Janet Royal OTR/L


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.

Michelle started at Hands On Hands Rehab Center on April fools day of 2024.  We really were offering her the position but she had to convince her family that it wasn't a joke and glad that she believed us.  She runs our front office in the Laguna Hills office.  Michelle has worked in the medical industry since 2012 and brings with her a wealth of knowledge and experience in the healthcare system.  She speaks Spanish which is a huge asset for our patients being seen in Laguna Hills Office.  Michelle is a proud mother of 2 "sassy" girls.  They are her sunshine in a cloudy day, and the light of her life.  She loves to relax and lay out on the beach or pool, anywhere that has water, with one of her passions swimming.  Well Southern California is the place for her.
