Board Members

RiverStone Health Foundation is governed by a diverse Board of Directors.  In addition to the Board’s governance responsibilities, they also work to ensure that financial resources are available to fulfill its mission of Improving Life, Health and Safety through Philanthropy.

The Board is representative of our generous community.

Mary Hernandez

Career: Principal/Owner of Invisage Consulting since 2012
Year joined board: 2011
Why you’re committed to serving on the board: I’m committed to RiverStone Health Foundation’s role of providing financial support for the myriad of programs that RiverStone Health maintains to keep our community healthy, and the healthcare it makes available to our local citizens who would otherwise not have access to healthcare. It will take continued advocacy on behalf of RiverStone’s patients, clients and the general public to help policymakers and voters visualize the importance of sustaining public health programs and clinics. RiverStone is a crucial healthcare leader lending its voice for the community at-large as well as the disenfranchised.

Alex Martin

Career: AVP & Commercial Loan Officer Vice President of Accounting, WMK & Western States Steel Erection Co’s
Year joined board: 2014
Why you’re committed to serving on the board: I believe that RiverStone Health is an avenue for individuals to create better lives for themselves, their family and their community.  Not everyone has the financial wherewithal to receive healthcare, but this should not exclude them from access to care.  The Foundation supports a system where one gets more than just a checkup, they get a holistic approach that includes the education needed for a better life.

Type 2 diabetes prevention and prenatal care are two areas in which education could help people make healthier choices.

I think a major issue for consumers on the horizon is healthcare costs in general. The way the healthcare system is set up, consumers are voicing their concerns on the price of healthcare, but operating a healthcare facility is not inexpensive. The United States will try to find the “happy medium” between cost and operation of a healthcare facility, but it will be too difficult to solve. We are already seeing independent healthcare facilities merging with major hospitals to reduce operating costs so the focus can be on the patient which should be the concern for any healthcare facility.

Career: Retired Vice President and CFO, Stillwater Mining Company

Why you’re committed to serving on the board: My wife and I share a long-standing interest and involvement in assuring the excellence of healthcare in the communities where we have lived. Having resided in Yellowstone County for more than 12 years, we have been impressed with the quality of healthcare facilities and the dedicated service of healthcare professionals in this area. It is my hope that through service on the RiverStone Health Foundation board of directors I can help ensure that the high standards of professional care we have experienced will be continued and strengthened into the future for all residents of this community.

Joan M. Thullbery, RN

Career: Director of Acute and Ambulatory Clinical Informatics, St. Vincent Healthcare
Year joined: 2010
Why you’re committed to serving on the board: I’m committed to serving on the Board of Health because it gives me an opportunity to serve a Community Health Center that innovates on behalf of their patients. To be able to innovate on behalf of their patients, RiverStone Health must also innovate on behalf of their staff and providers. RiverStone Health’s ongoing work toward quality care ensures that their medical residents get the very best experience possible as they grow into being providers. By being early adopters of things like Patient-Centered Medical Home and other quality initiatives, RiverStone Health has transformed itself from a small Community Health Center to being a multifaceted community care organization. It is exciting to be a small part of this work.
