Assistant Clinical Professor

David S. Grega is an assistant clinical professor for the Master of Health Services — Physician Assistant Studies and Master of Science — Family Nurse Practitioner degree programs at the Betty Irene Moore School of Nursing UC Davis. Grega brings to the program 40 years of patient-care experience and education. He is a board-certified physician assistant and spent the past 13 years in an orthopedic surgical practice in Sacramento.

Grega is a proponent of patient education and believes in educating providers in the “art of medicine.” He seeks to prepare primary care providers to develop, maintain and utilize fully the clinical and procedural skills within their scope of practice. He believes this will maximize access to efficient high-quality patient care as well as promote professional advancement and practice satisfaction.

Grega’s health care career began in the late 1970s as a firefighter and a paramedic. He completed his paramedic training at Stanford University Medical Center. He was a part of the early wave of paramedic services in Northern California and was involved in the implementation of paramedic services to both Santa Clara County and Petaluma Fire Department.

As an educator since the early 1980s, Grega served as both an advanced cardiovascular life support and pediatric advanced life support instructor, as well as an emergency medical services (EMS) trainer. Grega completed a teaching credential at UC Berkeley in 1985 while an instructor at Santa Rosa Junior College. He developed a training and recertification program for emergency medical technicians and served as an EMS training coordinator. This early involvement with teaching fueled his passion for education and training in health care services over the past 35 years.

The first 15 years of his physician assistant career were concentrated in primary care, including emergency medicine, family medicine, internal medicine and clinical research. After graduation, he joined an emergency medicine group in Seattle, as a staff physician assistant in a high-volume hospital emergency department. Grega’s family medicine experience included service with the Department of Defense as a civilian medical corps provider at Madigan Army Medical Center, in Fort Lewis, Washington. A significant part of his primary care experience also included medically underserved family practice and urgent care settings in the greater Seattle area, as a solo provider in free-standing clinics. Grega spent more than 10 years as a clinical research sub-investigator in a general internal medicine practice in Sacramento.

Grega graduated magna cum laude with a bachelor’s degree in Clinical Health Science at the University of Washington and completed his physician assistant training there in 1990 with the Medex Northwest PA Program. He received the 1990 Outstanding Student Scholarship from the University of Washington School of Public Health and Community Medicine. Later, he completed a physician assistant master’s degree with specialization in family medicine, with honors, from the University of Nebraska College of Medicine. He was awarded special recognition as a Distinguished Fellow of the American Academy of Physician Assistants (DFAAPA).
