Meet The Team

Passion, commitment, community

We’re a team of individuals fully committed to the vision of EarthHero.
Together, we can leverage conscious consumption into positive action and wide-reaching impact.

Ryan Lewis

Founder and CEO

A dad, husband, nature junky and entrepreneur, Ryan recently left behind the more traditional world of business to follow his passion for environmental sustainability. With two decades of ecommerce experience and a desire to help tackle our society’s harmful consumption norms, EarthHero was born. “We want to make sustainable shopping the new norm. I imagine a day when every time you want or need to buy something, it’s sustainably made. It’s a movement that’s already underway. We aim to accelerate it!” When not in the office you’ll find him outside biking, hiking, snowboarding, trail running and playing with his family. 

Jeff Day


Jeff joined the EarthHero team after a long history working alongside Ryan. From the first conversation around the idea of EarthHero, Jeff knew it wasn’t a matter of IF, but WHEN he would get involved! Jeff officially joined the EarthHero team full time in September of 2018. With over 20 years of experience in eCommerce, Jeff has worked for some very large organizations but feels more at home in a small, scrappy office with a ‘family’ culture like he found at EarthHero. He’ll admit, he’s once experienced eco-confusion when faced with the 7 different trash receptacles outside of a Whole Foods. But, now, Jeff is diving in head first into spreading the sustainability movement. He’s excited to be a part of the team, and to make EarthHero a household name for everyone.

Becki Woythal

Sustainable Sourcing Manager

If anyone in the office ever has a question about sustainability, Becki is our girl. She has always felt a strong urge to change the status quo of our wasteful culture. Growing up in rural Wisconsin, she recognized a need for easier access to information about sustainability. After graduating from CU Boulder with a degree in Environmental Studies, she continued her sustainable focus through community outreach and environmental education. Her work in Zero Waste event management at Eco-Cycle, a local non-profit recycler, allowed her to understand others’ barriers to environmentally conscious living. This inspired her to make an impact by promoting change in the way we produce and consume everyday items. She aims to live in a way that inspires others to adopt more sustainable lifestyles. When she’s not working, Becki enjoys weekends in the mountains, a good hike, and anything involving food, friends, and music.

Hannah Hester

Brand Marketing Manager

Hannah immediately knew that she had found something really great when she happened across EarthHero. Surrounded by a team of forward-thinkers, every day is a crazy and new experience that really can change the world! In the office, Hannah’s the planner. From scheduling team meetings to pulling together a kick-a** team of interns, she’s the one who keeps us all on-task. She’s proud to be a part of this movement where her work can really make an impact. When she’s not working, there’s a 90% chance she can be found skiing.

Callie Weldon

Sustainable Sourcing Manager

Callie is a sustainable fashion guru and lover of natural materials. Aside from being a self-proclaimed supply chain nerd who enjoys researching low-impact materials, she’s passionate about making environmentally-friendly sourcing a no-brainer for companies of all sizes. Callie holds a Bachelors in Fashion Merchandising and an MBA in Global Social & Sustainable Enterprises. She’s especially drawn to global supply chains and previously lived in Peru while working for a women’s fair-trade textile cooperative. She’s stoked to be managing the Apparel, Accessories, Kids, and Baby categories at EarthHero! ‘It’s definitely an alignment of core values around sustainability and responsible sourcing (and love for office-dogs)’ A typical Colorado-gal, Callie can often can be found with her dog, Bodhi, in the mountains hiking, climbing, or practicing yoga.

Juliet Payne

Product and Marketing Content Coordinator

When Juliet became our first intern back in 2017, she never imagined how much EarthHero would grow in such a short time. After graduating from the University of Colorado Boulder with environmental studies and atmospheric science degrees, Juliet joined the team full time–working on anything and everything from social media and influencer marketing, to product data and uploads. When she’s not running around the office, you can find her doing yoga or at home with her two cats (total crazy cat lady!)

Ellie Mersereau

Customer Service and Administration Specialist
Ellie had only been in Boulder for two weeks when she heard about EarthHero. She knew immediately that she HAD to get involved. She recently graduated from Bowdoin College with a degree in Environmental Studies and Visual Arts, which may seem like an odd combination. However, the two certainly come in handy when she’s answering customer questions over live chat or making orders look perfect (sometimes at the same time!).
When she’s not in the office, Ellie is likely blending smoothies, reading about herbal remedies, or run-walking in the great outdoors!

Cullen Aulwurm

Supply Chain and Operations Specialist

Cullen was born and raised in Colorado and moved to Boulder from Fort Collins for University. During his last semester he interned with EarthHero as a sustainability and operations intern and, after graduating from CU with two degrees, Operations Management and Environmental Studies, he joined the team to manage our warehouse and supply chain. Cullen is passionate about how business can affect change in our modern world, and cares deeply about the ecosystems and people that live on our planet. When he isn’t crushing it in the office, you can find Cullen hiking, running, reading a good book, watching documentaries, and playing video games.
