testimonials

I’ve had the privilege of working with incredible
people—here’s their take.

"Teresa is top-tier talent. She speaks the languages of engineers, product managers, accountants, and strategic executives. She sees the whole picture, and can communicate the vision, but is not afraid to get her hands dirty to set up the systems and processes required so an organization can scale. She is particularly adept at getting large (and small) teams aligned and working towards the same goals."

Chris Millard

CEO at IBEX Consulting

"Teresa is an exceptional operator—ambitious, solutions-oriented, and deeply collaborative. She builds alignment across teams while keeping everyone accountable to timelines, consistently asking the right questions to move initiatives forward. Highly dependable and responsive, Teresa brings the clarity, ownership, and executional rigor that make her an ideal fractional operations partner."

Nicole Pollack

COO at Marcus & Pollack

"Working with Teresa at Brex was a masterclass in operational leadership. As Operations Program Manager, she was a key partner—helping prioritize and implement critical systems that enhanced the customer experience. More than a program manager, she was a trusted advisor who brought clarity, momentum, and strategic focus. Any early-stage startup would be lucky to have her as a Fractional Ops leader."
