David Pepper, M.D.

A student member of PSR, David Pepper M.D. attended medical school at the University of Iowa. After completing his residency at UCSF-Fresno in Family Medicine, in 1992 he joined the faculty, and in 1997 assumed medical oversight for the asthma education and management program.

Working with Kevin Hamilton, a noted respiratory therapist, the pair noticed that the incidents of asthma in the San Joaquin Valley were double the national rate. Hamilton and Pepper then formed Medical Advocates for Healthy Air (MAHA). Forging a unique collaboration with nonprofit groups, Sierra Club, Earthjustice and Latino Issues Forum, MAHA filed a series of successful lawsuits against the U.S. EPA seeking action on addressing the region’s asthma epidemic.

Working with legislator Dean Flores, MAHA began to curb asthma-related pollution. Laws are now in effect regulating open field burning, farm diesel engines and pesticide reporting. Dr. Pepper’s air pollution interests include: pesticides, diesel particulates, and vehicle exhaust. He commutes by bicycle whenever possible to do his part.

Dr. Pepper was vice president of his PSR chapter during medical school, and twice nominated for the UCSF Chancellors award for community services, after winning a similar award during medical school. From college to his practice, David has kept alive the PSR spirit.
