“I was very fortunate to come across Manager Tools over 10 yrs. ago and I've continued to listen ever since. I've also attended the in-person training and have purchased multiple products...each has delivered value far in excess of its price. It's rare to find such specific, actionable, and effective guidance...and I usually find opportunities to apply this guidance within days!” Graham Cochrane, Senior IT Manager, TD Bank Group

“Mark Horstman taught me a vital lesson about management: there's no voodoo. It's all about relationships, behavior and results. If you want the latest management trends and lingo, don't read this book. But if you want to learn how to act consistently and effectively, buy the book, read it, and immediately share it with your entire organization.” Michael J. Reitz, Executive Vice President, Mackinac Center for Public Policy

“Having been trained as a scientist, the manager tools as available via podcast and conference have always appealed to me for their rational construction and the analysis that accompanies their introduction. I am excited to have the basic tools available now in book form where they can also benefit people that are not listening to podcasts. When I am asked how I learned what I do, I will be referring people to this written version in the future!” Rob Hooft, Manager, ELIXIR Netherlands

“The Effective Manager is a must read for every leader. I’ve been following the Manager Tools guidance for almost four years and have experienced a measurable increase in job performance and promotion frequency. This book is a bargain at $10,000.” Robert Greiner, Manager, Pariveda Solutions

“Mark Horstman's The Effective Manager represents best practices. Managers and organizations can and should adopt them with confidence. Mark provides a clear blueprint on how better relationships will drive better results. I know from direct experience they adopt very well in academic and non-profit environments, and I only wish I had adopted these practices twenty-five years ago when I started in industry. I will keep several copies on hand to give to colleagues, similar to my practice with Peter Drucker's The Effective Executive.” The Rev. Raymond Bonwell, Director, Organizational Training & Development, The Board of Pensions of the Presbyterian Church (USA)

“I started listening to Manager Tools eight years ago when I was a direct in a team. After eight years I have been promoted into management, senior management, and finally into Directorship . This year I will become a Managing Director. The rapid advancement of my career is due to the implementation of the behaviors you will find in this book.” Stephen Robinson, Associate Director, WYG

“The methods I've learned from Manager Tools have been invaluable to my career as a professional manager. Their specific, actionable guidance has helped me to effectively lead teams of both technical and non-technical professionals, and I wouldn't be where I am today without them! The Manager Tools Trinity™, and especially one on ones, are the simplest and most effective management tools around.” Andrew J. Sikich, PE, CPESC, Illinois Civil Manager, Ruekert & Mielke, Inc.
