Our Team — The LeaderPerfect® Network
We offer clients a distinguished panel of executive coaches, business consultants, facilitators, and leadership trainers, providing big-firm expertise without big-firm fees. Here's how we do it.
We function as a virtual corporation, with only a small permanent staff led by Dr. Mike Armour and complemented by a team of Associates who form the LeaderPerfect® Network. These Associates are veteran business and leadership specialists from the U.S. and abroad.
From the LeaderPerfect® Network we put together customized teams of highly-experienced specialists to meet your unique leadership and business development needs. Because several Associates own their own consulting or coaching firms, we can tap into the added resources of these firms to serve you even better.
This business model combines high-caliber professionalism with significant cost-efficiency. We can therefore offer competitive fees without compromising on quality of service or depth of expertise. Learn more about several of our Associates below.
