Interests and Expertise

Mary Beth comes to work every day continuously motivated by her colleagues and feels it’s the extraordinary talent that drives the company forward.


“The scientific prowess that BMS is known for is what originally captivated me and led me to pursue a career here,” she said. “However, as I reflect on my time at BMS, I’m constantly reminded of why I choose to stay here. The people that I work with show me each and every day how incredibly talented and dedicated they are. We have some of the best people in the industry working with such passion and vigor. It will never fail to inspire me.”  


When Mary Beth isn’t connecting with those around her at work, she enjoys spending her free time with her family, especially enjoying quality time with them at the beach.
