Our Doctors

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.

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 immediate care needs of my patients was highly gratifying for me, and hence I decided to shift my focus and leverage my expertise towards a care position in an out-patient setting.”

Dr. Rehmtulla began treating patients at ReadyMED 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.”

Nurse Practitioner Marilyn Robinson is a graduate of Regis College in Weston, Massachusetts with a Master of Science in Nursing. She first worked as a RN and then became an Advanced Practitioner because she wanted more interaction with her patients and to expand her care capabilities. Marilyn’s approach is to provide the patient with as much education as she can and then guide them to make positive choices about their overall health. Working at ReadyMED, Marilyn sees all types of patients with a variety of health problems. She enjoys being part of the healthcare team at Reliant Medical Group. “I like constantly having new things to learn as well as collaborating with other healthcare professionals – no day is ever the same.” During her free time, Marilyn enjoys being with her family and also loves to cook, garden, and paint. She also enjoys spending as much time outdoors as possible.

Dinara started her career in medicine as a registered nurse before becoming an advanced practitioner. “During my time as a nurse, I frequently cared for individuals suffering from complications stemming from preventable diseases,” she explains. “Seeing this firsthand motivated me to pursue an advanced degree. I realized that by acquiring further education, I could play a pivotal role in educating the public about making healthier choices to delay onset and progression of chronic illnesses.”

In her work at ReadyMED, Dinara strives to approach each patient with respect, kindness and empathy. “Knowing that individuals seek medical assistance during times of vulnerability, I strive to create a supportive and compassionate environment where patients feel values and listened to,” she explains. “Ultimately, I view my role not only as a healthcare provider but also a source of comfort and reassurance during challenging times.”

In her spare time Dinara enjoys being with her husband and children and their two dogs. She also enjoys traveling, gardening, listening to audiobooks, watching Eurovision, and all things Disney.

A graduate of the University of Massachusetts and Fitchburg State College, Idah has assisted patients in a variety of settings during her career, including the cardiac floor of a hospital and also in the mental health field. Idah became an advanced practitioner because she loves working with people and using her knowledge and experience to help them. In her spare time, Idah enjoys traveling and experiencing other cultures. She especially likes to cook different cuisines from around the world.

Dr. Callie Stone truly enjoys being a pediatrician at ReadyMED and helping patients with their immediate care needs. “I feel that it’s a great way to practice medicine. I really like the variety of patients and never really knowing what you are going to treat next,” she explains. “Every day is interesting.”

Some of the common problems that Dr. Stone treats include sore throats, colds and fever, urinary tract infections, and simple lacerations and fractures. No matter what the problem is, she truly enjoys interacting with her young patients. “It’s fun taking care of kids in general, and its especially rewarding for me to have a sick kid come in, be able to give some advice to them and the family, and then see them get healthier – it’s always great to make a difference in that way.”

One of things that Dr. Stone has noticed is that she is treating more kids for mental-health issues now. “Oftentimes kids and teenagers don’t outwardly say, ‘I’m stressed’ or ‘I’m depressed.’ A lot of times they come in complaining about headaches, backaches, or a change in their appetite, and you have to delve into the symptoms a little bit more to realize that maybe the problem is not something physical but something mental-health related.”

Dr. Stone enjoys the ability to utilize an electronic medical record when treating patients. “Having access to electronic medical records is really great. It makes it easy to keep track of patients no matter which provider they are seeing. It’s great to have all that information at your fingertips and have it available at a moment’s notice.”

When she is not busy helping patients Dr. Stone enjoys spending time with her husband and two dogs, which were both adopted from a shelter. She also likes to go bike riding and hiking, as well as traveling to Europe, the Caribbean and places closer to home.

Growing up, Dr. James Sullivan used to watch the TV show MASH and dreamed of becoming a surgeon one day. “Although my mother was a nurse, watching that show definitely got me interested in medicine as well as the military,” he explains. “When I was in the service, I did start medical training as a surgeon, but later decided that working in emergency medicine was more suited to someone with a growing family. However, it was a great experience being a physician in the military and something that I will always be very proud of.”

At ReadyMED PLUS, Dr. Sullivan sees patients for a variety of issues large and small. He likes to work closely with his patients and quickly communicate everything they need to know. “I like to tell patients that this is what you have been diagnosed with, this is how we are going to treat it, and this is what you need to do after you leave. People want you to be attentive to their needs, and I think we do a good job of that at ReadyMED.”

One of the reasons that Dr. Sullivan likes working at ReadyMED PLUS so much is the breadth of care he can provide. “We can perform CT scans as well as ultrasounds and provide patients a very high level of care here,” he explains. “The technology we have gives us the ability to diagnose a lot of different problems and that can really make a difference for the patient.”

When he is not busy at ReadyMED, Dr. Sullivan enjoys listening to music (he is a big Bruce Springsteen fan) as well as reading, hiking, biking and gardening. Once his children are finished with their education, he and his wife look forward to traveling more.

A graduate of the University of Connecticut and Bay Path University, Hoang has been practicing as a physician assistant since 2015.

Hoang became interested in becoming a physician assistant during his undergraduate years when he explored the medical field and had the opportunity to shadow a physician assistant (PA). “I admired the respect they received from collaborating physicians, other members of the healthcare team and patients in their communities,” he explains. “Now as a practicing PA, I really appreciate the flexibility to work in different fields of medicine and make impactful positive changes for an individual’s health. In medicine, you truly never stop learning and I have been fortunate to experience that now first hand as a physician assistant.”

Hoang enjoys the challenge of working at ReadyMED, treating many different problems each day. “I believe coming to ReadyMED can save people an unnecessary trip to the ER and help catch an illness before it worsens to the point of hospitalization,” he explains. “I think patients really appreciate the care they receive at ReadyMED.”

Hoang believes the patient is a vital part of the healthcare team. “I think the best outcomes are achieved when everyone listens, understands, and works together. I also enjoy educating patients in the community about taking charge of their preventative health, so they can work to optimize their health as they age.”

In his spare time Hoang enjoys rock climbing, running, hiking, exploring the arts, and spending quality time with family and friends.
