David Gardner, DO

Caldwell Program

David Gardner was raised in a small rural community in Northern California, the eldest of four kids. His father worked as a firefighter, and from a young age this inspired him to pursue a career in public service. After turning 19, David spent two years in Mexico as a missionary; this is where he first recognized major health disparities in both urban and rural communities and his desire was born to become a medical provider.

After returning home from Mexico, David met his amazing wife Katie. Both graduated from Brigham Young University-Idaho and moved to Arkansas for medical school New York Institute of Technology College of Osteopathic Medicine. Two cute kiddos later, they are ecstatic to return to Idaho to be trained by Full Circle Health‘s Family Medicine Residency of Idaho program.

David chose family medicine because of its broad training and the ability to practice in a limited resourced environment. Caring for patients who may have limited access to specialists is important and a passion of his.

In David’s free time he loves; fishing, hunting, backpacking, playing video games with his brothers, and dabbling in an array of sports. He’s beyond excited to return to Idaho; getting some of the best rural family medicine training this country has to offer.

Aryan Sharif, DO

Born and raised in the Silicon Valley of California; Aryan Sharif MD realized at a young age that the culture of a tech-centered community wasn’t for him. He had the chance to explore a number of different communities in the state of California. After moving to almost a dozen new cities, his family finally settled in Berkeley. Residing in farming communities in California and joining numerous volunteering efforts in rural communities, both domestically and internationally, Aryan noticed some of the unique challenges associated with living in the countryside.

This lead to his passion for increasing healthcare accessibility in rural communities, especially with Latinx individuals. As a result, this guided him to pursue his medical education at A.T. Still University in Arizona. The time with the Full Circle Health family will help him accomplish these goals (and have fun doing it!).

While Aryan can find something enjoyable about almost anything, some of his favorite hobbies include rock climbing, playing board games, and chasing sunsets!

Chelsey McCoy, MD

Caldwell Program

Chelsey grew up on a dairy farm in Melba, Idaho until age fifteen. It was then when her family moved to Haiti to do mission work with Maranatha Children’s Ministries. Upon graduating high school, she came back to Idaho where she attended the College of Idaho in Caldwell. There, she majored in biology and minored in chemistry. Concluding her studies, Chelsey then spent two years on the Oregon coast attending Bible school while preparing for medical school. 

In 2015 she made the move to the Dominican Republic to attend the Universidad Iberoamericana School of Medicine, graduating in November 2020. She then spent most of 2021 working and obtaining clinical experience in Oregon, Nebraska, Illinois, and rural Pennsylvania. This experience led her to prepare for the residency application process and was matched with the Caldwell program at Full Circle Health

Chelsey’s clinical interests are around bringing quality healthcare and education to underserved communities in rural America and the developing world. Her years in Haiti and the Dominican Republic have given her passion for humanitarian work and learning about other cultures and languages. She is excited to be back on her “home turf” and receive the broad-spectrum training a rural family residency provides. 

In her free time Chelsey enjoys spending time with friends and family, being outdoors, chasing sunsets, reading novels, playing sports, and dabbling with watercolors. 

Mariellen Van Nieuwenhuyzen, MD

Caldwell Program

Mariellen was raised on a small family farm in Northern California. She grew up actively involved in her family’s beekeeping business, as well as working in the almond orchard and raising sheep. Mariellen spent much of her youth caring for her mom who is severely disable by multiple sclerosis.

These experiences; as well as pursuing her undergrad in small-town Iowa (at Dordt College), running the family farm with her brother after college, and frequently spending time in Alaska and other rural communities, encouraged her to combine her strong love for agricultural/farming communities with medicine. She was fortunate to be part of a rural medicine training program at the UC Davis School of Medicine. This program let her explore and serve several smaller communities throughout the state. She is excited to continue exploring rural medicine during her time at Full Circle Health‘s Caldwell family medicine residency program. 

She and her husband are sad to be leaving behind many dear friends (and lots of good desert OHV riding and camping) at their current home near San Diego. But they are eager to build new community and friendships as they make southern Idaho their home. When she has free time, Mariellen loves spending time with her husband and family (especially holding baby lambs or going for runs on her family’s farm), exploring and enjoying the beauty of God’s creation, reading good books, dabbling with creative and expository writing, fellowshipping with her church family, and visiting the many wonderful friends she and her husband have been blessed with.
