Staff

Donna Rex
Executive Director
As a wash-a-shore to Cape Cod I quickly became accustomed to living my best beach life.
A graduate of Barnstable High School and Cape Cod Community College led me to a career in the Fire Service.
After completing 32 years as a fulltime Firefighter/Paramedic with the Barnstable Fire Department, my 2018 retirement was a brief 12 hours, as I returned to work the next day as Executive Director of Cape & Islands EMS, the position I currently hold.
Happily married, proud mama to 2 humans and 1 fur baby and a new favorite title as Grandma. My spare time is spent on the beach in our RV, practicing yoga or reading to my granddaughter and grandpups.

Jonathan Cook
Director of Operations
Jonathan is Cape Cod native who attended the Cape & Islands EMS EMT and Paramedic programs in the early 1990s. He retired as a State Trooper with the Maryland State Police where he spent his career as a Flight Paramedic and Tactical Paramedic in the Special Operations Division.
After retiring, he founded a company that created video training content for Emergency Services Programs in the Maryland, Virginia, and Washington DC areas.
Jonathan joined Cape and Islands EMS as a contractor in 2021 to help create educational content and was later brought on as staff where he designed, implemented, and is now the system administrator for the Cape Cod EMS Learning Management System.
He enjoys his free time with his family and also a pilot, he enjoys flying as well as dual-sport motorcycle riding.

Johnathan Olson
Education Coordinator
