Professional Experience

  • Private practice in Waukesha, 1975 to present. . . Upon graduation from Logan College of Chiropractic, my wife Roseanne and I moved to Waukesha, Wisconsin with our one-year-old son, P.J. We opened the Bluemound Chiropractic Life Center on January 15th, 1976. The practice grew to 100 patient visits per day within one year. Over the next several years an associate was added and the practice grew to 500 visits per week. The practice became a Renaissance based practice in 1978 when new patients were accepted only after attending pre-care classes. The practice began to start 100 new patients per month from direct referrals and we quickly reached capacity. The practice has sustained itself as a non-advertising, direct referral, family-based, non-therapy practice for 39 years. Currently, the practice is called Heffernan Chiropractic Clinic. We have two full-time chiropractors. The practice integrates segmental specific chiropractic adjustments delivered using the X.Y, Z coordinate system. Adjustments are integrated with rehabilitative spinal exercises, theraball exercises, and yoga classes.
