  • Sri, Sunnyvale
    COR is without a doubt one of the best things I have done for myself. I started COR 5 years back and since then I have pushed myself both physically and mentally to limits I could not imagine and I certainly have reaped the rewards. Dr. John, Chris and Mike are amazing, they encourage you every step of the way and they are so passionate in everything they do. With their help I am constantly re-evaluating and re-setting my goals to lose body fat and train harder to do events like Spartan race and half dome hike and marathons. With their dynamic and personalized workouts I have become stronger, more energetic and able to reach my goals, they know how much to push, how to motivate & educate you on nutrition. Above all, COR is a community of people who support and encourage each other. It is fun to be part of COR group. Over the years this group have become my best of friends and part of my family. I recommend COR to anyone who wants to take the first step towards fitness or anyone who wants the challenge and push their limits, COR is a perfect place for you, where you are heard and helped by experienced coaches to set goals and successfully do it.

  • Kaila, Santa Clara
    I'm from Chico, California. I got to school at Santa Clara University where I'm studying marketing and retail studies. Some of my interests are hiking, kayaking, and watching Survivor. I love fitness because I love the feeling it gives me after. I always did distant running throughout high school and some through college. After I got injured, I searched Physical Therapy clinics near me. Once I came here, I loved how nice and personal everyone was and how they listened to me about my injury. In the storm term, I just want my leg to feel better so I can start running again to clear my mind. In the long run, I'd love to continue to do marathons again.

    Dr. John Mullen and everyone in the office is very attentive and helpful in providing effective physical therapy rehabilitation treatments and exercises. Being an avid swimmer, I'm especially thankful for Dr. Mullen's knowledge and experience with shoulder ailments, and the relief I have gained as well as new strengthening techniques. I highly recommend COR!
