Hear From Our Friends:
Lisa and her staff are truly exceptional therapists! It starts with being greeted with a big smile from Jasmine, the proficient receptionist. Patrick warmly greets you next, and leads you through exercises, checking back regularly to see that you are okay. Lisa does thorough evaluations of your condition, and designs a treatment program that generates noticeable improvement early on. She knows just how much pressure to apply, and where. Lisa is a warm hearted, truly gifted therapist, and very creative in modifying exercises as needed. Troy is another very good hands on therapist, and is also a good listener, as the whole staff is. Carlos is very quick in assessing and providing what is needed to improve limited function in a hand, and loves to laugh. Shelby is energetic, quick to smile, and also gets good results with her hands on treatments and exercise coaching. I have been a client of Desert Hand & Therapy for 3 different injuries to the back, body, and hand. Each time I have regained full function and become pain free. They are the best in their field, and I am truly grateful!
