Dr. Mallory Feinberg-Hewitt, DC, Webster Certified

Dr. Mallory was born and raised in Southern California. She grew up participating in a variety of sports from soccer, to cross country, to synchronized swimming. While attending the University of Colorado at Boulder, Dr. Mallory suffered a spinal fracture, and after several days in the hospital she was given pain medication and a back brace to wear for three months. Although her spine “healed”, she was still in pain and unable to live the active lifestyle that she was used to. Through chiropractic care, core strengthening and functional exercises, she fully recovered from the injury and completed her first triathlon eight months later. Dr. Mallory went on to complete the four-year chiropractic program at Southern California University of Health Sciences.  Dr. Mallory is a Webster Certified practitioner which  involves a specific sacral analysis, adjustment and related soft tissue release to be used throughout pregnancy.
In 2009 Dr. Mallory started her practice in Long Beach and worked in a busy family and sports medicine practice gaining further experience and training in the treatment and rehabilitation of all types of injuries and conditions. In 2012 Dr. Mallory and her husband, Dr. Jack Hewitt, opened Kinesis Chiropractic and Physical Medicine.
In her free time Dr. Feinberg enjoys practicing Bikram yoga, crossfit, trail running, hiking and traveling.
