Cancer Center

Local residents living with cancer benefit from convenient access to a range of cancer care services, thanks to the Johnson Memorial Cancer Center.

From radiation therapy to medical oncology, and American Cancer Society resources to support services, the Center offers virtually every component of cancer care. Saint Francis Care provides medical directorship of the Johnson Memorial Cancer Center.


Located within the JMMC is the 14-chair Karen Davis Krzynowek Infusion Center (KDKIC), which provides chemotherapy and biotherapy administration, transfusions, injections and other outpatient services in a comfortable environment. KDKIC also houses a pharmacy and laboratory onsite.

A full-time oncology/hematology practice is located within the JMMC, and it is staffed by Jay Thumar, M.D., a member of Saint Francis Medical Group.

The Center features a radiation therapy provided by Community CancerCare, a unique partnership of four area hospitals. Clinical oversight for radiation therapy is provided by Hartford Hospital's highly-acclaimed Helen & Harry Gray Cancer Center.

In addition to radiation therapy and medical oncology services, patients also have access to a wide variety of programs offered by JMMC, including social work services, nutrition consultation, educational programs, pastoral care consultation, support groups, and visiting nurse services. The Cancer Program's Enfield location is also home to a satellite office of the American Cancer Society.

In early 2016, the Johnson Memorial Cancer Center was one of 27 accredited cancer programs to receive the Outstanding Achievement Award from American College of Surgeons Commission on Cancer. Award criteria was based on accreditation surveys conducted during the second half of 2015. The 27 award-winning, cancer care programs represent approximately eleven percent of programs surveyed July 1–December 31 by the CoC in 2015.
