Whaley received a Master of Public Health from the University of Alabama at Birmingham and a post graduate certificate from Harvard Business School, Executive Management Program. She graduated from Oakwood College in Huntsville, Alabama, with a Bachelor of Science in Biology and a minor in Chemistry.

John departed from Donor Network West in 2015 to serve as Director of Organ Clinical Operations at OneLegacy while earning his Master of Business Administration from Washington State University. Fortunately for Donor Network West, he returned in 2018 as Regional Director for Nevada. John’s region was the top performing region by metrics in 2019 as he helped build a culture of donation along with leading the efforts in transitioning all service area hospitals in Northern Nevada to Donor Network West as a single provider for both organ and tissue services. He assumed the role of Vice President of Organ Operations near the beginning of 2020.

As a life-long learner, John has returned back to school in pursuit of his Master of Science in Nursing degree to obtain his Clinical Nurse Leader (CNL) credential at the University of Nevada, Reno. His experience, education, and leadership helps Donor Network West to be one of the nation’s top-performing organ procurement organizations.
