What people are saying about John…

“I was a brand new executive director when John Tarvin contracted with us to create our strategic plan.  He was kind, thoughtful, helpful, and thorough.  We have a great product that we use and monitor routinely as a result of his diligent work with us.  I would recommend John to anyone looking for a talented advisor to help them navigate their strategic planning process.”

– Rebekah Gewirtz, Executive Director, MPHA

“As a new Executive Director tasked with implementing change in a 15-year-old organization, I faced a number of obstacles—including some borne of my own leadership and management style. John’s professional coaching helped me identify the areas I needed to improve in order to move my organization forward.”

– Robert Beatty, Executive Director, Atlantis Charter School

Throughout the demanding chartering process, John provided me with high-touch support, which informed our school design and our strategies for board development and fundraising. His extensive expertise was tapped repeatedly, and his responsiveness was superb.”

What people are saying about Erin…

“I have been a part of creating many strategic plans over the years for both schools and non-profit organizations, and despite our having to gather remotely via Zoom this time, I have to say that Erin was the best facilitator that I have ever worked with for this kind of process. Her commitment and attention to detail from the pre-work, during the day-long presentation, and as part of the post-meeting follow up was flawless, engaging and always professional.  I was so impressed with her facilitating and presentation skills that I have given her a most enthusiastic recommendation to my fellow state school counselor association leader colleagues across the country who may be in need of similar services.”

– Bob Bardwell, Executive Director, MACSA

“Erin is thoughtful and engaging. She listens attentively and repackages my jumble of emotions and ideas into succinct themes which help me see that I am greater than I knew I was with more potential than I ever dreamed. She is a ferocious cheerleader, helping me celebrate my successes, while not shying away from asking me what is getting in the way of my ability to accomplish MORE!”

– Rebecca

“I’ve been able to benefit from Erin’s coaching professionally for years as she supported my growth as an organizational leader. Most recently she has helped me navigate a significant life transition. I often find myself coming to her with a lot of questions, limited clarity, and at times, a lack of confidence. I leave with tangible and meaningful next steps, and the belief that I can actually do this! Her ability to listen with intention, ask the right questions at the right moment, and brilliantly distill your meandering thoughts into clarity is unmatched.”
