About Us


Our Mission is to offer hope and support to these children and their families. We provide prevention services, educational programs and group activities that empower Kidney Kids to take charge of their health, embrace their future, and achieve lifelong success.

Our Vision is to see every child living with kidney disease thrive.  Our hope as we engage kidney kids is they learn to take charge of their health; manage their condition and embrace their future.  We strive to build a supportive community where families feel nurtured and encouraged.   Our goal is to provide a safe, caring environment where everyone in the kidney kid family can learn, grow and realize their potential. As an organization, NW Kidney Kids strives to be self-sustaining, known as a compassionate force well recognized and respected as one which operates with integrity. We have a positive influence in the kidney disease community both locally and nationally. To do this, we are always seeking to improve and expand our programs to make them relevant and valuable to the needs of more children/families.


Meet our Board of Directors

David Rozansky, MD, Ph.D, Board President Dr. David Rozansky, a respected pediatric nephrologist passionate about caring for his patients at Doernbecher, has been with the Board since its infancy in 2007. Not only does David give us depth and insight as a physician treating children with kidney disease, he owns one of the most impressive collections of kid-friendly neck-ties ever assembled. He lives with his wife Elana in Lake Oswego, proud of his two sons and an avid, intelligent sports fan.
Cory Roletto, Board Vice President Cory followed his wife's example and joined our Board in 2013. As a successful local media design business owner, he brings both technical knowledge and leadership expertise to keep our social media sharp and our practices sound. Perhaps his best contribution is as a donor dad to a kidney teen, Anthony, the eldest of his three busy boys.
Sharon Fleming, Board Secretary Sharon brings a welcomed enthusiasm and fresh perspective. A persuasive professional realtor by day; and an always tenacious parent advocate for her daughters; Sharon's energy and ideas are already making an impact on our Board culture. Mother to an accomplished young adult with kidney disease, her daughter Alex is a valuable volunteer as well.
Aaron Bayne, MD Dr. Bayne is a Pediatric Urology serving Kaiser and Doernbecher Children's Hospital.

He offered his talents and rich background steeped in knowledge of renal disease early this year. His networking, connections and fundraising savvy are already paying big dividends. We appreciate Lance's vision to bring hope and happiness to the kidney community through service and hard work. When he's not on the road, or running on one, he lives with his wife and five children in SW WA.

Founder and Past Board President (2006- June 2013). Dr. Randall Jenkins, or "Dr. J" as he's fondly known by his patients, is the longest practicing Portland area pediatric nephrologist. He blends his vast experience with a deep care and compassion for patients.

Suzanne Billings
Suzanne Billings, MSW, LCSW.
Suzanne Billings was a pediatric social worker who dedicated much of her professional life to working with families of children with kidney disease. Suzanne was integral in the development of NW Kidney Kids and served as President of the Board from 2013 until her death in 2017. Suzanne radiated joy and pride in her kidney kids' accomplishments; she was a true champion for her families and is beloved and missed by all whose lives she enriched over the years.

In the spirit of Suzanne's life work, a scholarship has been established to promote independence and self-empowerment. The purpose of this scholarship is to assist in the development of skills and knowledge to facilitate life-long self-sufficiency for a "kidney kid". These funds can be used to support the higher education or technical training of a young adult with kidney disease.

The Suzanne Billings Memorial Scholarship will be awarded annually by NW Kidney Kids in keeping with its mission to encourage young people with kidney disease to realize their potential and embrace their future.
