We asked Dr. Greemberg some questions

Can you tell us more about your medical background and education?

I originally pursued medicine thanks to my best friend, who suggested I follow his footsteps. I graduated from McGill University, where I completed an Interdepartmental Honours program in Immunology and received a bachelor of science degree, followed by medical school at the University of Montreal. I received the opportunity to do an elective in pediatric immunology at Sainte-Justine Hospital, which truly captivated me. Following my paediatrics residency in New York, I returned to Sainte-Justine Hospital and completed my fellowship in allergy and clinical immunology. I completed my final training placement in immunodeficiency at the Hospital for Sick Children.

What inspired you to become a doctor?

I can’t really pinpoint the exact inspiration, but I had a strong feeling that becoming a physician was the right thing to do. I realized early on that it would be a long road. The more I met with other physicians, learned from them, and saw the positive impact that they have on people’s lives, the more I wished to be in a similar position. I truly feel blessed to have met great mentors who have taught me so much. More importantly, they were able to instill a passion for patient care.

What do you love the most about practising medicine?

Practicing medicine, especially in the field of allergy and immunology, is like solving a puzzle made of many pieces that are uniquely connected in each and every one of us.

Receiving a proper diagnosis and treatment plan for an allergy or immunologic disorder is a life changing moment for many people. The process is sometimes very complex, and can be especially stressful for parents who are worried about their young children.

As an allergist and immunologist, I’m in a unique position to help diagnose, treat, and fine-tune individual treatment plans. Caring for my patients makes practising medicine an unbelievable experience. I look forward to treating adults and children of all ages, and offering services in both English and French.

What’s your favourite part about practising on Maple?

I feel that Maple answers one of the major challenges of our time — connecting patients and physicians. This is true now more than ever, as social isolation forces us to rethink how to offer safe and accessible medical care.

Instead of my husband having to drag both kids to the hospital or walk in alone he was able to see a doctor right away and get a prescription faxed to our local pharmacy.
