Mark B. Berger, M.D.

Mark B. Berger, M.D. is President and Chief Medical Officer for Precision Pulmonary Diagnostics. He founded Precision Pulmonary Diagnostics in 2003 to pursue the goal of identifying and treating commercial drivers with sleep disordered breathing. Dr. Berger graduated with honors from Baylor College of Medicine and is board certified in pulmonary medicine, critical care and internal medicine. He has been active in the clinical practice of sleep medicine for many years and treats hundreds of new patients annually with sleep-disordered breathing.

Over the past three years, he has worked closely with Schneider National, Inc., one of the largest North American long-haul commercial carriers, in developing their sleep apnea program for drivers. This program includes the first ever fleet-wide screening of drivers for sleep apnea. His experience with Schneider National was recently reported as one of four "outstanding papers" chosen at the 2005 International Truck and Bus Safety and Security Symposium, sponsored by the Federal Motor Carrier Safety Administration and the American Trucking Association. Dr. Berger's approach to remedying the problems associated with sleep apnea in commercial drivers combines solid evidence-based medical research, with a unique sensitivity to the specific demands and requirements of the trucking industry.

Wendy Sullivan, RN

Wendy Sullivan, RN is Vice President of Project Implementation and Health and Safety Consultative Services for Precision Pulmonary Diagnostics. She joined PPD in October 2007 to fulfill her passion in improving commercial drivers' well-being, particularly through implementing integrated and comprehensive sleep apnea programs within the transportation industry. In her occupational medicine leadership role at Schneider National, Wendy was impressed with the high prevalence of sleep apnea within the fleet and its effects on a driver's health and safety. Between 2004 and 2007, she worked closely with Dr. Berger in developing the award-winning Schneider National Sleep Apnea Program. In 2007, this program was awarded the National Sleep Foundation Healthy Sleep Community Award and the first ever American Sleep Apnea Association Corporate Recognition Award. Additionally, Wendy and the occupational medicine team she led at Schneider National were awarded the Safety Presidential Award and the General Presidential Award in 2006.

Prior to her seven-year tenure at Schneider National, she was employed for 10 years by a large national health insurance company where she gained additional experience in human resources, disability, and other health issues. Her expertise is recognized within the commercial trucking industry where she has been a speaker at various conventions including the American Trucking Association, several state trucking associations, and the Society of Human Resource Management. She has had several published articles and interviews in Transport Topics, the Associated Press, XM Radio, and various local and state newspapers.

Wendy has been a Registered Nurse for 32 years and she continues to work part-time in direct patient care activities. As a nurse, she quickly realized that commercial drivers have unique needs and challenges and her passion for sleep apnea developed when she saw how many drivers were affected by, or at risk from, this life-threatening condition. Wendy says: "My goal is to have drivers improve their health and safety and get them back home to their families. Many drivers do not realize they have signs and symptoms of sleep apnea. The symptoms are often masked by excessive caffeine use, cigarette smoking, 'stackers', and other efforts on their part to stay awake. I continue to hear from many grateful drivers who cannot believe how much better they feel and thanking me for encouraging them to participate in the sleep apnea program."
