Dr. Nainani earned an MD degree from Loma Linda University, where she also received a Master of Science degree in biochemistry. Her residency was completed at the Medical College of Georgia, located in Augusta, Georgia, in 2006.

Embracing her alma mater's philosophy, "to make man whole," Dr. Nainani emphasizes care of the whole person. This philosophy helps her to see each patient as a unique individual and guides her in seeking a comprehensive approach to health, whether it be caring for a pregnant patient in prenatal care and delivery or taking care of gynecologic problems.

Stephanie and her husband, Greg, are outdoor enthusiasts and are anticipating the beautiful Walla Walla weather. Greg Nainani has also joined the team at Adventist Health/Medical Group as an administrative resident for finance.

Dr. Snider is fluent in Spanish and speaks conversational German and Italian.

Before becoming a physician, Dr. Snider enjoyed a successful career in bioengineering. In his free time he served as an EMT and volunteered at Mission Bay Hospital in San Diego-experiences that convinced him to change career paths and go to medical school. He continued volunteering while attending medical school, traveling to the Red Cross Hospital outside of Guadalajara, Mexico on the weekends and found himself doing everything from sewing up wounds from bar fights to delivering babies. Dr. Snider and his wife, Andrea, recently welcomed their first child--a girl--and are enjoying the adventure of parenting.
