Shannon, as you may call her, is a board-certified Family Nurse Practitioner and is passionate about living life fully and helping her patients to do the same. She has a special interest in pain management, holistic health, and educating patients.

She brings experience in intensive care, orthopedics, rheumatology, mental health, substance abuse, pediatrics, and dermatology to Arizona Pain Care Center.

Shannon’s education and training lends itself to utilizing a multi-modality philosophy, and employing creative approaches to understand, treat, as well as cope with pain. “I usually refer to it as a ‘piece of the pain pie’ in terms of what is causing pain and what can help. It usually requires understanding the slices of the contributing factors as well as the relieving factors.”  Other times it can be very simple; we understand what works and we can get it done. Shannon is great at making you feel at ease and will work alongside you, coordinating with our team of providers to navigate your individual treatment plan. 

Outside of the office, Shannon enjoys being a mother, travel, good food, photography, dance, and playing/singing music.
