Dr. Margaret McCahan

Doctorate: UMass Medical School
Internship & Residency: UMass Memorial Medical Center


Dr. Margaret McCahan has worked in both pediatrics and urgent care during her career. Now she enjoys caring for patients at ReadyMED PLUS, one of Reliant’s urgent care offices. “I’ve always enjoyed working in urgent care,” she explains. “You never know what you’ll be treating so you always have to be on your toes. Plus I love the fact that it allows me to use my pediatrics background when I practice.”

Dr. McCahan likes the fact that Reliant’s urgent care facilities can treat so many different conditions and help people avoid going to the emergency room when it’s not necessary. “Both parents often work these days and having urgent care available at a moment’s notice when a child is sick can really make a difference,” she explains. “Parents can also avoid the long wait times that occur when they go to the emergency room. I also like the fact that seeing patients at ReadyMED I have an opportunity to encourage people to visit their primary care doctor to better manage their problems and take their medications.”

In her work Dr. McCahan says that she strives to build a relationship with all the patients that she treats. “Although I may not see the patient that often, I still think you can bond with them and start building a relationship. And if I am treating a child, I strive to establish a good relationship with the parents too, as that’s very important.”

According to Dr. McCahan, electronic medical records have made care a lot easier. “You not only have your patient’s health history and other key information at your fingertips but you can also send a note to their primary care provider telling them how you treated their problem…it’s really a great asset.”

When she is not busy seeing patients, Dr. McCahan enjoys family time with her husband and three sons. She also likes yoga, going to concerts and the theatre, and being outdoors with her Labradoodle. Dr. McCahan also enjoys traveling when she can find the time, and recently visited Ireland with her family.

Fellowship: UMass Memorial Medical Center


For Dr. Peter Murphy, it was some classes back in high school that opened up his eyes to a career in medicine. “The first time I ever really enjoyed something academically was studying the biological sciences in high school,” he explains. “I had people in my family who were nurses, but no doctors. I could tell that working in a lab or at a desk wasn’t for me. So the field of medicine, with its ability to help others, seemed like a great choice.”

After graduating from medical school, Dr. Murphy started his career in pediatrics. When he was around 40 years old, he moved his family to Indonesia so he and his wife could work in a health clinic. “There was an enormous need for medical care there, including a high infant mortality rate and other problems. We thought we would stay forever, but it didn’t work out that way. However, it was an amazing experience that I will always remember.”

One of the things that Dr. Murphy truly enjoys about his job is interacting each day with patients. “I love being a pediatrician because of the families you meet. It’s very gratifying when they come in concerned about something and you can reassure them. People are obviously very worried when their children are sick, so we really strive to not only do a great job with the medical care, but also let them know their kids are in good hands. Everyone here is very good at caring for people and it really shows.”

In his spare time Dr. Murphy enjoys outdoor sports such as hiking and climbing, as well as going birding with his wife. “We like to kayak, bike ride, and go camping. We’ve camped from the White Mountains to Mt. Desert Island and have kayaked all over Massachusetts.” Dr. Murphy also enjoys teaching and is a pediatric advanced life support instructor as well as an Assistant Professor of Pediatrics at UMass.
