Gina Upchurch, RPh, MPH, Founder & Executive Director

Gina was born in Durham and raised in Reidsville, N.C. She earned her Bachelor of Science in pharmacy and her master’s degree in public health at UNC-Chapel Hill. She also completed a residency in geriatric pharmacy practice at UNC-CH. She remains as adjunct faculty with both schools. Between degrees, she served as a U.S. Peace Corps volunteer teaching science in Botswana. As part of her MPH program, Gina’s summer project in 1992 was to conduct a needs assessment for a “free pharmacy” for older adults with support of the Durham County Hospital Corporation and the Council for Senior Citizens. She interviewed social service providers, healthcare providers, caregivers and seniors. Two issues emerged from her research:

  • Many people were struggling to pay for their medicines and needed help.
  • And, equally concerning, some of the medicines seniors were taking were contributing to their health problems.

Gina used information from the project as the basis for her master’s paper and an abbreviated version was published in the North Carolina Medical Journal. A month later—with the aid of the Duke Endowment and support from other foundations—Senior PharmAssist opened its doors to the Durham community on June 23, 1994.

In 2001, Gina was named a Robert Wood Johnson Community Health Leader and the following year received the Bowl of Hygeia Award for Community Service. In 2005, she earned the Eunice Tyler Award for Excellence in Public Health Education from the UNC-CH School of Public Health, Department of Health Behavior and Health Education, and in 2006 won the Don Blanton Award for Outstanding Contributions to Pharmacy from the N.C. Association of Pharmacists and the Elna B. Spaulding Founder’s Award for making a significant difference in the Durham community. In 2008, Gina received the Power of Prevention Award from the N.C. Health and Wellness Trust Fund Commission for her advocacy and public policy efforts, and in 2009 earned the Jim Long Outstanding SHIIP Service Award from the Seniors’ Health Insurance Information Program and the AARP North Carolina Advocacy Award.

Ida Daniels, Administrative Assistant

Next to our executive director, Ida is our longest-serving staff member. She joined us as a part-time receptionist in 1999, through the auspices of the Senior Aides Program. When that program could no longer fund Ida’s position with Senior PharmAssist, we officially hired her to serve as part-time administrative assistant. Ida is a lifetime Durham resident, and her connections to the community, warm familiarity with our participants and professional skills help keep the office running smoothly.
