I live in Boston and have worked in the field of education for the last 13 years. I am currently working as a Senior Program Manager at Harvard Catalyst | The Harvard Clinical and Translational Science Center. Previously, I worked at the Perkins School for the Blind & Lindamood Bell Learning Institute. Originally from Georgia, I moved to Boston, to attend Boston College, graduated, and stayed. I love fighting for justice at home and abroad, traveling, reading, home projects, cooking, and meeting new people.

Karen Walker

I am a retired educator with 39 years of experience in public and private education.  I worked as a counselor at the University of Missouri, St. Louis; as a Project Coordinator at Northeastern University; and after years as a public school counselor, began my 16-year career as a school principal. In addition, I taught graduate level courses at Northeastern and Lesley Universities.

Since retiring, I have become active politically and volunteer with Project Have Hope, a non-profit that seeks to empower women in the Acholi Quarter of Uganda.

Having worked with both typically developing students and those with disabilities, I believe that students generally learn best in an environment that supports diversity, individual effort, responsible citizenship and acceptance of differences.  In a school where all students are valued and respected and where the curriculum is differentiated to reach diverse learners, children learn to value themselves and to respect others.

My husband Richard and I have a stellar daughter, Anna, who served as a Peace Corps Volunteer in Mozambique; a wonderful son-in-law from Mozambique, Rodolfo; and an amazing grandson, Gabe!


Rick McCartney, NP

I'm a Nurse Practitioner with a focus on community and public health. I currently run iRewardHealth, a software company helping people to build healthy habits. Big problems excite me, and I look for ways to find effective interventions that can scale to improve quality of life for people around the world. The WaWa Project is important to me because I believe that education is a great democratizer, and I'm excited to see what we can learn as we support people in pursuit of comprehensive education.
