A board-certified internist who takes the time to listen, runs the labs in-house, and still makes house calls for the patients who need them most. Care the way it was meant to be — measured, personal, and yours.
Dr. Nathaniel P. Fleischner, MD, opened his West Palm Beach practice in 2002 with one conviction: that internal medicine works best when the physician has the time to think. Twenty-three years later, that conviction has only deepened. Visits here run thirty minutes, not twelve. Questions are encouraged. Phones are answered by people, not prompts.
We are a small practice on purpose. A single physician, two medical assistants, and a front desk that knows your insurance before you finish explaining it. We do not chase volume. We chase the diagnosis — the one you came in for, and the one you didn't know to ask about.
From annual physicals to the management of complex chronic disease, the standard here is simple: explain everything, document carefully, and follow up. If you have been looking for a doctor who picks up the phone, you have found one.
Hypertension, cholesterol management, arrhythmia monitoring, and pre-operative cardiac clearance — with same-day EKG in the office.
Type 2 diabetes care, thyroid disorders, and metabolic syndrome. We pair A1c results with a real conversation about your meals and your week.
A ninety-minute yearly exam with full bloodwork, EKG, and a written summary you can actually understand. Bring your questions.
Complete blood count, comprehensive metabolic panel, lipid panel, and TSH — drawn on-site and resulted within twenty-four hours.
Coordinated management of hypertension, asthma, COPD, and reflux — including refills, between-visit check-ins, and specialist referrals.
Same-day appointments for fevers, infections, and acute concerns that are not emergency-room problems but should not wait a week.
No surprise bills, no mystery codes. We accept most major PPO insurance plans and offer transparent self-pay rates for the uninsured. Indicative prices below reflect typical self-pay cost; insured patients pay only their copay and any remaining deductible.
The office is staffed Monday through Friday, with early morning appointments reserved for working patients. After hours, our answering service reaches Dr. Fleischner directly for urgent concerns — not a nurse triage line, not a chatbot.
After hours: Existing patients with urgent concerns may reach the answering service at any time. Dr. Fleischner returns calls the same evening for issues that cannot wait until morning.
Tell us a little about what brings you in. We will call you back within one business day to confirm a time, verify your insurance, and answer any questions you have before the visit. New patients are welcome.
