Christopher Wright received his Bachelor of Science degree in Biochemistry with a minor in Mathematics from the University of Rochester in 2013 and earned his medical degree from Sidney Kimmel Medical College at Thomas Jefferson University in 2017 with an emphasis in clinical and translational research.

Dr. Wright went on to complete his internal medicine internship and residency in Radiation Oncology at the University of Pennsylvania in 2022. During residency, Dr. Wright was invited to present his research at several national conferences and was published in peer-reviewed medical journals for topics including lymphoma, cancers of the lung, breast and oropharynx, and dietary interventions for cancer patients. Dr. Wright spearheaded an international, multi-institutional consortium dedicated to the study of integrating radiotherapy with novel cellular immunotherapies.

During his residency, he was extensively trained in the use of advanced radiation techniques, such as image-guided radiation therapy (IGRT), intensity-modulated radiation therapy (IMRT), stereotactic body radiotherapy (SBRT), stereotactic radiosurgery (SRS), and proton therapy.

Dr. Wright joined Radiation Oncology Associates in August 2022. He enjoys his time outside of the clinic skiing, golfing and exploring New England with his daughter and golden retriever. “I am deeply humbled by the opportunity to provide compassionate cancer treatment of the highest quality to my community and to carefully navigate our patients through their complex diagnoses and longitudinal cancer care.”

Andrea McKee received her Bachelor of Arts degree in biology in 1992 from the University of Pennsylvania with honors. She graduated from Columbia University College of Physicians and Surgeons in 1996. During college and medical school, she participated in laboratory and clinical research prior to continuing with her clinical training.

Dr. McKee stayed in New York City for her internship in internal medicine at Lenox Hill Hospital. She continued her training in radiation oncology at Memorial Sloan-Kettering Cancer Center, where she was named Chief Resident for 2000-2001.

During residency, Dr. McKee researched clinical outcomes in patients with tumors of the prostate, uterus, cervix, and musculoskeletal system. She developed expertise in intensity modulated radiation therapy (IMRT), high dose rate (HDR) brachytherapy and stereotactic radiosurgery. After finishing her training at Memorial Sloan-Kettering Cancer Center, Dr. McKee joined Radiation Oncology Associates in 2001.

Dr. McKee helped establish an HDR brachytherapy program in southern New Hampshire in 2004. With a team of neurosurgeons, oncologists, physicists, radiation therapists and oncology nurses, she developed a stereotactic radiotherapy program at the Elliot Hospital where she served as the medical director and co-director of the Elliot Radiosurgery Center. She now serves as the Chair of the Department of Radiation Oncology at Lahey Clinic in Burlington and Peabody.

“I became a radiation oncologist in order to practice medicine in an area that challenged me both emotionally and intellectually. The technological and therapeutic advances in radiation and medical oncology seen over the past few years have led to impressive and meaningful improvements in overall survival and quality of life for our patients. It is an exciting time for those of us who share in the privilege of caring for patients with cancer.
