Pam Schillar, a highly experienced Certified Registered Nurse Anesthetist (CRNA) relocated to Cave
Creek, AZ from Sandpoint, ID, bringing with her a wealth of knowledge and a deep commitment to
providing exceptional anesthesia care.
Pam grew up on a wheat farm in Ritzville, WA, a small community in Eastern Washington. She earned
her Bachelor’s Degree in Nursing from Eastern Washington University in May 1981 and began her career
as an RN at Sacred Heart Medical Center in Spokane, WA, initially working on a surgical floor. Pam later
transitioned to the Cardio-thoracic ICU, where she specialized in recovering heart and lung patients.
During this time, she had the opportunity to work closely with CRNAs who specialized in heart and lung
anesthesia, sparking her interest in furthering her education in this field.
In January 1991, Pam joined the United States Air Force as a commissioned officer. After two years in
the Medical ICU, she was accepted into the USAF CRNA program. The Air Force sent Pam to the
University of Texas Health Science Center, where she earned her Master’s Degree in Nursing with a
focus on anesthesia in 1996. Pam has been board certified since October 1996, and over the years, she
has gained extensive experience providing anesthesia services to patients of all ages in a variety of
settings.
For the past 19 years, Pam worked at Bonner General Hospital, a critical access hospital in Sandpoint, ID,
where she provided anesthesia care in a busy surgical services department. Pam enjoyed serving a tight-
knit community, caring for multiple generations of families. However, after years of long winters, Pam
decided to relocate to the Valley, a place she has always loved.
Pam is excited about the opportunities for both personal and professional growth in Arizona. In her free
time, she enjoys golfing, hiking, and taking in the breathtaking desert landscapes and sunsets. She also
enjoys the vibrant culture of the area, from local sports teams and spring training to excellent
restaurants and art and music festivals.
