About our Clinic

Our Mission

To provide the highest standard of care to every patient, every day. We use only proven leading-edge technology and carefully tailor your treatment for your condition with one-on-one treatment.

You can count on Oceanside Physical Therapy to deliver quality care because we set the highest standards for our Doctor’s of Physical Therapy.

Dr. Sean Mandell, DPT & Dr. Jacob Barrack, DPT are the founders of Oceanside Physical Therapy.Theyreceived their Doctorates at the University of St. Augustine’s in San Marcos, CA where they became great friends. After graduating they partnered up at Vista Physical Therapy & Rehab and created a successful private practice through quality, one-on-one therapy, inside the Wellness Center in downtown Vista. Their success allowed them to expand the business and open up a clinic in Oceanside at the request of many residents who were commuting to Vista in order to receive the high-quality care they had become accustomed to.


Sean & Jake understand that therapy needs to be one-on-one. They constantly hear clients’ experiences from other clinics of being left alone with a sheet of paper of exercises that they may, or may not be doing correctly. At Oceanside Physical Therapy, rehab is combined with education, nurturing relationships and a deep awareness of each client’s needs in a comfortable space.

One-on-one, individualized treatment to patients of all ages is always delivered by a licensed therapist in an environment built around each client’s needs. Recovering from an injury can be both physically and mentally challenging.

We believe that the support and camaraderie amongst our staff and patients, combined with our expert clinical knowledge and skills, makes your healing process enjoyable and extremely effective.

Oceanside Physical Therapy strives to bring you the best care possible, utilizing state of the art equipment, current evidence-based research, experience, and a team who cares about your health!
