Marissa joined Seer in 2016 and now serves as Chief Delivery Officer, based near Seer's HQ in Philadelphia. She leads Seer's entire delivery engine (SEO/GEO, Paid Media, Analytics, Creative, and Agency Operations) ensuring the organization operates as one high-performing system across financial health, operations, and client experience. She partners with division leaders to align teams around shared standards, and drives the evolution of Seer's offerings to match client needs, market shifts, and AI-driven transformation.

Marissa's path to this role began in building out Seer's Client Services function, leading the account leaders and project managers who manage Seer's largest enterprise partnerships. Her focus on bridging Client Engagement, Project Management, and Operations to build scalable workflows and an enhanced client & team experience now extends across the full breadth of delivery. She's especially focused on ensuring Seer's teams are equipped not just to use AI, but to translate its value into real outcomes for clients.

She's proud to help shape Seer's structure as the company grows, and she and her teams remain driven by the same instinct that's always defined Seer: uncovering what others overlook, and harnessing curiosity to delivering client value.

Gift of Life is a meaningful organization to me, as my wife is a kidney donor to my step-brother. I am fortunate to live close to Gift of Life Howie's House where I can give back by providing nourishment for those giving or receiving an organ donation and need a place to stay, especially since folks travel a great distance to receive the quality of healthcare that Philadelphia has to offer.
