Coaching with Barbara has been one of the most impactful experiences of my professional and personal life. Being in a fast-paced profession, it is rare to thought-partner with someone who is deeply listening to you and helps provide you with the framework and mindset you need to take on complex challenges. Barbara coached me through several extremely important personal and professional decisions, and her expertise, guidance and support enabled me to not only make the right decisions, but also to adapt with the changes that followed with a new vocabulary and positive frame of mind. This partnership between Barbara and myself, and with my team, allowed us to respond with resilience to large changes and crises including a relocation and restructuring due to COVID. Barbara is professional, perceptive, inquisitive and a truly wonderful human. I look forward to our continued partnership throughout my career.
