Sarah Hallmark is the Assistant Director of Project Horseshoe Farm.  Sarah has been a key contributor to the development of Project Horseshoe Farm from its earliest stages, including serving as a Horseshoe Farm Board member for 11 years.

Sarah began her career as a psychiatric social worker at Northport Medical Center and then with the Geriatric Department of the University of Alabama Birmingham (UAB) Center for Psychiatric Medicine.  After returning home to the Black Belt, she helped develop a new geriatric psychiatry program at Bryan Whitfield Memorial Hospital in Demopolis, Alabama.  She spent 13 years as the lead social worker in the program prior to joining Horseshoe Farm as the Greensboro Site Director and Assistant Director.

Sarah was born and raised in Demopolis, Alabama.  She received her B.A. in Business Administration from Mary Baldwin College and her Master of Social Work from the University of Alabama.  She is actively involved with the community including in her roles as the Chairman of the Demopolis Historic Preservation Commission, Board Member of the Alabama Black Belt Foundation, President of Demopolis City Schools Foundation board, and member of the Marengo County Historical Society and the Two Rivers Arts Council.  She also serves on the Quality Assurance Committee of the Marengo County Department of Human Resources and is a member of Class XXIII of Leadership Alabama.

Born and raised in Demopolis, Alabama, Lashanda has known since childhood that her purpose was to help others.   LaShanda’s family and faith instilled in her that helping our neighbors and those in need is the responsibility of those who have the ability to help. She became a youth Sunday School teacher at the age of 10 due to her love for children and her desire to share knowledge with others.  As an adult, much of her professional and personal life reflect her values of supporting and advocating for the vulnerable, those facing challenges, and those in need.

Lashanda started her career with Marengo County Emergency Management Services (EMS) as a Senior Dispatcher.  After 11 years of EMS service, her deep desire for greater involvement with the community prompted her to transition to become a Social Service Caseworker with the Marengo County Department of Human Resources.  After two years working in the Children and Family Services Unit, she was promoted to Service Supervisor.  As Supervisor, she wore multiple hats including supervising and leading a team of caseworkers, investigating adult abuse and neglect, and overseeing the recruitment, training, and licensure of foster parents.  She also helped collaborate across agencies, worked with child advocacy centers, and recruited, trained and licensed foster parents.  

After learning about Horseshoe Farm, LaShanda instantly felt a deep sense of connection with Horseshoe Farm’s mission and values and was drawn to the sense of community and belonging the organization tries to foster. In joining Horseshoe Farm, LaShanda hopes to deepen and build upon her past community service work and to make a positive impact on the lives of children, adults, the Fellows, and the broader Hale County community.

Outside of work, LaShanda has been active in devoting her time to volunteer in community-based initiatives.  For multiple years she has headed the Local Christmas Program for Marengo County Department of Human Resources which provided assistance with Christmas gifts for children of Marengo County.  She has also spent the previous five years helping lead and organize an annual picknick that successfully brought together foster parents for fellowship and support.

In her personal life LaShanda enjoys spending time and making memories with her 2 children, Zamaria and Carter, and her husband Bryan. LaShanda holds a bachelors of science degree in Criminal Justice from Columbia Southern University.

Nicole Zermeno

Pomona, CA Site Director


Nicole Zermeno is a Southern California native, she was born in Orange County and moved to Riverside at a young age. As a child, she was actively immersed in and engaged with the local community center where she spent most of her days. By participating in different events, she developed strong relationships with the staff members who have been key role models in her life. This orientation towards service and community building led Nicole to continue finding ways to make a difference in the spaces around her, including volunteering at a senior center, lending a helping hand at different soup kitchens in Riverside, and serving as a member of a grantmakers committee. 

Nicole comes to Project Horseshoe Farm with a wealth of experience, having worked with elementary, middle, and high schools throughout the Corona-Norco Unified School District as a peer educator and behavioral therapist over the past five years. She also continued to work in behavioral therapy with a private agency during this time and holds a degree in Early Childhood Studies from California State Polytechnic University, Pomona. Her interest in Project Horseshoe Farm stemmed from its comprehensive community health mission and various levels of support offered. The organization’s purpose felt very personal as it drew on many of her own experiences and strengths as a therapist in helping people move forward when they may be struggling. “It has always been my calling to be in this kind of position because working closely with people is what I would like to do forever,” she says. “If a younger me were to imagine where I would be now, I would have said a place like Project Horseshoe Farm.”

When thinking about her goals as Site Director, Nicole says she hopes to become a stronger leader in the community and is excited by the opportunity to learn alongside all the Fellows. She is interested in gaining more experience in non-profit capacity building, with the intention of pursuing a master’s degree and maybe even starting her own community-based non-profit one day. “Even though the Pomona site was started in 2020, it has already made an impact on so many people. Despite the challenges of launching during COVID-19, we are thankful that the site has thrived and we have built so many relationships throughout the community. Everyone in Pomona is so friendly and so united in their commitment to helping others out and contributing to the strength of the community. It has been wonderful and motivating to see and be a part of.”
