Glenn Mattson working with clients during an in-house session
Some of the best business, sales and language coaching I have ever received in over 20 years. You would be foolish not to hire him.
David Miller

I went from $320k of premium in 2019, $466,000 in 2020 and $820k of premium in 2021. During that same time, my GDC went from $50,000 to $275,000. Glenn played a massive role in my transformation.
Chris Kilgore, Wealth Management Advisor, Northwestern Mutual
Over the last three years my production has almost tripled — enabled me to get clear decisions, yes or no (usually yes), from my prospects at a faster pace.
Chris Kampitsis, Financial Advisor
I saw more than 20 percent growth in my business year after year… a lot of it I attribute to the Sandler process.
Roy Cook, Merrill Lynch
I have been working with Mattson and team for a few months now and it has been an absolute game changer. … We are seeing production rise in direct correlation to the amount of time we spend with them. Hands down, the best money I have ever spent for my growth.
Tyler Lank, Financial Planner, Baystate Financial
The absolute 'Best Investment' that I have ever made in myself… the Sandler Training with Glenn Mattson provides a clear, straight path to follow.
Paul G. Pakstis, Financial Planner
The dots are connected with a clear-cut sales process, supported by the psychology of sales… I don't have to be a scripted robot. I can be me and still follow the process.
Lisa Barclay, Prudential Advisors
Understanding how to create an up-front contract with a client has drastically changed my meetings with clients and my production.
Colton J. Duffy, CFP®, Director of Financial Planning, Northwestern Mutual
I have gained knowledge on the sales process utilizing the psychology of selling allowing me to close 85% of my sales. … I give them a 10 out of 10.
Robyn Ramsey, Financial Planner
The Sandler Foundations course was excellent. I rarely go into a meeting and find that it flies by. … Glenn Mattson's knowledge and enthusiasm for the material really brought it to life.
Geoffrey Burgess, President, Burgess Financial Consulting, LLC

Insurance professionals & agency leaders

He challenged me to think at a different speed and scale… and helped mold what today is now the back to back #1 Chairman's winning firm in the National Life Group.
Richard Donado, CLU, ChFC, RICP, CEO & General Agent, WealthBridge Financial Group
Glenn taught me Mind Mapping and the first time I used it I opened $100k of premium within 2 weeks on the referrals.
Brian Carlson
It was almost as if somebody had given my prospect the script of how to reply. In 30 seconds he closed himself on starting the underwriting process for life insurance.
Jared Traum, Alliance Financial Group
Glenn has taught me that advisors tend to listen more to themselves – than to what their leaders have to say. So the power of great mentoring, and great recruiting, is the power of asking great questions.
Ross Alisiani, Managing Director, Northwestern Mutual
The Sandler Selling System, emphasizing the prospect/client agenda and uncovering their ‘pain,’ has increased my confidence by creating a repeatable and solidifying selling process for me.
Winfield Marx, Prudential Financial
Glenn is the kind of coach / advisor you want to know if you truly intend to grow your business . . . and, yourself.
Bill Doer, CLU, ChFC
