Arizona Growth Advisors is both a peer group and real-life experience MBA rolled into one. The monthly meetings have given me an opportunity to reflect on our business plan, bounce ideas off of peers and talk with experts who have sat in my seat before. I can’t speak highly enough of my experience since joining.”
— Sarah Weiss, COO, Elite Roofing Supply
I was skeptical at first. I soon discovered, though, that instead of being “alone” in the world, there were others in my same position, facing similar challenges. When we began working through challenges as a group, I felt like a door had opened. I saw ways to become a better leader and when I put what I learned into practice, people in my professional and personal life took notice!”
— Dan Sloan, COO, Redcat Racing

Mary facilitates roundtables that help COOs & Operations Leaders become more effective leaders and achieve their growth goals.
