Coaching Credential
In an unregulated industry, I believe that professional integrity starts with a commitment to formal, evidence-based training. My leadership coaching practice is grounded in the gold standards of the International Coaching Federation (ICF), where I am currently pursuing my Professional Certified Coach (PCC) credential. My foundation was built through the Institute for Coaching Education and the Thinking Collaborative, and is further sharpened by ongoing supervision and professional development from the KIPP Foundation. By choosing a coach with deep, supervised experience and recognized education, you are ensuring a partnership rooted in high-level results in personal development coaching and the highest ethical standards, fostering your overall professional growth.

From Kelsey Meyer, Program Manager at Google:
Working with Toni has been a truly transformative experience in leadership coaching. She went beyond simply helping me navigate a career change; she guided me through personal development coaching that allowed me to understand myself, my strengths, and my motivators on a deeper level. As an incredible leader who builds the strongest teams, I’ve learned so much about my leadership style and areas for professional growth. I can't recommend her enough.
From Kasiopia Moore-Watts, Principal of Campbell Hall, Studio City, CA:
Toni helped me navigate one of the most challenging seasons in my leadership journey through her exceptional leadership coaching. She brings not only a sense of heart and calm to every session but also a powerful clarity that inspires personal development coaching. After each session, I felt truly seen and supported, always leaving with a clear, actionable plan for my school community that contributes to my professional growth. Toni’s presence, wisdom, and authenticity make her an extraordinary coach and an even more remarkable human being.
From Candice Seagrave, Principal of KIPP STAR Harlem College Prep Elementary School
Toni has been my coach since year two of my Principal-in-Residence journey, and I truly wouldn’t have made it through my leadership path without her. Her guidance, wisdom, and care have shaped not only the leader I’ve become but also the mother and person I am today. There were moments I wasn’t sure I could stay in this work, but Toni’s leadership coaching kept me grounded, inspired, and growing. I can’t count how many times I’ve said, “Well, this is what my coach would do,” or “Let me ask Toni.” I highly recommend Antonia as a coach and mentor. She has a remarkable way of helping you uncover your authentic leadership voice and stand tall in your truth through personal development coaching. I’m forever grateful to call her not just my coach, but my amazing friend and mentor who has contributed significantly to my professional growth.
