Morgan Dombroski

BSN, RN

Morgan was born and raised in California but has lived in Arizona for 10 years. She received her Associate’s degree from Scottsdale Community College in 2017, and graduated from NAU in 2018 with her Bachelor of Science in Nursing. She has also been a member of the American Holistic Nurses Association since 2019. She has 15 years in the medical field, starting as a phlebotomist and then working her way to a CNA before becoming an RN in 2017.

Morgan began her career as an RN at St. Joesph’s Hospital & Medical Center on the Acute Neuro/Telemetry unit then transferred to the Medical Surgical & Telemetry Float Pool, where she gained experience on many different units in the hospital.

Morgan’s goal as an RN is to help patients maximize their well-being by taking healthful action in every area of their life. Her primary concern is to cultivate a professional environment where each patient feels comfortable, receives focused attention, and is given exceptional care.

In her free time, Morgan loves traveling to new places, doing hot yoga, hiking, reading, listening to podcasts, and spending time with her husband and her two beautiful children and their dogs Leelo and Koufax. Her favorite memories are camping with her family in Idaho, swimming in the lake, and telling stories around the campfire.

Stuart grew up in a small forested village in Germany where he discovered his love of the outdoors. At age 20, he joined the U.S. Army and shortly after deployed to Iraq in 2006.  After his military career, he began studies at Embry–Riddle Aeronautical University in Florida while working for the DoD (Department of Defense) for 7 years.  Upon graduation, he accepted a job with Boeing, so he moved to the Phoenix area; here, he met his wife, with whom he created a naturopathic medical clinic, Nascent Health.
