About the practice

Healthcare that
starts with listening.

A two-location primary care practice built around the patient-doctor relationship. Bilingual. Walk-ins welcome. Same-day visits every day we're open.

Our mission

At Lake Nona Medical Services, our mission is to provide accessible, high-quality primary care to every patient who walks through our doors. We believe healthcare should be personal, thorough, and grounded in trust. Whether you are managing a chronic condition, need a routine physical, or require immediate attention, we are here for you.

What we believe

01
We listen first.
Most clinics treat patient time as a constraint. We treat it as the point. Real care starts with a real conversation.
02
Bilingual is a feature, not a footnote.
Spanish-speaking patients deserve the same depth of care, not a translated checkbox. Every visit happens in your language.
03
Same-day care is the baseline.
Calling for an appointment three weeks out shouldn't be the only option. Walk-ins are a real promise — held capacity, every day.
04
Continuity beats volume.
We'd rather know you well than churn through twice as many faces. The doctor who saw you last is the one who picks up the phone.

Why patients choose us

A different shape of primary care.

We are not a national chain, not a hospital outpatient department, and not a quick-stop urgent care. We are a small primary care office that runs at the pace patients actually need.
