Marva E. Overton – Executive Director
I come to this work with the knowledge of, and belief in, the strength and resilience of African Americans. I recognize that the problems we face are deeply rooted in our history as a people in this country.  Yet, I know of our achievements and successes despite the odds. I do this work out of the obligation I feel to honor my ancestors and use the blessings I have received to contribute to the positive advancement of the black community and all of humanity.
Mila Jackson, Client Services Coordinator
I was called to do this work six years ago because I lost a colleague and dear friend too soon, due to breast cancer. My friend had insurance but was unable to afford the copayments for doctor visits and lifesaving tests. That is why I am passionate about the work AAAHCT does to help uninsured and underinsured clients receive the services they need for early detection and early intervention.

My work with AAACT, specifically the Inter-generational Gardening Project, is a labor of love and restoration. My personal experience with gardening began with my maternal grandmother who kept a garden out of necessity, and my mother who was passionate about growing edible as well as decorative plants. Gardening is an integral part of the African American heritage, so the Inter-generational component of the Gardening Project is so important for our community. I’m committed to the Project because of the long-term impacts that can be realized for all participants.

Shameika Bunton, Adult Team Lead
I was introduced to gardening through my grandfather Chester Bunton, as well as my “Big Mama” (great grandmother) Nail Clark. I’m a single mother of a 13-year old son, Carl. I’m very grateful that Carl and I have been able to experience gardening together on this level. I do this work because it connects me to my past and gives me the opportunity to work with others to garden, which is something I truly love.

I’m known to most as LadyJoy, the on-air radio personality at KAZI 88.7 FM, The Voice and Soul of Austin. As a published book author and motivational speaker, I have a heart to serve others by modeling the potential to live with more joy regardless of the circumstances of life. My work as a team lead with the Inter-generational Gardening program allows me to share my passion for building up people through collaboration, relationships and group learning.
Angela Bigham, Team Manager

For many years I have been interested in addressing the health status of the Black community. I currently serve as the health ministry leader at my church. I extended my efforts by working with AAAHCT because I am passionate about educating and helping people to become healthier physically, spiritually and mentally.

Sharon Ellerby, Team Manager
I’m very passionate about health and wellness and desire to assist my community through A Better Me in accessing tools and resources available to enhance their knowledge and skill to positively reach their health goals. I enjoy using my creativity, passion and commitment to A Better Me to encourage those around me to make healthier choices to become a better version of themselves.
Lee McCormick, Team Manager
I’m always looking for ways to help others. Helping others should be done as much as possible. It doesn’t just have a positive impact on the person being helped, it’s good for everyone. We should want to help others succeed in life, because that in turn, helps us. Being part of A Bette Me, allows me to do just that. If you want to live longer, be a giver.

Joan Roberts Scott
Joan Roberts Scott, Team Manager
I am a retired employee from the State of Texas Disability Determination Services.  I got involved in work with AAAHCT because I have experienced being overweight and not being physically active. I also have a family history of chronic diseases. For 35 years I have been involved in improving my health and helping others do the same.  As a Team Manager, I am able to encourage and help African Americans focus on their overall health and learn to enjoy doing it.
Selma Washington, Team Manger
I joined the AAAHCT A Better Me program in February 2018 as a Coach. Since December 2019, I am also serving as a team manager. I enjoy working alongside my players by setting up weekly step challenges that allow us to help each other get fit and move more. I decided to join this effort to help keep other African American women accountable and to help promote healthy lifestyles with eating and exercise.
