About Us

We are a locally owned and operated clinic. Our therapist work where they live and we are committed to serving our communities.

How We Started


HIDEF was founded by physical therapist Zach Smith and personal trainer and nutritionist Mitch Harb. What started as a podcast and charity workouts to serve the community has grown to a multi location practice. The original idea of HIDEF was to bring all elements of health together as one combining physical therapy, personal training, nutrition, and mindset. Over the years we came to realize our true passion was a focus on physical therapy and the journey of creating a physical therapy clinic that included these elements.


Why is HIDEF Physical Therapy Different


HIDEF Physical Therapy is different from other clinics by how we operate. We schedule each patient with a 60 minute time slot and have a 1 to 1 care model. This means that at all times you will be with a provider in our clinic and will not be left alone to simply go through exercises on your own. Our focus is on quality. We provide extensive hands on techniques with manual therapy, joint mobilization, massage, and cues for corrective exercises. Our focus is on excellence.

How We Evolved Over Time


At first our company started as a mobile physical therapy company with in gym personal training and online nutrition coaching. Originally Zach was seeing professional athletes, many of them members of the Seattle Seahawks from their home. Helping them to manage in and out of season aches, pains, and injuries. The first location was opened in Seattle, WA in 2019 within Pandora Fitness. We quickly outgrew the space and transitioned to CrossFit Felix, where our clinic still lives today in the Belltown neighborhood of Seattle, WA. As our reputation grew, so did our company. We opened our first solo brick and mortar location in Bellevue, WA in August of 2021. Soon after we opened another in gym location in Renton, WA inside of one of the top gyms in the state, Vigor Ground Fitness and Performance. Today we have 3 practice locations in the Greater Seattle Area.
