Development Director

She’s worked in the nonprofit and NGO space for over 12 years wearing multiple hats – always with a focus on social justice – in the education and STEM sectors, but a recent role made her realize that she enjoys the fundraising side the most, especially connecting with people on their passions and interests. In her spare time, she loves to spend time with her two young kids, Finley and Sloane, and her husband David. They like to hike and explore all the diverse neighborhoods that Dallas has to offer. She’s also certified as a life coach and enjoys coaching women on burnout, career change, and living a life of purpose and meaning.
