Robinah Nansamba, NP

Master of Science: Regis College

Nurse Practitioner

A graduate of Regis College, Robinah started her career as a registered nurse before deciding to become a family nurse practitioner. Asked why she became a nurse practitioner, Robinah explained, “I am a problem solver and being a nurse practitioner gives me greater ability to work closely with my patients to determine the cause of their illness and how best to treat it.”

Robinah enjoys the fast pace of practicing at ReadyMED and dealing with all different types of medical issues. “I have worked in acute care since 2014 and after a rotation in the emergency room while doing my clinicals in school I decided the pace of emergency medicine suited me so I decided to specialize in urgent care,” she explains. Robinah’s approach is to treat each patient with respect and always acknowledge their feelings about the issue at hand. “I believe in working closely with my patients to develop a specific plan of care that is tailored to their needs and able to be easily followed after their discharge.”

In her spare time Robinah enjoys running to stay in shape and Zumba.

Residency: Brown University
 UMass Medical School
Bachelor of Arts: Yale University


Dr. Elyssa Pellish worked as an emergency room physician for many years and now uses her experience to help patients at ReadyMED Plus in Worcester.

“I like the fact that ReadyMED Plus can handle such a wide range of care issues and allows me the opportunity to help people feel immediately better,” she explains. “Plus working here I have immediate access to blood work and CT scans. I can also refer patients to other Reliant specialists if they need them.”

Dr. Pellish always makes a point to get to know her patients and look at all of their care issues. “I try to care for the whole patient even though they may have visited for one specific complaint. I will look at diet, nutrition and physical activity, for instance, since so many things can figure into a diagnosis.” Dr. Pellish is very comfortable doing minor procedures in the office to help patients including closing lacerations, incision and drainage, fracture care and splint placement.

Working at ReadyMED, Dr. Pellish says that she truly enjoys making connections with her patients. “When you really connect with someone and are able to help them it’s very satisfying…it makes all the hard work worthwhile.”

When she is not busy helping patients, Dr. Pellish enjoys hiking, running, reading and being outdoors as much as possible. She also enjoys spending time with friends and family.

Dr. Masooma Rehmtulla

Saint Vincent Hospital

Bachelor of Surgery: 
Maharashtra Institute of Medical Education and Research


As the child of a dermatologist and a pediatrician, Dr. Masooma Rehmtulla couldn’t help but learn about the medical field when growing up. “As a young girl I grew up listening to conversations at the dinner table about medicine. My parents discussed how they helped their patients each day and that was very inspiring to me,” she explains. “That helped me make the decision to pursue medicine and become a physician.”

After graduating from her Internal Medicine residency, Dr. Rehmtulla practiced as a primary care physician for four years. “As a primary care physician, I had an opportunity to manage chronic as well as acute medical issues. Taking care of the urgent care needs of my patients was highly gratifying for me, and hence I decided to shift my focus and leverage my expertise towards an urgent care position in an out-patient setting.”

Dr. Rehmtulla began treating patients at ReadyMED, Reliant’s urgent care clinic, in 2019. “I think you can have one encounter with a patient and have a good relationship. You may or may not see them again, but that good rapport you established at the first visit is still really important.”

When she is not busy helping patients Dr. Rehmtulla enjoys getting out and traveling the world. “I absolutely have wanderlust,” she explains. In the past year, my husband and I have traveled to many beautiful places. “I love to explore different cultures and cuisines.”
