Our Story

How We Started Providing DISC Profiles Training

PLI’s co-founder, Justin Mitchell, discovered the power of business coaching and DISC profiles firsthand when he hired a sought-after leadership coach, Trevor Throness.

Trevor’s systematic approach led to 50% consecutive year-over-year growth for Justin’s real estate business, attracted top talent, and improved team unity, focus, and purpose. Seeing the transformative impact on his business, Justin realized that DISC Profiles training could help revolutionize companies across different industries.

With this deep understanding of the potential and power of using DISC profiles in leadership and training, PLI was founded with a vision to provide accessible solutions that unlock the success of businesses of all types and sizes.

The DISC Profiles are now used with businesses PLI serves from Fortune 500’s to local small businesses. PLI aims to offer the best in training at an accessible price and support companies in fully integrating DISC profiles within their business.

The PLI program was invaluable to our network.
The range of topics delivered, the open dialogue, experience, and examples that PLI brought to each session were outstanding and provided a path for our Franchisees and Managers to look at leadership, coaching, and connecting with their teams in a new light. Many have implemented these strategies in their bakeries and have seen immediate results.

Highly recommend to help your team move forward
We have locations around BC and Alberta, so getting people on the same page can be very difficult... Until now. Our entire management team and location managers take the same great courses and then meet monthly online with our coach to apply it to our situation. People are engaged, the courses are excellent, we love our coach, and we are all learning together!

The result has been a transformation of our culture. 
We decided to implement PLI's strategies across the country in over 150 locations and over 3500 employees.  The result has been a transformation of our culture.  People's lives have been positively impacted - professionally and personally.  Morale is high and sales and profits are up as a result.

We’ve learned how to fix ongoing personnel issues once and for all
The roadmap laid out set our business up to quintuple in sales.  We've learned how to fix ongoing personnel issues once and for all, attract top talent, and spend our time focused on results, not internal staffing problems.  I highly recommend PLI to you - it's worked for us!

I had no idea that running a business could be this fun!
In less than 18 months of working with Trevor, he has transformed my business from being average to exceptional, where mediocrity is not acceptable, where being great is standard.  Working with PLI has allowed me to realize my dream of not simply owning a job, but owning a business.

Our culture has taken major steps forward this year
Our culture has taken major steps forward this year with Trevor’s help.  He is funny, relatable, and his tools are very very practical and have helped us focus and upgrade our teams throughout our retail network. Trevor recently spoke to an employee group, and one person remarked, “I could listen to Trevor all day.”   We would highly recommend Trevor.

The results have been remarkable
At first, we resisted, “This just won’t work with a law firm.” But we persisted and the results have been remarkable: our client base and profits have steadily improved, and staff engagement and morale is the healthiest its ever been.

Helped our fast-growing business become what it is today
I've experienced PLI's approach first hand and it's been crucial to sustaining our growth.  I can't imagine a business that wouldn't benefit greatly from his help.

Provided practical ways to make positive changes
Trevor was incredibly well-received by the entire organization. He was able to articulate people issues that many of our franchisees were experiencing and provided them with practical ways to make positive changes. We have implemented the Star Chart tool across the organization and see it as vital to building happy, effective teams.
