Derin Allard, DO

Medical School: Western University of Health Sciences

Hi everyone, I’m Derin. I grew up in Huntington Beach, California and Istanbul, Turkey and went to undergrad at UC Irvine, majoring in political science. After completing a pre-med post-bacc program, I went to medical school at Western University of Health Sciences in Pomona, CA. I enjoy family medicine because of the broad scope of practice and the ability to establish long-term relationships with people of all ages. In my free time, I enjoy reading, photography, and all-things related to aviation.

Linda Baldwin, DO

Medical School: Western University of Health Sciences

Prior to becoming a physician, I was thriving in a career as an Outcome Analyst for Stanford Healthcare and as adjunct faculty for San Jose State University. Making a choice to make a major career change to pursue medicine has been challenging, but rewarding in so many ways. I chose to become a doctor of osteopathic medicine because of the Osteopathic Manipulative Medicine skill set that I would be able to use to help my patients heal. I chose to come to MRMC for my residency because of the culture of collaboration and respect, their Osteopathic Recognition, and their integrative medicine track. I felt that my skills as a physician would become well-rounded and well-honed through my training here. I am passionate about helping people achieve their optimal health and find their voice. I believe that building health partnerships with patients is a powerful tool to improve lives. In my spare time, I love spending time with my husband, five children, and three dogs. I love being near the ocean and the beautiful hiking trails all around us in the central coast.

I grew up in Santa Paula, California, two hours south of Santa Maria. I attended Thomas Aquinas College, where I met my wonderful wife, Francesca. Between undergrad and med-school I worked a number of jobs: construction, beach lifeguarding, football referee, medical scribe, and wilderness EMT. Then in 2015, my wife and I and our two children moved to Chicago to attend Loyola Medical School, and when we came back to California in 2019, we brought a third child with us! I love the variety I see working in Family Medicine, and in my off time I enjoy bike riding, surfing, spearfishing, SCUBA diving, camping, painting, playing guitar, motorcycling, reading, building model airplanes, board games, carpentry, and family time.
