Elephant Energy

Who we are

Feel good in your home, feel good about your home.

Elephant Energy makes it easy to upgrade to a climate-friendly home, confidently. We’re a team full of electrification experts, helping homeowners transition to heat pumps, heat pump water heaters, induction stoves, and home EV chargers – all at once, or over time.

We deliver unmatched value, and performance you can trust– even on the coldest day. It’s true that heat pumps are hard to get right, but we take the doubt out of the equation. Our “just-right” sizing approach, grounded in building science and years of firsthand data, makes us different. A stress-free and simple installation process makes us better.

We’ve electrified hundreds of homes across the Denver Metro Area and Greater Boston with stellar results, and we’d love to help you be the next.

We’re on a mission to electrify everything, starting with homes.

Meet our founders

Hi, I’m Josh.

I’m passionate about the outdoors and using technology to help mitigate the worst impacts of climate change.

I’ve spent my career building climate-tech companies: solar energy, electric vehicles, and autonomous vehicles. I’m all about operations, technology, and product. Life isn’t complete unless there’s a Gantt chart and an answer to “how can we make our members’ lives better?” I grew up in Pennsylvania and love the great outdoors. Now, I live with my wife Rachael and our golden retriever puppy, Scout!

Hi, I’m DR.

I’ve dedicated my life towards creating a future where every person has access to no-carbon, low-cost electricity for their homes, vehicles, and businesses.

My background is in finance and strategy, first in consulting and then in sustainable asset investing. I love skiing, camping, the mountains, my dog (Griswold), and the planet with my partner, Carey. My Spotify playlist radio starts with Fight the Power by the Isley Brothers.

Heather Stephenson

Chief Storyteller

Hi, I’m Heather. A startup veteran, I’m focused on making people’s lives and homes more sustainable.

In 2008, I sold my climate company, Ideal Bite, to Disney, and I’ve been driven to help everyday people figure out how to be better to themselves and the planet ever since. I live smack in the middle of San Francisco with my husband and two daughters, serving for the past 12 years on the SF Commission on the Environment. When not working, you’ll find me gardening, hiking in Glacier Park, and hollering at middle school sporting events.

Emily Startz

Head of People

Hi, I’m Emily! I’m a climate worker dedicated to building Elephant Energy’s culture.

I believe a strong, supportive culture helps every team member thrive and contribute, driving results like electrifying and decarbonizing our world. With lots of experience creating and managing innovative, value-based programs, I love working on initiatives that combat climate change while delivering societal, health, economic, environmental, and educational benefits.

Living in Colorado, I enjoy exploring the West with my family and friends and taking advantage of everything Denver’s community has to offer.

Bryan White

Talent Lead

I’m a seasoned talent leader with a genuine obsession for my customers. I’m also a highly skilled operator, storyteller, and culture builder.

Prior to joining Elephant I spent much of the previous 4 years freelancing in support of mission-based businesses and I’m delighted to show up to work here everyday making a real impact. When I’m not evangelizing heat pumps and talking up the amazing team of people I work with, I’m probably riding a bicycle or planning an adventure to some remote destination to explore what’s unknown to me.

Kate South

Marketing Manager

Hey, I’m Kate! Lover of all creatures on this planet and passionate about keeping our environment clean. 

I’m excited to be utilizing my experience in digital marketing and mission-driven organizations to educate home-owners on how and why electrifying your home makes a big impact on our planet.

You can find me outside skiing, biking, hiking, attending live music, and of course with my 4-legged best friend, Hugo, by my side.

Jessi Sibilia

Product Marketing Manager

Hi, I’m Jessi! I call the beautiful PNW home, where I live with my family and our cats. 

After dedicating a decade to helping drivers transition to EVs, I’m now bringing my passion for fighting climate change to Elephant as a Product Marketer. My mission: helping you #electrifyeverything in your home! When I’m not working toward a more sustainable future, you’ll find me savoring a cup of coffee, painting, baking, or planning our next family adventure.

Gurbani Singh

Lead, Strategic Partnerships & Environmental Justice

Hi, I’m Bani! My experience spans consulting, finance, and business development, with a focus on tackling complex problems that require innovative, multistakeholder solutions. 

I’m passionate about building partnerships and creating financial strategies that promote equity and sustainability, particularly for marginalized communities. At Elephant, I’m excited to help scale electrification to improve environmental, health, and social outcomes. Outside of work, I love hiking, cooking, traveling, and cheering on the Ravens!

Maddi Eckert

Head of Product Ops

Hey there, I’m Maddi! I identify, in equal parts, as both a sustainability nerd and a startup fiend.

Fortunately for me, Elephant is the perfect place for both– here, I focus on building processes and products from scratch to help fuel our transition to fully electrified homes. When I’m not working or making bad electrification puns, you can most likely find me skiing or biking in the mountains with my pup, Goose!

Jade Van Horn

Operations Builder

Hi, as the heading suggests, I’m Jade (she/her)!

I am a fixer and a creator of processes by addressing inefficiencies in tooling, operations, and education. My greatest passion is sustainability, which makes Elephant the perfect home for me. I am also passionate about my three cats and one dog, hiking, and traveling!

Nora Fierman

Junior Operations Builder

Hello, I’m Nora! I bring experience in the climate space, specifically working with sales and marketing teams at startups to improve operation efficiencies. 

Elephant Energy is growing quickly and setting its footprint in the Front Range of Colorado with expansion in Boston. The product market fit is established and now it’s time to figure out how to optimize, automate and increase efficiencies. I’m excited to figure out what is and isn’t working and what needs to be fixed. These can be complex problems to solve, but solving these problems results in happier customers, which is always our number one goal!

I’ve been told my attention to detail is outstanding and my ability to problem solve while creating a fun team environment are some of my biggest strengths. Elephant Energy is growing quickly and it’s time to focus on building a really solid foundation to ensure everyone can work efficiently and smoothly, which is where I will be zooming in! At the end of the day, customer satisfaction is the most important thing, so ensuring our team works hand in hand will result in happy customers, and I’m excited to bring my contributions to a very hard working team! 

Sean Willerford

Head of Supply Chain & Logistics

Hi, I’m Sean! I’ve always been fascinated how we humans impact our planet, and how we choose to think (or not think) about it.

My varied background stretches from finance to regenerative agriculture, but I’m excited to be back in the sustainable energy space! At Elephant, I split my time between improving our operations processes and actually doing them. When I’m not working, I can generally be found either running around out of doors, playing music, or napping off the delicious meal I just cooked.

Rob Bayless

Senior Project Manager/Wrangler

Hey, I’m Rob. I have always been amazed by energy from how we make it, to how we move it, and finally how we consume it.

I am super excited to help people evolve their energy consumption while upgrading their homes. I’m an engineer by training and have worked in various engineering and consulting roles across the energy economy. Denver born and raised, I love spending time on the local trails running and hiking. I consider breakfast burritos their own (and best) food group. 

Steven Griffin

Project Manager

Hi I’m Steven Griffin! I have a background in Environmental Science and as a lifelong enjoyer of the outdoors, I’m passionate about preserving our beautiful planet for future generations to enjoy. 

As a Project Manager at Elephant I love bringing home electrification projects to life and helping shape our built environment to achieve a more sustainable future. In my free time I’m a Maker who enjoys woodworking, sewing and tinkering with electronics.

Eric Milburn

Project Manager

Howdy, I’m Eric! Before the pandemic, I worked in events and nonprofits for companies such as TEDxMileHigh and Uncharted.

Then, when events became obsolete, I transitioned my passions into construction where I worked as a carpenter, production supervisor, and project manager. As the years went on, I saw the wasteful practices of the industry which sparked an interest in energy efficient construction. It’s been a journey ever since, seeking out innovative solutions to making homes healthy and sustainable. Outside of work, I spend time with my wife and dog tending to our informal homestead where we raise chickens and grow our own food. 

Steve Crossno

Project Manager

I’ve been involved in many sectors of the construction industry over my 10 years experience.

From residential to commercial and now electrification. I enjoy the process of seeing what something is to what it can become. Electrification with Elephant Energy provides the opportunity to leave a legacy beyond more than just us and help build the way to a more sustainable future. When I’m not changing the world I enjoy fitness, playing sports, and using what athleticism I have left with my wife and 2 kids.

Enrique Santiago

Project Manager

Hi, I’m Santiago! Working at startups is my passion and finding ways to keep the air around me clean if my lifeline.

Since my introduction to Hobbiton in my youth, I’ve cherished a deep connection with nature. An avid hiker, sailor, cyclist, and explorer, I find comfort in the outdoors alongside my loving wife and faithful dog. This passion for nature has inspired a career dedicated to creating a cleaner, more sustainable world. At home, I nurture a thriving vegetable garden and tend to 16 chickens, embodying my commitment to sustainable living on a personal level.

I am excited to be here because elephant’s approach to electrification is customer and tech focused. I believe that both my tech and carpentry background will help me to make customers feel comfortable and assured and also bring innovative ideas to my team as to how to be more efficient and streamline processes.

Chris Losco

Project Manager

Hi, I’m Chris! My passion is in finding ways to make people’s daily lives and activities less harmful to our natural environment.

I have been in the renewable energy project management space for about 6 years and feel very grateful to be doing work that is helping to make our consumption of energy cleaner and more diverse. Outside of work, I can be found onstage in local community plays and musicals, and playing recreational hockey for Boston-area leagues.

Tia DeHarpport

Project Manager

Hey there, I’m Tia! I’m stoked to be here at Elephant making a dent in decarbonization.

I’m happy to be utilizing my background in construction project management to help folks like you transition your home away from using fossil fuels. In my free time you can find me outside skiing, hiking, or biking, or exploring Denver’s coffee shops, book stores, and live music venues.

Graeme Hoste

Project Manager

Hello! I’m Graeme Hoste. I have a background in mechanical engineering and the utility-scale solar industry.

I’m passionate about climate change and environmental justice. I love having an impact on these large-scale problems one home at a time, while also helping homeowners feel healthier and more comfortable in their homes! In my free time, you’ll probably find me outside with my family: playing sports, cross-country skiing, camping, or hiking.

Joe Shannon

Project Manager

Hi, I’m Joe! I’m excited to join Elephant Energy, bringing a background in project management, operations, sales, and customer service.

For 13 years, I worked in professional sports, and for the last 5, in the home services industry, where I fell in love with heat pumps and electrification!
When I am not fighting the good fight you can find me enjoying time with my beautiful wife, our adorable two daughters, and our German Shepherd. My other passions include sports, music, and the great outdoors.

Before Elephant, my background was in environmental consulting and renewable energy operations and sales. I’m keen on solving customer’s problems and guiding them to the best solution possible.

Dave Heal

Home Comfort Advisor

Hi, I’m Dave! I became a home electrification true believer shortly after buying my first home.

My background is in software sales with a quick pit stop to help build a small publishing company. I enjoy running uphill, reading large books, and hosting home concerts, though not at the same time. I donated a kidney to a stranger and would love to talk to you about it.
