Who We Are


Dan Dumas Pleasanton and Sacramento Co-Founder & Chief Executive Officer

Annabelle Constantin Pleasanton and Sacramento Co-Founder & CFO

On June 3rd, 2005 Dan was hit by a wave while vacationing in Maui and broke his neck, leaving him with a C-5 incomplete spinal cord injury. He spent three months in the hospital after fusing his cervical vertebrae. Dan was told repeatedly that would never walk again, let alone move anything below his level of injury.

Dan and his wife, Annabelle, refused to believe this prognosis and began searching for alternative therapies for spinal cord injuries. One week after being discharged from the hospital they moved to Southern California to start an intense exercise-based recovery program. Dan began working out two hours a day five days a week. Dan saw tremendous progress within the first couple months and by the sixth month mark, Dan took his first steps in a walker. By the end of his program, Dan was no longer using a wheelchair, and walked with a walker or crutches full time.

Dan and Annabelle decided they wanted to create an opportunity for individuals with spinal cord injuries to participate in an aggressive therapy program without having to re-locate. Dan and Annabelle opened SCI-FIT Pleasanton in 2007 and have been in integral part of the business operations of the company. In 2014 a second location was opened in Sacramento making this program available to more people with neurological disorders in Northern California.
