Undergraduate: Miami University - B.S. Zoology , B.A. Classical Humanities
Medical School: Western University of Health Sciences

Hi! I was born and raised in Columbus, Ohio, and I am so glad to have made it to the central coast of California for residency. I am passionate about reproductive justice and access to quality care and chose Marian because of the opportunity to serve an underserved population. I am currently working on a project to implement outpatient labor induction here at Marian to improve patient outcomes and patient experience. In my free time, I like to hike with my dog and my partner, surf, peruse farmers markets, and see live music.

Hi, I’m Allie! I grew up in Mountain View, CA. Prior to medical school, I coordinated clinical research in adolescent eating disorders, trained in massage therapy, and volunteered in community-based Sex Education for CA public schools. I attended medical school in Yakima, WA, and completed my clinical training in Portland, OR. My interests include Family Planning, mental health, OMT/massage, cooking, and pugs. I’m so excited to be a part of the supportive and kind OB/GYN team at Marian, and to have the opportunity to watch our residency program grow.

Undergraduate: Loyola Marymount University (B.S. Biochemistry and B.A. Spanish)

Hello! My name is Stephanie! I was born and raised in sunny Los Angeles, California. After spending all of my life in Southern California, I am so excited and beyond grateful to start this next chapter of my life on the Central Coast. During my time rotating at MRMC as a 4th year medical student, I was drawn by the diverse patient population, the dedication of faculty to resident teaching, and the leadership opportunities that exist in joining a new residency program. My interests include high-risk pregnancies, improving access to reproductive health services, and working for health equity. In my free time I enjoy watching sports (Go Lakers!), attending concerts, traveling and spending time with my family.




Chris Carls, DO

Undergraduate: Vanguard University (B.A. Religious Studies)
Medical School: West Virginia school of osteopathic medicine

Hi all! I am from Colorado but I’ve spent a great deal of time in Southern California. I have family in both northern and southern California which is what drew me to the Central Coast. I really enjoy this residency program and I think I am receiving excellent training. I think it’s the perfect Community hospital-based OB/GYN program. I am very happy to be a part of the first class of this residency and I feel a sense of honor in being part of establishing this program. Outside of residency I really enjoy hanging out with my family and kids. I am married and I have four children. We like to hike, go to the beach, play at the park and just do family things. Personally I enjoy playing guitar, reading and running.


Rebecca Ruebsamen, DO

Undergraduate: UC Berkeley (B.S. Nutritional Science, emphasis in Physiology and Metabolism)
Medical Education: Western University of Health Sciences 

Hey guys! I’m Becka and I am from Ventura, California. I love living on the Central Coast of California and truly love the people I work with here at Marian Regional Medical Center.  As a fourth year medical student, I rotated here. While I was here, I had such great experiences working with the faculty, nursing staff, and getting to know the patient population in Santa Maria. I am passionate about family planning and am considering pursuing a fellowship in this area. I am also interested in advocacy and as such, I hold a position on ACOG as our Section 4 Junior Fellow Chair. I love traveling, hiking, going to the beach, and corgis, although I do not have one sadly. I am a diehard Cubs fan and sports lover in general.


River Saul, DO

Undergraduate: University of Massachusetts - Boston (Biology), Wellesley College (Neuroscience)
Medical Education: Touro University - California 

I was raised in Minnesota, schooled in Boston, Sacramento and SF Bay Area, and I found my home here at Marian Regional Medical Center. The faculty, staff, and patient population here is truly exceptional, and I am overjoyed to call this nook of paradise my home. As a member of the first OB/GYN residency class at Marian, I had the privilege of early surgical exposure and responsibility and have focused on developing my skills in that area. Prior to medical school, I was a sexual health educator, an international resident artist, researcher in neuroscience, and a video gamer. I am passionate about reproductive justice, global health and wilderness medicine. I keep balance in residency with multipitch rock climbing in places like Yosemite, Joshua Tree, and our local Bishop’s Peak.
