Founded by sleep specialist, Mark B. Berger, M.D., PPD is committed to the diagnosis and treatment of sleep apnea in commercial drivers/operators. Wendy Sullivan, RN 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. We are experienced sleep physicians and health professionals whose focus is on health and safety issues specific to drivers and their employers.

We provide effective screening tools, rapid diagnosis and treatment for drivers with sleep apnea. Effective sleep apnea treatment can deliver substantial savings in healthcare and safety costs for employers, and improve the health and quality of life for their drivers — while making roadways safer for all travelers.

As an industry advocate, we pursue an active role in the advancement of driver-related health and sleep disorder regulations.
