Associate Producer

I build up great teams who build up great products || Digital Transformation, Product Management, Data Analytics, Marketing || Technology, Media, Telecommunications, B2B

I love to hit the digital “refresh” button on antiquated products, processes, and strategies. 

What does this mean exactly? All my passion, energy, and bad jokes go into making things bigger, better, faster, stronger (*cue the Daft Punk song for effect*). That’s the change I’m talking about, and love making happen.

Businesses are growing at exponential rates today. Businesses continuously need a person to lead the charge on product management and change management strategies in digital transformation initiatives. I’m that person. 

What role do I fit into the schema of things? A digital changemaker, a B2B product (or process or people) leader, a transformation strategist, the list goes on. Whatever the role, I’m here for the incredible results that happen at the intersection of technology, creativity, and business, but truth be told, I stay for the humans. 

Whether it's aligning customer pain points to functional requirements or stakeholdering with different teams to drive toward a single vision, or designing the different touchpoints in a user flow, I love every step of the transformation journey that products, processes, and people go through. What’s more, I strive to tell the story of these transformations to different audiences. There’s nothing quite like connecting to an audience through the right content and context to drive toward a common goal. 

I love talking about the convergence of business, technology and design through the lens of real-world, day-to-day digital transformation journeys. You see this is what I write and talk about. Topics span greatly, and I love the variety: leadership development, product management, transformation strategy, change management, digital marketing, content strategy, UX, personal and professional growth, productivity hacks, and beyond. 

Regardless of where you are in life, let’s connect. You have skills, know-how, passions, and a story. So do I. Let’s see where that leads us. Probably somewhere marvelous.
