I work 1-on-1 with entrepreneurs, tech professionals, and creatives who want to perform at a high level without burning out. Most of them are already doing well, but feel scattered, stuck, or like something’s missing.

Through non-directive coaching, I help them slow down, think clearly, and reconnect with what really matters, so they can make better decisions, get focused, and move forward with more energy and intention.

We work on things like:
• Finding clarity during transitions or growth phases
• Managing energy and mental load
• Building healthier routines and habits
• Navigating stress and overthinking
• Reconnecting with values and long-term vision

It’s not advice. It’s space to think, reset, and unlock your own answers.
