Who I am:

My mom, a Labor Activist, and my dad, an HVAC Entrepreneur, made and raised me in St. Louis, where my love of BBQ, the Cardinals, and roller-skating were also born. I became a dad of 3 so that my dad jokes are now socially acceptable and my following has increased 300%. I like tie-dye.

My list of personal accolades:
• St Louis regional cub scout pinewood derby champion - 1989
• Convincing my wife to marry me - 2014
• Chicken Wing King of Redwood City - 2017
• Mr. Redwood City People’s Choice - 2018

What I've done:

I began my recruiting career in Tokyo, partnering with international companies to build engineering teams.

In 2011 I co-founded RockIT Recruiting with Jane Buescher.  We scaled portfolio companies for our partners: Khosla, a16z, KPCB, Bessemer, Battery, Greylock, Sequoia, Accel, Lightspeed, Redpoint, Norwest, NEA, DFJ, Mayfield and more.  Our team of 25 recruiters built teams for > 200 Bay Area startups.  In 2018, when RockIT was acquired, we retained 100% of our team through the first year of the acquisition.

In 2020 I partnered with Human Capital to hire their VP of Talent and continue building their Talent Advisory Council.

In 2021 I began my climate tech journey by helping Heliogen: double their engineering team, launch university hiring, build talent brand and their talent engine.

My superpowers are:

Making something from nothing, I enjoy going from 0 to 1.

Distilling a company’s essence to create a compelling employee value proposition (a.k.a. storytelling) in order to build founding teams that win.

My drive for battling climate change:

I have been blessed in life to be able to learn, meet amazing people, and do impactful work.  I feel a sense of responsibility to put those blessings to work for a good cause.  At the end of the day, if the Earth is on fire, nothing else matters.  A healthy planet is the foundation for a healthy humanity, and I need to do my small part towards this goal.

Heather is a seasoned talent acquisition leader and advisor, a tree and bee lover, and is determined to create safe, equitable, and healthy conditions for all and ensure a healthy planet for future generations.


Heather began her professional career in financial services, moved into intel and technical recruiting for government contractors around the beltway, and then transitioned into healthcare and chronic health condition management as Head of Talent Acquisition at Livongo, a pre-IPO/startup experiencing a period of hyper-growth.  Building out high-performing recruiting teams in fast-growth environments has been an enjoyable challenge for her.  She was selected to head all global recruiting for Teladoc Health after Livongo’s acquisition and came to Earth Partners from there.

Equality and diversity have always been important to Heather and throughout her career, she has created initiatives to increase workplace diversity, ensure inclusive working environments, and influence corporate culture in positive ways.

At home she is an active backyard beekeeper and gardener, with keen interests in aquaponics, indoor and sustainable agriculture, getting outdoors, and traveling to new places in the world to experience new cultures whenever she can.  She brags too much about being an early electric car owner and a novice mushroom farmer.

He is also passionate about getting outside and living sustainably. In previous lives, he filmed sloths for a Costa Rican non-profit and visited Dr. Thomas Lovejoy's biodiversity research center in the Amazon.
