Nice to meet you
Hi, I'm Belysa
I was born in the Dominican Republic and came to Massachusetts, where I earned my bachelor's and my master's in biotechnology at UMass Lowell.
I've spent my career in the lab, studying how the immune system responds. That's the same system behind every allergy.
I'm also a mom. I know what it's like to stand in a grocery aisle reading a label three times. BelAllergy is where I bring those two worlds together: the science, explained the way I'd explain it to a friend.
