ELMM: Founded for all by an Engineer, Leader, Mom & Mentor

About ELMM Coaching

What sets ELMM apart

Our values

  • Our first core value is flexibility. We champion the engineering concept of design, build, test — reminding us daily to stay flexible and keep iterating.

    Flexibility shows up in our product offerings, our customizable workshops, and our commitment to keeping every conversation client centered.

  • We are engineers.

    This comes with a love of star wars and confusion over why tiktok exist.

    It also comes with an ability to systematically work through the toughest problems with clarity of purpose.

    From our robust ELMM Framework to coaching packages focused on overarching measures of success, we use the very best of engineering to thrill our clients!

  • We are driven by our passion to elevate under-represented voices in STEM. With this, we know our clients face a a 17-40% pay gap based on gender, race, and other intersecting identities.

    If you want to be coached, we will find a way to make it work.

  • “Hard is hard.” Being a working parent is hard. It doesn’t matter your job, your support system at home, or how lovely your kids are.

    We support working parents navigating work-life balance, mom-guilt, and priority management.

    We’re there for you when you’re debating if you really need to join the PTA.

    With 3 out of 10 women leaving STEM after having children, we know this phase of life is hard. We are here to listen. Together we can find success in professional AND personal life.

  • It happens time and time again…

    We start talking about career progression or tools to navigate your career, and then people start asking about mentors.

    What are they?

    How can they find one?

    Our core mission is to build community and raise awareness of non-traditional journeys in STEM. Mentorship, aka trusted professional partnerships, are a critical key to making that a reality.
