Our Fellows

Nathan Blaseg, MD

I grew up in Pierre, South Dakota and attended Montana State University for my undergraduate studies. I returned to South Dakota for medical school and then completed Pediatrics Residency at the University of Utah. I am excited to be joining the close-knit community of the Dartmouth Allergy and Clinical Immunology Program. I am particularly excited by our robust oral immunotherapy program, collaborative and unique research opportunities, and Dartmouth Hitchcock’s focus on improving rural healthcare. Outside of medicine, I love all things outdoors. My wife, 2 dogs, and I love camping, hiking, skiing, swimming, and visiting all of the beautiful small towns scattered throughout New England.

Alexander Zajack, MD

I grew up in Nevada, where I also attended medical school at the University of Nevada Las Vegas. I completed my pediatrics residency training at the University of Vermont. I am super excited to be completing my fellowship in Allergy and Immunology at Dartmouth Hitchcock Medical Center. Outside of medicine, I enjoy spending time outdoors with my spouse and child, watching all kinds of sports on television, or trying new restaurants.

Brinda Prasanna Kumar, MBBS

I was born and raised in Bangalore, a vibrant and cosmopolitan city in southern India. I attended the University at Buffalo for pediatrics residency training, and I am excited to be in the Upper Valley for my fellowship. The transition to a new area and fellowship training has been made smoother thanks to the friendly and approachable attendings and staff I have met who have been instrumental in helping me adapt and thrive in this new environment. As someone who has always been invigorated by the changing seasons, the crisp air and vibrant foliage of New England are particularly exciting.

Outside of medicine, I enjoy spending time outside, hiking, traveling, reading, learning new recipes, participating in escape rooms, board games, and trivia nights, and spending time with family and friends.

Michael Tsoulis, MD

I grew up an hour southwest of Toronto, attended medical school at Stony Brook University in New York and completed my Internal Medicine residency at Dartmouth Hitchcock Medical Center. I’m grateful to be staying in New Hampshire for fellowship in Allergy and Clinical Immunology under the tutelage of the amazing faculty and staff in the section, who I have been fortunate enough to get to know over the past 3 years. I’m also excited to continue research related to penicillin allergy started in residency and contribute to other areas of active investigation within the section.

Outside of medicine, I enjoy living in the Upper Valley with its 4 beautiful seasons and all of the activities that the area offers year-round. I will never get tired of driving through picturesque mountains, whether it be on my 15-minute commute to work or to one of many hiking and swimming spots in the close vicinity!
