Senior Leadership

Brenna Garratt
Chief Executive Officer

Over the past 20 years, Brenna has guided dozens of B2B companies in building successful brands that raise their enterprise value. She has a knack for ‘seeing’ brands and guiding them to realize their strategic growth goals. She has worked with many leading private equity firms and prominent brands such as Accenture, Genpact, Mercer and RiverStone and countless other niche B2B businesses. When she’s not in the office, she’s almost certainly sailing with her husband on their beloved sailboat ‘Dazzle’.

Stacy Colonna
Chief Operating Officer

Stacy has decades of management and communications expertise and oversees Sustena’s operations, specifically production, processes, and procedures. She has an uncanny ability to ‘see around corners’ and anticipate challenges to keep our workplace and our clients’ projects running smoothly.

He has led many successful national branding and re-branding efforts across multiple sectors including technology, insurance, financial services and construction/building industry. A purveyor of fine craft beef jerky, Bryan calls Brooklyn home where he’s either coaching his daughter’s champion softball team or “letting” his son score on him on the soccer pitch.

Stephen Strigle

He excels at analyzing research to uncover key business insights and then bringing them to life in clearly articulated prose.
