Stacee Mandeville: Founder

Since 1999, Stacee has delivered communication skills coaching to executives around the globe. She specializes in helping people structure content from an audience focused point of view, thereby increasing engagement, influence, and buy-in. She also helps unearth clients innate vocal power, manage undermining physical habits through body language control, and elevate overall "executive presence" when selling, presenting, or pitching under pressure. She has had the pleasure of working with individuals in myriad of industries, including Merck, HP, General Electric, JPMorgan, Deutsche Bank, Verizon, A&M, Citigroup, Barclays and Levi's. She has used her accumulated experiences with clients from all over the world, combined with her theater background, to create the Red Leaf Coaching methodology. 

Working with Stacee, you will find she has an engaging but no-nonsense approach. Since managing work-life balance is a constant struggle for most people, she strives to make her coaching targeted and efficient, and gives her clients the tools to grow as quickly and simply as possible. The Red Leaf Coaching methods were designed as an answer for companies who know that the ability to communicate with authority, passion, and clarity is a paramount foundation skill, but who simply don’t have the time to devote to lengthy, ongoing coaching. 

Stacee was classically trained in theater at New York University, (B.F.A.) and has additional experience in team building, professional development, influencing, networking, accent modification and mentoring.

Back to Courses

This was the best training I have been through; I had never had training like it. So specific, targeting our issues and giving concrete tools to help us adjust. I love the one-on-one aspect of it-the private coaching and video review is the most helpful part of the course. I would highly recommend this training.
