Meet the Team

David Addiss, MD, MPH


David is a public health doctor whose meandering career has involved migrant health, mountain medicine, neglected tropical diseases, research, philanthropy, and global health. An opportunity to study public health at Johns Hopkins University rescued him from a decadent life as a climbing bum in Yosemite. 

“I am absolutely delighted to be working with such amazing people, breaking new ground, and navigating the rich, creative waters of compassion, ethics, and global health.”  

Ashley Graham, MJ, PhD

Director of Research and Operations

Ashley is a medical anthropologist interested in ethics, global health policy, and infectious disease. She loves living in Atlanta, trying different foods around the world, writing, and doing anything outside. Her latest adventure is as ‘Mama.’

“I met David at a conference on ethics in global health and three weeks later I started working with FACE. The program really is that special.”

Heather Buesseler


Heather is a global health and humanitarian professional committed to health equity and social justice for marginalized populations. A native Minnesotan, she is based Minneapolis and loves urban and wilderness adventuring with her 4-year-old daughter. She also holds an adjunct faculty position in St. Catherine’s University Global MPH program in St. Paul.

“The work of designing compassionate, values-based health care is truly where I want to dedicate the remainder of my career.”

Patricia Richmond, MPH

Project Support Specialist

Patricia’s professional journey has always been fueled by compassion. Her studies of world religions, peacemaking, and social permaculture underpin a varied career encompassing public health, public schools, and the promotion of robust, resilient communities. Patricia parents, sings, and tends an ever-evolving food forest just outside the city limits of Atlanta.

“Working with FACE is an affirming intersection of the many paths of inquiry I have followed, in the hopeful quest for a more compassionate world.”

Amy Richards, MPH Candidate


Amy is a socially and globally focused public health student, seeking to secure a voice and dignified standard of living for the least heard and visible communities via partnership they own. Forever curious and driven by care, you may find her asking questions like “who have we forgotten?”, “what assumptions are we making?”, and “have we adequately incorporated human context into this initiative?” 

“It is crucial we truly see the humans and communities we walk alongside as we support their potential, quality of life, and inherent value.”

Chimdi Ezeigwe, MPH Candidate


Chimdi is a first year MPH student studying Health Policy and Management at Rollins. She is particularly interested in global health and hopes to use her  experiences in policy and management to work towards improving health outcomes in the developing world by creating sustainable and quality systems. In her free time, Chimdi enjoys trying new recipes, listening to music, and exploring different parts of the city.

“I am very excited to be working at FACE and to further explore the importance and impact of compassion in public health and healthcare!”

Nick Chang, MPH Candidate


In pursuing a master of public health, Nick intends to specialize in mental health policy to address systemic inequalities and unintended outcomes of current mental health care structures. He is particularly interested in examining the effects of societal stigmas on access to and usage of mental health services. During his time at Rollins, Nicholas hopes to further his understanding of health policy and mental health through coursework and build relationships both on and off campus with organizations and individuals that will become catalysts for change in the mental health policy space.

“Working at FACE creates opportunities to jump-start the conversation about mental health and well-being around the world.”
