Account Manager

Kassie Mastrolonardo

Kassie Mastrolonardo is an Account Manager on Fathom's Client Success team. She's passionate about helping teams deliver comprehensive marketing strategies that drive business growth through audience engagement. Whether launching new campaigns or uncovering optimizations to maximize the impact of existing ones, Kassie is inspired by moments of collaboration with Fathomers and the client teams they support. Her approach starts with a desire to deeply understand her clients and their unique circumstances, allowing Kassie to anticipate needs and work with teams to deliver solutions. 

Kassie is the queen of ice breaker questions. If she could pick one color to represent herself, she would choose rose gold. The gold represents the goal-oriented organizer who thrives on structure, and the rose embodies the creative extrovert who seeks to foster connection and learn new things. Together, that's Kassie.
