 Maureen has a Bachelor of Arts degree in Special Education and a Master of Science in Restorative Practices. Maureen spent 38 years as an educator before retiring in 2019. During that time, she taught students of various grade levels with intellectual disabilities, learning disabilities, autism spectrum disorder, and/or emotional/behavioral disorders. She worked as a teacher, case manager, and department chairman, as well as a class adviser, assistant coach, mentor, small-group leader, Restorative Practices Trainer, Faculty Welfare chairman, and Sunday School teacher. Although Maureen has taught a variety of subjects, her primary passion and talent is reading, with a particular emphasis on the Read 180 and System 44 programs. Her love of teaching, devotion, and commitment to excellence in the classroom were recognized by her colleagues, parents, and students when she received the 2012 B.E.S.T. Teacher award.


Maureen credits her success in life to God, family, and the hard work of using God's gifts to accomplish His will, with a focus on building and cultivating meaningful connections with others. She has learned through experience that working "with" people rather than "to" or "for" them is the most effective way to effect positive and long-term change. As a result, she fully expects, supports, and promotes open collaboration, shared decision making, complete transparency, and accountability among everyone who are committed to working together to achieve BRAVO's objectives and goals.

Maureen lives on Lake Marion in Manning, SC, with her husband, Jose. She enjoys reading, working out, gardening, and landscaping. She and her husband enjoy spending time with family and friends, boating, fishing, volunteering, and visiting other South Carolina destinations. Maureen and Jose have a profound love for God, family, their community, and our beautiful country.

Upon returning to the US, she completed a Masters in Religious Education Degree (with Social Work emphasis) from the Southern Baptist Theological Seminary. She was employed as a social worker at the Sumter County Department of Social Services for several years, teaching and guiding women who were seeking assistance with employment. Because she has always had a passion and heart for teaching, she changed careers and served for several years as a preschool teacher in a private setting. In 1995, she began her employment at the Sumter School District, serving as a paraprofessional with the Hearing Impaired program. Her final six years were with First through Third Graders in the LD (Learning Disabilities) class at Millwood Elementary School in Sumter until her retirement in 2015.


Brenda’s experience in education has given her a unique awareness of the heart, needs and challenges of local school teachers (both public and private) and their desire to give of their best to their students. This is what attracted her to BRAVO and its mission in Clarendon County. She was honored to be asked to serve as Vice President of this organization.


Brenda has been married 49 years to her husband, Marion, who has served as a minister and church-planter at various churches in NC and SC. She has had many roles in the churches they have served, especially in the education areas. She now
leads Discipleship Groups in her local church. They moved from Sumter to Lake Marion in 2020. She
enjoys reading, scrapbooking, travel and spending time with family and friends on the lake.

Vicki graduated from Sumter High School, Sumter South Carolina, where she learned all clerical skills needed for her dream to work as a secretary in a law firm. Her skills led her through law offices, Belk Department Store Customer Service Office, Sumter Orthopedic Office, and finally back to uptown Sumter to the Master Equity Office. From there, she spent 19 years in the Third Circuit Solicitor's Office in Pretrial Intervention and ended as a Victim Advocate. Being able to help people through their legal problems is what she most enjoyed. Vicki was selected as a TWIN Honeree, served on the PTI Association Board for South Carolina as the Treasuer, and has served her life in her church in various areas. 

Being sensitive to the needs of people is what drew Vicki to BRAVO. She has relatives and friends who teach both in the public and private schools and has always had a heart to listen to them about their love for teaching and the challenges that go with caring for the children of our future. Empowered with skills she learned working with people all these years, Vicki believes she can make a difference in Clarendon County through her work with BRAVO.
