Alysa was born and raised in Wyoming, where she developed a love for the outdoors and nature. In 2016, she made the life-changing decision to move to Alaska, a place she now proudly calls home. Alysa's educational journey began with obtaining an associate degree in exercise science, followed by a bachelor’s degree in psychology. After working in the psychology field for a few years, Alysa decided to pursue her passion for healthcare by obtaining a bachelor's degree in nursing from the University of Wyoming in 2013.


Alysa started her nursing career at the Wyoming Medical Center, where she initially worked in the neurology/stroke unit before transitioning to the emergency department. She spent a decade working in the high-pressure environment of the emergency room, with 7 of those years being at the Providence Alaska Medical Center.


During her time in the ER, Alysa recognized the critical need for patients to receive better primary care services. Motivated by this realization and desire to make a positive impact in her community, Alysa decided to further her education and training. In the summer of 2022, she graduated with her master’s degree in nursing and became certified as a Family Nurse Practitioner.


Alysa's dedication to providing exceptional healthcare continued as she joined Moose Creek Medical Clinic in 2022. Alysa provides comprehensive and compassionate care to our patient population. She is committed to making a difference in the lives of her patients. Alysa firmly believes in a holistic approach to healthcare, focusing on not just treating symptoms but understanding and addressing the underlying causes of illness.
