Oby Ukadike, MBA

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, for college and stayed, braving each winter like a seasoned pro.


Bridget Koha  

Executive Director

Bridget founded the WaWa Project out of a desire to live out Proverbs 31: 8-9 “Speak up for those who cannot speak for themselves, for the rights of all who are destitute. Speak up and judge fairly; defend the rights of the poor and needy.”Her heart for Ghana began in 2006, when she visited the beautiful and hospitable country. She worked as a chiropractic assistant (C.A.) at a busy practice in Newton, MA from 2009 until 2012. She managed the Boston Benevolent Chiropractic Clinic, a clinic bringing free chiropractic care to those in need at three sites in Boston. Prior to working as a C.A., she traveled abroad with her husband in Germany and Ghana. She holds a B.A. in International Relations from Boston University. At the moment, Bridget and her husband can be found chasing their one-year-old daughter, Emily – a daily blessing in their lives.

Karen Walker

Karen Walker is a retired educator with 39 years of experience in public and private education.  She worked as a counselor at the University of Missouri, St. Louis and as a Project Coordinator at Northeastern University.  After her years as a public school counselor, Karen began her 16-year career as a school principal. In addition, Karen has taught graduate level courses at Northeastern and Lesley Universities.

Since retiring, Karen has become active in state and national politics and volunteers 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, Karen believes that students generally learn best in an environment that supports diversity.  She believes that effective education occurs in a climate of support for 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.

Karen and her husband Richard 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.
