We LOVE DV Therapy Palmdale! My son has Autism and gets Speech. He was getting Occupational Therapy services and has since graduated with the help of Ms.Alyah! Ever since he started there has been a HUGE improvement in his speech and fine motor skills. My child loves going to his therapies here and gets excited when he sees his therapists! It’s such a nice feeling knowing he likes the people there and wants to go back week after week. The staff here are very professional and you can see that they really care about your child. Ms.Amber is great and really takes in mind what my child interests are and turns it into speech opportunities! We are so grateful for all the amazing support from DV Therapy Palmdale!
