Anita Ruff, Executive Director

“Growing up, my family often didn’t have health or dental insurance. That was true for a lot of people in my community, and I saw friends and family struggle with decisions about work, health and money constantly. At Oasis, we take away some of that stress so our patients can focus on their health.”

Bronwyn Sewell, NP, Per Diem Nurse Practitioner

I believe that healthcare is a human right, and I am honored to work at Oasis for this reason.  Supporting patients in the dignity of being able to care for their health and wellness is a meaningful part of my practice as a nurse practitioner.


Dr. Robert Swan, DMD, Volunteer Dental Director & Retired Dentist

Following over 40 years in private dental practice and 5 years as a volunteer provider and director at a free health clinic, Oasis was a natural home for me when my clinic closed during COVID-19. First, as a volunteer provider and now as the volunteer Dental Director, my experience at Oasis Free Clinic has been personally and professionally rewarding. 

Dental health is integral to a person’s well-being and should be available to all and not limited by financial ability. As the name implies, Oasis provides excellent and compassionate care to all of our neighbors in need. 


Tiffany Tyler-Bisson, RDH, Dental Hygienist

David Inger, MD, Family Physician & Volunteer Medical Director

“When you are a physician, there is something different when you volunteer. It’s more gratifying.  It feels more like a privilege. Not having health insurance puts you at another level of vulnerability, and it’s humbling that people trust us with their stories and their lives.”

Kristen Kellner, Retired Human Resources Professional - Board Vice President

“In 2010, Oasis gave me a purpose by allowing me to volunteer my services as an HR staff development specialist. I was on a leave from my job due to my primary focus of undergoing cancer treatment. The longer I volunteered, the more I appreciated my healthcare coverage and my employer’s benefits package. This perspective allowed me to realize the vital role Oasis Free Clinics fills for those in need of our services. I’m proud to serve on our board.”

John LaCasse, ScD, Retired Healthcare Leader

“Oasis serves some of Maine’s most vulnerable citizens. I’m thankful to have the opportunity to support that vital mission.”

“I have a great appreciation for how complicated and complex our healthcare systems are.  I feel strongly that everyone should have access to healthcare and trying to navigate our systems can be overwhelming especially for the most vulnerable.  Oasis provides needed healthcare services to our community in a respectful, supportive way that allows patients to manage and improve their health which benefits not only the patient and their family but our community as a whole.  I believe in the mission of Oasis and would be honored to have the opportunity to work with the team to continue to provide the much needed services and grow the organization.”

Seth Ramus, PhD, Retired - Board President
