I am the 39th President of the Board of Trustees for The Treatment and Learning Centers (TLC), and I am excited to continue our efforts to position TLC as the community leader in improving the lives and expanding possibilities of individuals with special needs in Maryland, DC, and Virginia. As I enter my second term as a Board Member, I am inspired by the passion, commitment, and hard work that our leaders and community members exhibit every day in helping individuals with special needs to meet their highest potential. It is remarkable to think about how far we have come; we started in a local church basement, and we now we serve over 2,000 individuals with special needs each year and have three dedicated locations!
My predecessor, Melissa Pappas, who has been a Board member since 2009 and served as President from 2018 to 2021, has done a tremendous job in solidifying TLC’s position as an expert, reliable source of support and help for the community, allowing us to share our expertise and provide bright futures for as many individuals as possible. I look forward to continuing to position TLC to flexibly navigate through the ever-changing needs of our community so we can successfully help as many families as possible.
Since 1950, TLC has strived for, achieved, and continues to position itself as a highly visible, leading-edge organization with strong collaborative and advocacy relationships, and plentiful resources that support quality programs, staff, and facilities for individuals with special needs. This success is accomplished through an active and committed community of current and past Board members, volunteers, donors, faculty, staff, and more. TLC is truly a village of individuals from different backgrounds working collaboratively to make a difference in the lives of others. It is an impassioned community of caring.
I would like to thank this special community for their commitment and support. TLC is in the business of providing the best therapy, education, employment services, support and care possible to provide a foundation for the achievement of greater personal independence and success for our clients. TLC could not help others without your help.
