-0994, where they’ll handle referrals and insurance details before you step into the office. For first-time visitors, the building’s entrance is unassuming—no neon signs, just a standard Midtown lobby. If you’re plotting the route, the map clarifies which side of 38th Street to aim for, since the block splits personality between medical offices and residential holdouts.
