Profile bio

About Ed Callahan

As an Emeritus EOS Implementer™ (business coach) I collaborate with private business owners and their leadership teams teaching them how to get more of what they want from their business. I help small business owners implement a business management system called EOS®, the Entrepreneurial Operating System®, which enables them to harness all the moving parts of their business and focus all their energy and resources in one meaningful direction. EOS® makes leaders better at execution by becoming a cohesive team.I love being an EOS® Implementer. It combines my personal passion for teaching, facilitating, & coaching with my business career, including being the President of two small, public businesses. I have walked in your shoes.Companies implementing EOS® come from any industry and typically employ between 10 to 250 employees. Some smaller, some larger. If you have people, EOS can help. What you do is immaterial. You are the experts in your business, not me.I work primarily with companies located within about an hour's drive around Greater Philadelphia. I have a diverse set of EOS® clients, including a franchise owner, a specialty chemicals company, a pharmaceutical analytics company, a software company, a water treatment company, several mechanical construction companies, and a search firm - to name a few. If you are an owner/CEO who is frustrated with the progress of your business and you are open to change, we should talk. I invite you and your leadership team to my session room in King of Prussia, PA for a complimentary 90 minute meeting to get to know each other and to explain how EOS works and how we might work together.I can be reached at 484-432-9388 and edcallahan@coherent-coaching.com

Listed skills include Leadership, Entrepreneurship, Executive Management, Training, and 24 others.
