5 /5 Alejandro R Zamora: David quenzer is an amazing therapist who has helped my mother very much over this year. Hes so professional and kind. My mom had a stroke and was unable to move on her own or do basic things by herself. Thanks to David’s hard work and patience with her, she has been able to become even more active than before even her surgery. She has lost aswell around 150 pounds with the workout and flexibility routines he tells her also to practice at home. She can now even go down and up stairs, jump, and on the way to run! Thank you David!
