Mariah Pulver, President

Mariah is originally from Tucson, Arizona. After graduating from Texas Christian University with a Bachelor of Arts in Journalism and Political Science, she joined Textron, which brought many opportunities and moves along the east coast! Mariah finally landed in Baltimore and has been here for five years. She's had various roles in Marketing & Communications, and currently plans events and trade shows around the world. When not studying for her MBA, Mariah enjoys running, reading and spending time with friends. 

Sean Doughty, Chief Financial Officer

Originally from the Northwest, Sean received bachelors' degrees in English and Spanish from the University of Hawaii at Manoa and spent three years teaching abroad in Spain. Upon returning, he earned a master's in Hispanic Literatures and Cultures from The Catholic University of America. He began working with Johns Hopkins International Patient Services in Baltimore as a patient account manager in 2015 and, congruently, began managing the contracts and finances for a tech start-up in 2017. When Sean isn’t working, you’ll likely find him studying, but, assuredly, he is dreaming about someday having time for his hobbies: traveling, reading for pleasure, writing, playing the guitar, doing any kind of sports activity (especially surfing, snowboarding, rock climbing, basketball, or softball).

Shay Etches, Chief Marketing & Communications Officer

Mason Smith, VP, Washington, DC Campus

Mason Smith is a graduate of Morehouse College with a Bachelor of Arts degree in English. A native of Odenton, Maryland, he has been living in Fairfax, Virginia since 2017. Mason works as a technology sales representative for Oracle supporting state and local governments to solve business challenges. Mason landed at the Smith MBA program partly due to his family's recommendation as well as the school’s reputation for success. His sister is a graduate of UMUC, and his mother is a graduate of the University of Maryland at College Park. So one could say “the writing’s on the wall” for him to continue the tradition. In his free time, he enjoys cooking, yoga, fishing, and spending time with his younger brothers. Mason is excited to serve on the PTMBAA board and looks forward to fostering a more inclusive and valuable experience for his fellow students.
