For my entire 17-year tenure at RadioShack, Michael Castelli has set the gold standard; developing the most successful teams, creating the most important programs, and winning the most awards. Most recently, as his direct report, I was able to benefit directly from his passion for excellence. Michael is a solutions oriented leader who truly sees every challenge as an opportunity.

Michael is vigilant in his attention to the shadow he casts as a leader. He always asks questions and actively listens to even the newest associates; valuing all team members as not just employees, but as people. He teaches all new leaders that to lead, you must first respect.

I worked closely with Michael when he was a RadioShack executive....he was a quality partner that I highly respected....he was constantly in the field inspecting what he expected, all the while seeing how he could help his team achieve more. Michael was tough but fair.......he is a very strong executive leader

Michael was one of the most successful Divisional Vice Presidents at RadioShack. He was loved, admired and highly respected by his team and his peers. Michael is always upbeat and does't even understand the meaning of failure. He is a great team player and leader and mentor to many. He will be an asset on any team....but only if you want to WIN!

Michael Castelli served on the Board of Directors for The Women's Shelter which later became SafeHaven of Tarrant County following a merger. As the CEO, I found Michael instinctively understood his role to be that of leveraging his network to benefit our clients, domestic violence victims. He provided extraordinary support for the agency during his tenure and even beyond. The leadership skills he displays professionally worked equally well in the board room. He became a true advocate for domestic violence victims just as he is a true advocate for his company, staff and business clients.

Few people have the opportunity to meet someone and in such a short period of time, know that this individual will be a lifelong coach and mentor.

Regardless of the circumstances, we worked together professionally, with the goal, if it came down to it, of providing a smooth transaction for everyone. It was a very positive working experience. Michael is a leader in all aspects of the word. He is relentless, smart, and talented and is an expert and leader in the wireless and telecommunications industry.

His tireless energy and infinite enthusiasm is a motivating force. He’s dedicated, passionate, and driven and one of the best sales leaders I know in the industry.

I have had the pleasure of working with Michael for several years. Michael gives clear direction and the "why" behind initiatives to execute results. His dedication to helping his teams grow and succeed is evident in everything he does. Although these are all great traits, my favorite is that he always starts every conversation asking about you and your family. Michael truly cares about those in his life and wants the best for everyone. He is a dynamic, passionate, hands on leader with a "people first" mentality.
