Office Hours

How does this work?

I help companies ignite growth by empowering their humans, creating safe spaces for collaboration and failure. Using my unique approach as a human-centered systems optimizer, I have successfully guided high-performing teams ranging from rapid-growth SaaS startups to Broadway musicals. During the 10 years I spent working as a professional stage manager, I traveled around the country working on a wide variety of projects with creative people from all walks of life. I came to value the power of listening and storytelling, not just as part of a compelling theatrical production, but as tools to help build successful teams and projects. Those years taught me the importance of safe spaces for collaboration and failure - because sometimes the best ideas grow from the biggest flops. I’ve since applied those same principles to the tech/startup industry, helping build and scale successful Customer Success and Customer Support teams within SaaS companies. It turns out listening, storytelling and safe spaces for failure play a key role in building successful teams wherever humans work. My consistent success through this approach has reinforced my driving belief - if we take the time to listen and understand one another we build better companies, better products, and a better world. I founded Nimble Penguin to work daily towards my mission: empower everyone with the specific tools, relationships, and processes necessary to flourish.
