Client Testimonials
“Ed has helped us learn and implement EOS, a single operating system, for our 35 year old, 40 person professional services firm. The results are impressive; using one system allows us to spread it and teach it to all our employees over time and it continues to gain traction. One systems keeps it simple and efficient. Ed’s energy and passion make it fun!
I am also a Vistage member and find EOS to be extremely complimentary with Vistage’s focus on best practices within every area of a company and it’s leaders. We gain value from both of these investments and I would encourage others to explore working with Ed and evaluating the power of adopting EOS as their one operating system.”
Lori Gordon, CEO, MandMarblestone, LLC
“Approximately two years ago I realized to grow my business I needed to work on our company’s infrastructure because I literally had no more time or energy. I started networking to find solutions and ran across Ed and EOS. After speaking with Ed and reading TRACTION I quickly understood EOS could add a pivotal piece to my company’s infrastructure, and could give me precious time back to enjoy my family & life.
I consciously held our company back from growing for the past three years. After almost two years operating Rehab1 under the principles of EOS I now understand what Gino Wickman and Ed Callahan both state: ‘Be careful what you wish for, because EOS can get you there.’ I fully agree with this statement and look forward to the future growth of our company. With the necessary systems and processes in place we are now ready to grow once again. Now our future growth will be manageable, reproducible, and I’ll consistently have a pulse on all aspects of my business.”
Brian Hall, Owner, President, Rehab1, LLC
“Ed has done a terrific job working with our team to implement the EOS process. We are a high growth enterprise software company increasing our headcount by 5 times over the past several years. With all this growth we were looking for a management system that would give our team a single language and would be indicative of the entrepreneurial spirit of the company.
EOS has been that system for us and has met and exceeded our expectations helping our team stay focused on solving the most pressing issues that enable us to continue to execute on our plans. Ed has been very effective in helping our team understand the process and how they can roll this out to the rest of our organization.”
Ned Moore, Chairman, CEO, Founder, Portico Systems, Inc.
“Over the years DVL has become very skilled in many core business competencies, including Sales Management, Accounting, Human Resources, Finance and Information Technology. However, it became clear to me we needed a better way to get our management team on the same page with regard to strategic planning so as to continue to move the company forward.
At that time Ed presented the EOS program to our team, and the team agreed to enter into the program by a narrow margin. One and one half years into the process, everyone on our team would testify to its success. We are all in synch with each other, as is the rest of the company.
Ed and EOS have made a tremendous difference in both the present and future of DVL. I would highly recommend anyone with the same concerns meet with Ed to learn more about both he and the EOS program.
Michael Murphy, CEO, DVL, Inc.
“I can’t express how valuable the EOS Program has been to Lippolis Electric, Inc. The EOS philosophy and methods have made a big difference in how we do business and even in how I conduct myself overall.
Everything from Rocks to developing our Core Values has been an eye opener for me. Everything that we have implemented has made a difference and I’m very proud of that. It is because of Ed and EOS that we were able to solve some of our issues forever.”
Carmine Lippolis, Owner, Lippolis Electric, Inc.

“Ed and I started on the same day at IBRIX. We worked quite well together as we share the same business style and approach to problem solving. Ed . . .is very methodical in his approach to engaging with customers. He understands what needs to get done from day 1 of the engagement to the closing of the deal. I would work with Ed again in the future”

“I worked for Ed during his entire tenure at Neoware, and found him to be a very capable CEO. He understood the software and hardware development process, but was comfortable delegating and never micro-managed. Ed navigated Neoware through an extremely difficult period where ASP’s dropped in half due to competition from low-cost PC’s. I’ve stayed in touch with Ed as he has continued his career.”
Ed Parks, VP Woldwide Engineering, Neoware, Inc.

Pat Dunne, General Manager, Europe, Neoware, Inc.
