From Hindrance to Performance
Diagnose What's Getting in the Way. Discern What to Do Next.


When performance falls short of expectations, our instinct is often to act quickly: adopt a best practice, try something new, push harder, or abandon an approach that doesn't seem to be working.
But a performance gap tells us that something isn't working. It doesn't tell us why.
In From Hindrance to Performance, Human Performance Advisor Ariel (Kopac) Stumpf challenges audiences to look beyond symptoms and rethink how they respond when results aren't matching expectations.
Through relatable stories, practical insights, and an actionable approach to human performance, Ariel explores the common ways we misdiagnose performance gaps and equips audiences to identify what's actually getting in the way before deciding what to do about it.
AUDIENCES WILL LEARN TO:
Recognize common reactions that keep individuals, teams, and organizations stuck
Look beyond visible symptoms to better diagnose the source of a performance gap
Distinguish between barriers that require different responses
Apply greater discernment rather than blindly relying on best practices or familiar solutions
Respond to hindrances with greater clarity, intentionality, and effectiveness
Better performance starts with a better diagnosis.
One Keynote. Relevant to Your Audience.
The challenges behind performance gaps vary by industry, organization, and role. The principles for addressing them don't have to.
From Hindrance to Performance maintains a consistent core framework while stories, examples, and applications can be tailored to the context of your audience—from business development and leadership to team performance and organizational growth.
Available for in-person and virtual keynotes.
