What Clients Are Saying

~~~

“Stephen helped me clarify my priorities and act with confidence. I lead with less friction and better results.” COO, FinTech

“I was burned out and losing my edge. Coaching with Stephen helped me reset, lead at a higher level, and reconnect with why I do this work. The impact showed up in my performance and in my life.” Head of Surgery, Top Teaching Hospital

~~~

“I knew what I needed to do to grow my business, but I just couldn’t get myself to do it. Stephen helped me face what was holding me back. Bit by bit, I got braver. I started showing up differently with clients, partners, and myself.” Sales Exec, SaaS

~~~

“Coming out of a startup, I knew how to build, but I wasn’t sure how to position myself back inside a company. Stephen helped me clarify my value, tell my story, and approach the next chapter.” Product Manager – Renewable Energy

~~~

“I am the glue that connects diverse teams (I lead 4 teams, 122 employees), but as a “jack of all trades”, I have felt oddly unqualified. Stephen helped me get out of my head and embrace my value. I changed how I approach meetings and interact with the c-suite. He also gave me the push I needed to create the ‘artifacts’ I typically avoid”. Senior Director, Consumer & B2B Electronics Company
