  • Lisa Pendleton

    Lisa Pendleton has been practicing massage since 2004, with a focus on the treatment of injuries associated with auto, work, recreation and home accidents. Her intuitive touch, coupled with her skill in using multiple massage techniques, has been shown to help reduce her clients’ healing time and increase function for acute and chronic injuries. Lisa uses a technique to “unhook” tight muscles in a virtually pain-free way. This is a preferred method with clients with head injuries, especially those with headaches, as it is so gentle. It has been shown to accelerate the healing associated with neck, back and head injuries in many cases. As the patient becomes more relaxed, she then integrates muscle release techniques and gentle stretching. Her treatment goals are to make sure her clients are comfortable, and in a safe and trusting space. Lisa is excited to align herself with Concussion and Whiplash Clinic and add additional skills to our health care team, so our patients can get the best care possible.
