Dr. Ari Kostadaras MD

Kidney health isn’t something you notice—until it’s not working. In Astoria, where the daily hum of city life can overshadow quieter medical needs, Dr. Ari Kostadaras MD offers a specialty that often flies under the radar. Nephrology might not be the first word on everyone’s lips, but for those managing conditions like hypertension, diabetes-related kidney disease, or electrolyte imbalances, it’s essential.

The practice sits at 30-16 30th Dr, a stretch of Astoria where residential buildings give way to small medical offices and the occasional café. It’s the kind of block where neighbors recognize each other, and a specialist’s presence feels like a quiet anchor. Here, the focus is on diagnosing and treating kidney disorders, from early-stage chronic kidney disease to more complex cases requiring dialysis oversight or transplant coordination.

Questions about kidney function, fluid retention, or unexplained fatigue can be directed to (718) 721-4440. The office handles referrals, but patients can also reach out directly if they suspect their symptoms align with nephrology care. Blood pressure management, glomerular disease evaluation, and metabolic bone disorders tied to kidney health are among the issues they address.

Directions to the office are straightforward: a map is available here. Astoria’s mix of transit and walkability makes it accessible, whether you’re coming from the N/W train or the Q102 bus. No need to cross boroughs for a consultation—just a short trip to a practice that treats kidneys like they matter. Which, of course, they do.
