Mr. Clark has been active in clinical light applications since 1988. Pat moved from his first administrative and clinical exposure of laser use and control at the University of North Carolina Memorial Hospitals in Chapel Hill, North Carolina to being a member of the team to first accomplish and teach routine laser laparoscopic cholecystectomy in several Northeast states. A Texas native, Pat returned home in 1992 to be selected as the founding director of the laser program at the University of Texas Southwestern Medical Center at Dallas and the allied hospitals. In that position he refined a teaching and administrative process that included the control of some 117 laser and light sources in a myriad of applications and a recurring education process for physicians, residents, nurses, and paramedicals. Numbers of internationally known facilities and organizations call upon Pat to assist in development, testing, application and safety of light on tissue worldwide.

Pat has direct experience in complete hospital programs, outpatient and freestanding surgery centers, the beginnings of office and spa applications, and the development of light applications for nonprofessional and home use. His commercial experience includes being Vice President of Clinical Affairs and Product Development for both a national publically held mobile laser-surgical services company, Medical Alliance, and with the device division of an international pharmaceutical company, ICN. Often called upon by laser manufacturers and having given over 400 clinical and lay lectures in the last 20 years, Mr. Clark brings a world of experience to the laser industry.
