PSC Partners is fortunate to have a very talented and motivated group of people serving on its Staff & Registry Team.

Our Staff

Ricky Safer - Founder and CEO

Ricky is the CEO and Founder of PSC Partners serving in a volunteer capacity. After having led the life of a health nut for decades, Ricky Safer was shocked to receive her PSC diagnosis in 2003, and then to discover that there was little accurate information or support available for PSC patients. Still reeling from her recent diagnosis, Ricky decided she didn’t want to wait around to see if things would improve. In 2004, with the help of her family, her hepatologist (Dr. Everson) and two friends from the support group (Lee Bria and David Rhodes), Ricky founded PSC Partners Seeking A Cure. Ricky’s years of volunteering with CCFA locally and nationally and her position on the board of the Donor Awareness Council provided her with the background to get PSC Partners Seeking a Cure off the ground. Ricky has served on the Nutritional Panel for CCFA, and also received the CCFA Sigman award.

Ricky feels extremely lucky to have her family as her loyal support group and constant helpers. One of her greatest joys is spending time with her family—her husband (Don), daughter and son-in-law (Elissa and Steven), son and daughter-in-law (Adam and Sue), and grandkids (Sam, Lily, Rowan, and Hudson). She enjoys her role as CEO of PSC Partners, and continues to be passionate about finding a cure for PSC, and making life better for all PSCers. In Ricky’s other life, she taught foreign languages and provided cross-cultural training at the University of Denver. Ricky received her B.A. in French with honors from the University of Michigan, and her Master of Arts in Teaching from Johns Hopkins University. Ricky can be reached at  (Full-Time Volunteer)
