At the office of James H. Zellner, MD, every visit begins with a conversation — not a clock. We practice integrative family medicine in the heart of Brooklyn, blending evidence-based clinical care with the patience your health deserves.
Annual physicals, age-appropriate cancer screenings, immunizations, and laboratory work designed to catch issues before they become problems.
Ongoing, coordinated care for hypertension, diabetes, thyroid disorders, asthma, and other long-term conditions — with regular follow-ups and medication management.
From pediatric check-ups to senior wellness visits, we provide continuous care across every stage of life — for individuals and families in the Brooklyn community.
Nutrition counseling, stress management, sleep optimization, and weight management programs grounded in current clinical evidence and your personal goals.
On-site laboratory services including blood work, urinalysis, rapid strep and flu testing, EKGs, and coordination of specialty imaging when needed.
When illness strikes unexpectedly — infections, minor injuries, allergic reactions — we accommodate same-day appointments for urgent but non-emergency concerns.
James H. Zellner, MD, built his practice on a conviction that effective medicine requires more than a quick consultation — it demands a sustained relationship between physician and patient.
Located on 5th Avenue in Brooklyn, our office has served families across generations. We combine the rigor of evidence-based clinical practice with the attentiveness of a physician who remembers you — your history, your concerns, and your goals.
Whether you are managing a chronic condition, navigating a new diagnosis, or simply looking for a primary care physician who treats you as a whole person, we welcome you.
Every appointment begins with your story. We take the time to understand your symptoms, your history, and what matters most to you.
Medical jargon has no place here. We translate findings into plain language so you can make informed decisions about your health.
Treatment is a partnership. We outline options, discuss risks and benefits, and build a plan that fits your life and your values.
Care doesn't end at discharge. We track outcomes, adjust plans as needed, and remain accessible between visits when you need us.
