Kristi Caldararo

Board Member

“I was immediately drawn to Hosts for Hospital’s mission as it speaks to the selflessness of so many individuals within our community willing to open their homes and/or secure lodging partnerships for those in need. Hosts for Hospitals takes away the financial housing burden and allows families to focus on what is most important, the health, safety and well-being of their family members seeking care. My passion for people is the reason I sought out a career in healthcare and I know that passion resides equally within the Hosts for Hospitals team. As a member of the Hosts for Hospitals Board, my goal is to give back to our community and support an organization that is founded in empathy and experience.”

John Morris

Board Member

“During my childhood, my mother was ill for extended periods of time. Each time she needed specialty care she would be transferred to a facility that was prohibitively distant. For nearly a year during one episode we were only able to see mom on weekends.

Today, I believe that for a life to be truly full, four dimensions must be nourished: career, health, family and contribution. After moving back to Philadelphia, I was looking for an opportunity to leverage my healthcare career experience to give back to my community. When I learned of Hosts for Hospitals, I thought what a perfect opportunity. I can only imagine what it would have meant for my own family!”

John is a dynamic healthcare leader with diverse experience across the healthcare ecosystem including provider delivery systems, payers and private equity.
John spent his early career leading go-to-market strategy and execution for several organizations targeting healthcare payers across all 50 states.
