My patients should know that I am passionate about what I do! I strive to provide the best care possible, starting before the actual visit. I thoroughly review my patients’ charts so I can come into the visit with an understanding of their history, prior testing/procedures, and their current treatment plan. By going into the visit with this knowledge and carefully listening to my patients during their visits, I can ensure that they receive the best and most up-to-date care. I believe that each patient plays an important role in their health journey, and it is important to take the time to educate my patients to ensure they understand their condition and why I am making the recommendations that I am. I am originally from Wisconsin and moved to St George in 2021. When I'm not at work, I enjoy spending time with my husband and two kids, hiking, biking, exploring national parks, spending time outside, taking pictures, traveling to Wisconsin to visit family, playing board games, and doing puzzles.

I am not a medical doctor. I am not “like” a physician assistant. I am a NURSE with an advanced degree allowing me to be your primary care provider. With years of bedside care behind me, I realized education was standing in my way of doing more for my patients! Yes, I can diagnose, treat, order, and prescribe but more importantly I will talk with you, give you a hug when life gets too hard, play peek-a-boo with your kids, cry with you, stop and listen, be your biggest cheerleader, mourn with you, and treat you as a real person and never a number. I believe sincerity and compassion should remain in medicine and I enjoy building lasting relationships with my patients and their families. I was born and raised in Davis County, Utah where I had also been working in hospital medicine. I recently moved to Saint George at the end of July 2019. I currently live in Little Valley.
