About Westport Pain & Performance

Medicine works differently when your physician has time to know the full story.

Westport Pain & Performance was built around a straightforward idea: fewer fragmented appointments, more clinical context, and a relationship that can connect pain, performance, recovery, and long-term health.

A physician-led practice with one accountable point of view.

Dr. Adam Nessim practices Physical Medicine & Rehabilitation with a focus on pain, sports, regenerative, and longevity-oriented care. His model combines diagnostic reasoning, procedural expertise, and ongoing health optimization rather than treating each concern as a separate transaction.

Patients are given time to explain what is happening, why it matters, and what they hope to regain or improve. The goal is a prioritized plan that is clinically grounded, realistic, and easy to act on.

The practice model

What high-touch should mean in medicine.

Premium is not a dark color palette or a long menu of treatments. It is access, judgment, follow-through, and a process designed around the patient.

More contextSymptoms, labs, imaging, lifestyle, goals, and risk are interpreted together.
More timeVisits are designed for real discussion rather than a rushed transaction.
Clearer evidenceEstablished care is separated from options whose evidence remains limited or evolving.
More accountabilityThe practice helps coordinate the plan rather than leaving patients to connect the pieces alone.
