    I've had it with Quest Diagnostics. I made an appointment with the Quest Lab on Valencia Street on Nov 7. I received a confirmation email with a QR code moments later, as usual. Today (Nov 25) I logged in to my Quest account and discovered there is no appointment scheduled. Quest Customer Support was no help at all. I searched the Quest locations and it turns out that for some reason the Valencia Street location is closed until 12/31, but they did not bother to inform customers who'd scheduled appointments. Use another service, Quest does not deserve your business.

    It's super clean inside

    I have trained with Rick for over 7 years. I started with him to help the pain from pinched nerves…read morein my neck from occupational demands. He has expertly trained me to strengthen the posterior muscles in my back and neck, resolving the pain, and preventing it from recurring for 6.5 years now. I don't worry about that hazard anymore, while my colleagues continue to suffer. When I met Rick, I had not anticipated how holistically he would change my life for the better. He discusses his latest learnings (he's always learning) each session with such enthusiasm and insight, its remarkably infectious. Not only has he helped my physical well being, he has been a spirit guide for mental, psychological and interpersonal well being as well! Throughout our visits, he has transformed my understanding of nutrition, wellness and my relationship with food for the better. I feel empowered and equipped to make the right life and food choices to fuel my body to feel a decade younger. Rick has become a dear friend and essential element to my quality of life. He has transformed my life for the better, during our fun and entertaining sessions. No matter how tired or spent I feel when I arrive to a session with Rick, I ALWAYS feel better when I am done than when i started: physically, mentally, emotionally and holistically! Investing in myself with Rick has been the best money and time I have ever spent. Naveen Chandra, MD

    Listen, it's very simple here. If you truly want to be healthy, take direction from an expert and…read morejust work with Rick. I can't think of a high enough recommendation for him. Objectively, I'm physically stronger and the healthiest I've been in my adult life right now. I wouldn't be able to say that if I hadn't spent most of the last two years working with Rick. Apart from reversing my hypertension and stabilizing my (diabetic prone) blood glucose, I have also uncovered my self-limiting beliefs about who I could be. I feel comfortable and confident walking into my gym and putting together my own strength routines based on the impeccable guidelines and guidance that Rick has given me. He's a patient teacher, a steady comrade, an enthusiastic student of life, and the best choice you could make for optimizing your current fitness goals, or turning your health worries into a success story.
