A native of Oregon, Tina’s career has taken her to many different parts of the US. After graduating from the University of Oregon with a major in Planning, Public Policy, and Management, Tina moved to Washington, DC to gain work experience with the National Association of Public Hospitals. There she learned about the impact of the AIDS epidemic on the nation’s safety-net hospitals and participated in research on the use of emergency rooms for non-emergency health care.

After being awarded a Woodrow Wilson Program in Public Policy and International Affairs Fellowship, Tina earned her master’s degree in public management and policy from Carnegie Mellon University. Her focus on policy analysis prepared her for the exciting opportunity to work in the White House as a budget examiner in the Office of Management and Budget. There, she worked with federal budget appointees, cabinet members, and heads of agencies to formulate Public Health Service budgets and policies at the national level.

Future work introduced Tina to the field of civic engagement. She was proud to spearhead a research project working with high school teachers and students to teach the skills of public deliberation. She also enjoyed traveling around the country to moderate public forums and to teach civic engagement and public deliberation skills to locally organized groups. She was invited to be a guest instructor at Public Policy Institutes in Cincinnati, New York, Oklahoma City, Portland (OR), Philadelphia, and State College, PA. She also organized training events focused on equipping local leaders with the skills to convene and moderate public forums.

After the 2008 economy forced many people to reexamine their employability, Tina chose to add a Master of Accountancy to her credentials. She leveraged her policy and accounting skills to work in a number of fields including non-emergency medical transportation, telecommunications, water related consulting, and public utilities. During this time, she returned home to Portland.

After a brief stint with New Avenues for Youth, Tina decided to redirect her career path back to public health and was delighted to be selected to fill the Finance leadership position at Outside In.
