DR. GARRET L. WONG, PT, DPT, OCS, CSCS
FOUNDER AND PRESIDENT
Garret always had an affinity for sports and science so immediately selected a career that merged the two, helping others get back on their feet, to work, or out on the field. After achieving degrees from Loyola Marymount University and Samuel Merritt University, Garret has been able to serve in both neurological and orthopedic settings. He earned his Orthopedic Clinical Specialist certification and completed a residency in Proprioceptive Neurological Facilitation, which enhanced his efficiency in evaluating the underlying factors of musculoskeletal and nervous system dysfunctions. He is also a Certified Strength and Conditioning Specialist. Garret has been privileged to work at Davis and DeRosa Physical Therapy for more than a decade, a fixture in the El Segundo community.
“Over the years, I’ve witnessed the positive impact that physical therapy has on both patients’ and therapists’ lives. With Mana Mobile PT, I want to add and improve upon this experience by bringing it to real-world environments that allow patients and providers to maximize their potential. I look forward to continuing to reimagine what our industry can achieve and to welcome you into our Mana ʻOhana.”

DR. FEDERICO RAGAZZON, PT, DPT

He graduated from the University of California, Santa Barbara before completing the Doctor of Physical Therapy program at Mount Saint Mary’s University, Los Angeles.

TAMI CHANG, PT
Tami is an alumna from two of the most prestigious physical therapy schools, New York University and Robert Gordon University in Aberdeen, Scotland. Growing up, Tami was a family caretaker so choosing physical therapy as a career choice was a natural transition. Tami has extensive experience in Sports and Orthopedic Rehabilitation, as the longest tenured employee at Davis and DeRosa.
DR. CARLY STEENERSON, PT, DPT
Carly received her undergraduate degree from Grand Canyon University in biology with an emphasis in pre-physical therapy, then went on to receive her Doctorate of Physical Therapy from West Coast University in Los Angeles, CA. Carly has always wanted to work in healthcare. She loves to help people recover from injuries and return to their lives as quickly as possible, with less pain and greater mobility. In her free time, Carly loves hiking and spending time with family and friends.
DR. SETH POTTENGER, PT, DPT
Seth received his Bachelors of Kinesiology with an emphasis in Exercise Science from Cal State Long Beach, and his Doctorate of Physical Therapy from Azusa Pacific University. A lifelong learner, Seth is looking to acquire his Certified Strength and Conditioning Specialty next, to expand his knowledge in human performance. Seth was originally inspired to become a PT by his grandmother, who had Parkinson’s Disease. Blown away by her physical therapists and the powerful healing they provided, he watched as she and other patients worked to regain their mobility and physical functionality and knew what he wanted to do. Outside of work, Seth loves watching sports, trying out new restaurants, hiking, and watching movies.
DR. TROY DAVIS, PT, DPT
CO-FOUNDER
Driven by a motivation to help people recover from injuries, Doctor of Physical Therapy Troy Davis was drawn to his profession as a means to achieve that. The Long Beach native also knew he wanted to deliver care in a way that reflected his personal philosophy. “I wanted to develop relationships with people as I work with them to get them back to normal living,” he says. Troy sets a tone for a fun and relaxed atmosphere that is markedly different from traditional physical therapy clinics and is excited to expand these ideals to Mana Mobile PT.
CHRISTOPHER DEROSA, PT, OCS
CO-FOUNDER
Chris DeRosa says physical therapy was a logical career choice for him because making people feel good has always been a part of his DNA. “Following physical therapy allowed me to interact with people on a daily basis and provide them with help to feel better and live their lives fully,” he explains. He received his Bachelor of Science in Exercise Physiology in 1994 from Adelphi University followed in 1998 by his Bachelor of Science in Physical Therapy from the prestigious Robert Gordon University in Aberdeen, Scotland and began his career in New York City as a physical therapist. He is thrilled to be a part of Mana Mobile PT, where the care for people expands outside the walls of a clinic.
