The Leadership Boost
1 : 1 and small-group mentoring for leaders who are ready to grow with courage, clarity & confidence.
Because Even Leaders Need a Safe Place to Grow
The Leadership Boost is a personalized mentoring experience that helps you rediscover your purpose, refine your leadership, and move toward the goals that truly matter.
Guided personally by Sarah Elizabeth Gruneisen, Engineering Manager & Certified Leadership Coach, this program gives you the clarity, accountability, and support to lead your life and career with authenticity.
💬 Limited mentoring spots each quarter, applications by discovery call only.
When You Feel Stuck Between Potential and Action
You want to grow, but the path feels foggy.
You know you’re meant for more, but self-doubt, fear, or perfectionism hold you back.
The Leadership Boost helps you find momentum again by reconnecting you to what matters most and aligning your daily actions with it.
What You’ll Gain
✅ Clarity on your next chapter and purpose
✅ Freedom from self-limiting beliefs and perfectionism
✅ Confidence anchored in your values, not validation
✅ A plan that feels exciting and achievable
✅ Accountability and reflection with a mentor who understands
This isn’t therapy, and it’s not management coaching, it’s real, human mentoring for the person behind the leader.
The Journey You’ll Take
Three Pillars of the Leadership Boost
1️⃣ Discover Your Core Values
Identify what matters most to you and use it as a compass for decisions.
2️⃣ Release Limiting Beliefs
Explore what’s been holding you back and reframe it into strength.
3️⃣ Set and Commit to Worthy Goals
Define goals that stretch, inspire, and align with who you are becoming.
💬 Growth begins when you stop performing leadership and start embodying it.

The Discovery Call
Before we begin mentoring together, every new client starts with a 30-minute Discovery Call.
This is a relaxed conversation where we:
-
Clarify what you want to work on
-
Explore whether we’re the right fit
-
Decide together on your next best step
There’s no obligation, just space for honesty and alignment.
