About

Designing and leading teams since 2004.

I'm a product design leader with 20+ years of experience building products that drive business growth and inspire the teams behind them. My career runs from Emmy-winning storytelling at Newsday to leading design and product strategy at MNTN, where I've scaled teams, built systems, and shipped experiences that improved engagement and efficiency across platforms.

I shape vision, mentor design leaders, and turn complex challenges into elegant, data-driven solutions with real impact.

What I believe

Great products live where user empathy, business strategy, and execution meet.

User empathy

Research and customer insight come first, because the happy path has to feel clear before it can feel fast.

Business strategy

Design earns its seat by tying decisions to measurable outcomes in growth, revenue, and efficiency.

Executional excellence

Systems, craft, and strong partnerships with engineering turn good strategy into shipped product.

The path here

From newsroom to SaaS.

I started in 2004 building UX and product work for global brands including Microsoft, Disney, Samsung, NBC, and DirecTV. That gave me a foundation in scalable systems, advertising, and digital strategy.

At Newsday I spent 14 years leading a 20+ person team across design, engineering, and QA. We built internal design capabilities, introduced research and analytics practices, and delivered award-winning interactive work, including four New York Emmy Awards. That work contributed to a 200% increase in digital subscription revenue.

In 2022 I joined MNTN as Head of Product Design, new to adtech and eager to learn it. I've since grown the design team from 2 to 12+, built a design system that improved design-to-engineering efficiency by 30%, and led 0→1 and AI-powered product work, partnering with Product, Engineering, and GTM leadership.

What drives me

Design as a strategic driver.

What drives me is the opportunity to align design vision with business strategy: scaling teams, fostering collaboration across disciplines, and creating products that delight users while delivering measurable impact. I thrive on building the systems, culture, and processes that empower designers to innovate and organizations to grow.

At my core, I’m passionate about elevating design as a strategic driver of business outcomes, turning complex challenges into simple, elegant, and engaging experiences that resonate with users and scale with the business.
