Chelsie M. Word

PA-C, Certified Physician Assistant

Chelsie Word, Certified Physician Assistant, was born and raised in North Dakota. She moved to Northern Arizona after high school graduation and attended Northern Arizona University in Flagstaff, for her Bachelor’s Degree. Her focus was pre-med with a Major in Psychology

and Minors in both Biology and Chemistry. During her time at NAU, she met her future husband, Jon, who works for the US Forest Service. His work has lead them to many new places over

the past several years.

Chelsie moved to Northern California (40 miles south of Oregon) following college graduation and continued her pursuit in medicine by becoming a medical assistant. During this time she applied to Physician Assistant schools. She and her husband took a chance on a school in Henderson, NV and moved before getting accepted. Thankfully the move was worth it and she was accepted into Touro University’s program and obtained a Master’s Degree in Physician Assistant Studies.

Chelsie and Jon remained in the Henderson/Las Vegas area after school and Chelsie started practice as an Orthopaedic Spine PA. She quickly fell in love with specialty practice, specifically orthopaedics. Her husband’s job continued to progress, and the next move was back to Flagstaff, AZ where her initial medical journey began. Once again she ended up in Ortho Spine, but added on trauma as well. This expanded her knowledge and

was a great experience.

The next move brought Chelsie and her family to Northern Wisconsin, with employment in the Upper Peninsula of Michigan. Unfortunately, living in such a remote area, there was not an opportunity for much specialty practice, so Chelsie worked for a short time as an Emergency Medicine PA during night shifts, and then transferred to Family Practice/Urgent care position.

Her final move (well, maybe) in October 2017 brought her to the White Mountains of Northern Arizona with her current position at AZ Mountain Orthopaedics. She now has two beautiful children who are three and five years old, and still tolerates her “always moving” husband, Jon.

They feel very blessed to be here, and Chelsie enjoys being back in orthopaedics. Chelsie enjoys spending time with her family, traveling back to ND to see family and spending time on the lake she grew up on, beaches, road-trips, and also her dog, Maggie (the first child).
