Pacific Hyperbaric & Regenerative Center

The PHRC Team

Expertise United by a Common Purpose

At Pacific Hyperbaric & Regenerative Center (PHRC), patient care is guided by a multidisciplinary team of physicians, specialists, certified hyperbaric professionals, and healthcare practitioners who share a common commitment—to provide clinically guided, patient-centered care.

We believe that meaningful outcomes are achieved not through a single treatment, but through the integration of medical expertise, evidence-informed therapies, and personalized care. Our team works collaboratively to develop treatment plans aligned with each patient's health status, goals, and individual needs.

From Hyperbaric Oxygen Therapy and Regenerative Care to Nutrition, Dermatology, Acupuncture, and Self-Care services, every aspect of care at PHRC is delivered within a structured clinical framework designed to support recovery, function, and overall well-being.

Our HBOT Medical and Care Team

Our clinical support team — comprised of registered nurses, hyperbaric operators, our concierge, and housekeeping — works alongside our physicians and hyperbaric specialists to ensure that every patient receives attentive, safe, and consistent care throughout their time at PHRC. Trained in safe, ethical, and medical-grade hyperbaric operations, patient monitoring, clinical support protocols, and sanitation standards, they are the hands-on presence that makes every treatment session run smoothly and in a clean, well-maintained environment.

Beyond their training, what defines this team is their genuine care for every person who walks through our doors. Their work is guided by the same commitment that defines PHRC — that every patient, regardless of why they walk in, deserves to feel cared for, safe, and in good hands.

Our Aestheticians

Skin & Self-Care Specialists

Our aestheticians bring skill, care, and genuine warmth to every self-care and aesthetic treatment at PHRC. Working under dermatology physician guidance, they are trained in the treatments and protocols that define our Self-Care services — ensuring that every facial, skin, and aesthetic session is delivered with both technical precision and a personal touch.

But beyond technique, it is their attentiveness and warmth that patients remember most. They are the reason patients leave not just looking better, but feeling better.
