Our Approach

Medicine practiced at its
highest expression.

Cellula was conceived for a singular purpose: to offer the world's most discerning patients access to a level of regenerative care previously unavailable in a private clinical setting. Dr. Castillo brings over two decades of combined orthopaedic and aesthetic medicine experience, recognized by the American Arthritis Association in the specialty of Regenerative Orthopaedics.

We do not offer surgical intervention. We do not operate within the constraints of an insurance-driven system. What we offer is time, precision, and biology — applied with an artist's eye and a scientist's discipline.

Every patient who enters Cellula is treated as a singular case. Your anatomy, your biology, your goals — studied, understood, and addressed with a bespoke protocol developed exclusively for you.

Our Areas of
Expertise

Six Core Disciplines
01

Regenerative Orthopaedics

Non-surgical treatment of joint degeneration, arthritis, and cartilage loss in knees, hips, shoulders, and the spine — using the body's own regenerative capacity, amplified by precision biologics.

02

Soft Tissue & Sports Recovery

Advanced biologic therapies for tendon tears, ligament injuries, muscle repair, and chronic musculoskeletal pain — returning elite athletes and active individuals to full performance.

03

PDPC+ Biologic Injections

Placenta-Derived Protein Complex — a concentrated formulation of over 8,000 secreted proteins, growth factors, and exosomes that instruct your existing cells to rebuild and regenerate from within.

04

Exosome Therapies

Targeted exosome delivery — chondrocyte-lineage for joint restoration, skin-lineage for regenerative aesthetics — designed to reboot cellular behavior and silence chronic inflammatory cycles.

05

Regenerative Aesthetics

Cellular renewal for the face, hair, and skin. Hair restoration, skin rejuvenation, scar remodeling, pigmentation correction, and anti-aging protocols — without surgery, without downtime.

06

Anti-Aging & Longevity

A comprehensive regenerative longevity program integrating biologic therapies, inflammation management, and cellular health optimization — for patients who refuse to accept the conventional pace of aging.

Investment & Pricing

Transparent.
Exceptional. Precise.
