Justin Winstead

CEO & Co-Founder

Growing up in a rural area and with meager means, Justin could have easily given up on his goals. Instead, he chose to use his circumstances as motivation to create a better life for himself. He pursued an education, attended seminary, and started his own successful business. Justin's story is an inspiration to anyone who has faced adversity in their lives, showing that with a clear purpose and a productive mindset, anything is possible.Today, Justin is a leader in his field, having sold his successful insurance company to pursue his passion for coaching and consulting full-time. Through the Improver Group, Justin is helping other faith-driven business owners and leaders to achieve their goals and reach their full potential. His insight-focused coaching, consulting, and training has already helped countless individuals and companies to be better versions of who they were meant to be.
