Janet Royal OTR/L

founder

Registered Occupational Therapist Licensed

Janet has a new role at Hands On Hands Rehab Center. She has stepped down from the owner and now is a consultant and an assistant for Scott as he transitions to the ownership from one clinic in Laguna Hills to now all 4 clinics in Laguna Hills, Costa Mesa, Huntington Beach and Los Alamitos.  She is the original founder of the private practice which opened in 1981 and celebrated almost 43 years in private practice. Time has come for her to adventure into the next season of her life but not without passing the Paton to Scott and providing the smoothest transition with the highest level of continued care for our patients.  You might still be able to see her in Costa Mesa when she is not filming as an extra in her favorite T.V. series The Chosen. Check out seasons 3 in the feeding of the 5,000, Season 4 (not sure if she's on the cutting floor?) and Season 5 Holy Week, to see if you can find her. (She recommends you start with Season One first)  Check out where is she now in that folder above.
