"The most important thing I can offer isn't a credential — it's presence. The ability to truly listen, to sit with someone in uncertainty, and to hold space without judgment."

MSN, APRN, FNP-C · Founder, Zadaka Health
Leor Zadaka is a board-certified Family Nurse Practitioner who founded Zadaka Health around a simple but rarely fulfilled promise: that people navigating ketamine therapy and natural medicine deserve both exceptional clinical care and genuine human connection.
Leor earned his Master of Science in Nursing from Georgetown University with a, with additional training in psychopharmacology from the Neuroscience Education Institute. Before founding this practice, he built a career across healthcare's most demanding and emotionally complex environments — oncology, end-of-life care, emergency medicine, and dedicated ketamine therapy clinics. These experiences didn't just sharpen his clinical instincts; they deepened his understanding of what people actually need when they're going through something hard.
Outside the clinic, Leor is a devoted dog dad, an avid hiker, and someone who finds deep meaning in connection with people and the outdoors. His patients consistently describe him as someone who makes them feel genuinely heard — not because it's a technique, but because it's who he is.
"I had been through multiple providers before finding this practice. The difference was immediate — the level of care, the time taken to understand my history, and the sense that I was genuinely seen as a whole person."
