Facing our greatest fears is the pathway to the kind, inclusive, and sustainable world we all long for. Imagine holding a secret so big that sharing it could mean destroying the life you built and hurting those you love. Imagine sharing and embracing a secret so powerful that it could transform your life, your relationships, and how you see and lead in the world. As one of Canada’s most senior and recognized corporate executives, Katherine Dudtschak had a masculine name and appearance that did not reflect her truth. She had built a life of material success, yet something essential was missing. Katherine was born to immigrant parents who came to Canada after surviving World War II camps. Her early years were marked with post-war trauma, financial stress, and learning difficulties. Fueled by a passion for a better life, she became a loving parent to four children and a top executive at Canada’s largest bank. But everything changed in a moment while visiting her daughter’s university dorm. A gender inclusivity poster spoke to a truth she’d buried deep inside. She saw Katherine: the woman and the essence of who she had always been. At 50, she affirmed her gender, coming out as Katherine to the corporate world in front of 80,000 colleagues. Her courage proved that authenticity and leadership are not only compatible but essential. Katherine ignited change, inspiring a more inclusive and compassionate approach to leadership. She amplified voices from all walks of life, especially those who knew hardship, adversity, and the feelings of not belonging. She created space for human uniqueness to be seen and valued as a vital ingredient in building the kind, inclusive, and sustainable world we long for. Sincerely, Katherine. is a story of resilience, self-love, and the profound impact of leading with authenticity, inclusivity, and purpose. She inspires each of us to foster a harmony within ourselves, and with each other and the natural world we are part of and share. “One of the most sacred experiences a human being can navigate during their lifetime is a deep communion with their true self. This is far from an easy task. Katherine Dudtschak is a shining example of courage and authenticity as she redefined the notion of true leadership along the way in both her personal and professional life. Her story might not be yours, but don’t be fooled, its lessons are universally ours.” ―SOPHIE GRÉGOIRE TRUDEAU, global speaker and bestselling author of Closer Together “ Sincerely, Katherine. is not just a memoir―it is a masterclass in courage, authenticity, and leadership. Katherine Dudtschak’s words are not just a personal story―they are a call to action. Sincerely, Katherine. reminds us that when one person finds their voice and speaks their truth, it creates space for all of us to grow, to listen, and to evolve together. This book is a tender and transformative contribution to a more compassionate world.” ―DR. ROBYNE HANLEY-DAFOE, award-winning author of Calm Within the Storm and Stress Wisely “ Sincerely, Katherine. is a heartfelt story of Katherine Dudts chak’s incredible personal journey mixed with life lessons and leadership perspectives for the future. I certainly appreciate how hard it is to share one’s personal journey so publicly in the hope of making life better for others, as Katherine has in this book.

This book revealed so much I had not known about the life, challenges, and insights that unlocked the woman who never ceases to impress me. I highly recommend Sincerely, Katherine. for not only Katherine’s generous sharing of her experience, but also her reflections on how inclusive leadership can have a fundamental impact on individuals, organizations, and society.” ―ANTHONY OSTLER, president and CEO of the Canadian Bankers Association and proud parent of two gender-affirmed children “Katherine Dudtschak’s story is inspiring and motivational. She is one of the bravest people that I know. Her insights and lived experiences will hopefully help others on their own journeys of self-realization and fulfillment.
