Hi, I’m Katheryn!

Leadership Coach. Self-Help Fanatic. Your Future Biggest Fan(!)

Since 2016, I have coached and trained hundreds of leaders in global organizations including Fortune 500 companies, especially in the areas of Leadership, Cross-Cultural Education, and Wellness.

As a half-Japanese, half-American Executive Coach who comes from a family of public bath house (sento) owners, I draw on the ancient Japanese practice of public bathing to guide today’s leaders in showing up authentically, feeling heart-centered, and leaving a lasting legacy.

My personal and professional experiences led to the birth of my core philosophy, The Sento Mindset.

Testimonials

"Katheryn Gronauer came recommended from so many online and individual sources that I would have continued in my foolish ways not to hire her. And I'm glad I did. Not only did she help me sort out the jumble of ideas and hopes that were milling around in my head, not only did she offer concrete activities to help me extract those that were the best match for my long-term path, not only did she assign homework after each meeting with attainable goals, she did all of those things with personal attention to my specific situation."

Tim, Software Developer
“I cannot recommend Katheryn enough. I have been working with her for years. I was looking for someone who could help triangulate my work, life and passions and make sure they all made sense by addressing them as a whole. She is a great listener and always makes sure you start and walk away from each meeting with food for thought.”

Michael, Director
"Katheryn's coaching has not only helped me feel more positive, but it is also guiding me in the direction of success. I was struggling to feel like a good culture fit at my company and she helped me see opportunities. She has helped me to organize my thoughts and clarify what I need to do in order to have a concrete image of what I want to be and how I want to be successful. She also helped me to think about how I could better talk to my manager and global leaders to make that happen. Katheryn is very helpful not only as psychological support but also as an executive coach.”

Rie, HRBP
"A lot of what I have learned is that I have control over my reactions, even when it's taking a pause beforehand, and that makes me feel empowered; it's all in my control. The biggest unlock with me and coaching is having someone reframe my thinking in real time. Katheryn has been a great support. I feel heard and acknowledged, and felt her coaching is very targeted.”

Anne, Director
