ABOUT WARWICK EMS
Serving Northern Lancaster County Since 1956
For 70 years, Warwick Community Ambulance Association has been committed to providing high-quality, compassionate emergency medical care to the communities we call home.
Today, Warwick EMS is a modern, nonprofit emergency medical services organization providing much more than emergency response. Through education, community outreach, special event coverage, emergency preparedness, and strong local partnerships, our commitment extends far beyond the ambulance.
2026
Warwick EMS launched Pennsylvania’s first prehospital sepsis antibiotic pilot program, bringing critical, time-sensitive treatment directly to qualifying patients before they reach the hospital.
leading the way
Warwick EMS launched its EMS education program, expanding our mission beyond emergency response to training the next generation of providers. Our first classes marked the beginning of a growing commitment to EMS education and workforce development.
investing in the future
Warwick opened a second station in Elizabeth Township, marking another chapter in our commitment to the communities we proudly serve across Northern Lancaster County.
expanding our reach
Warwick EMS has grown into a modern emergency medical services organization built on advanced clinical care, professional training, education, and community service — while remaining rooted in the same commitment to our neighbors that began in 1956.
built for today
What began with volunteer drivers and basic first aid evolved alongside emergency medicine itself. Today, Warwick EMS is supported by trained professionals, advanced technology, and an ever-growing scope of care.
EMS EVOLVES
Warwick’s first ambulance was loaned to the organization and housed in a local garage. Before the end of that first year, AMBUCS secured a 1954 Cadillac ambulance for the growing service.
The first ambulance
Dr. Arthur Griswold recognized the need for a local ambulance service in Lititz. With the support of Lititz AMBUCS, Warwick’s story began as a community effort built around helping neighbors in need.

She helped establish the organization’s Community Outreach program, which has since grown to include CPR education, car seat safety, Stop the Bleed training, and other prevention initiatives. Since stepping into the role, Colleen has helped certify nearly 400 people in CPR. For her, serving the Warwick community means making sure people know Warwick EMS is here not only when an emergency happens, but also through education and prevention that can help keep one from happening.
