Rick Mull helps business owners turn financial confusion into clear strategy, stronger margins, and sustainable growth. As a leader at CFO Central, he works directly with companies that need executive-level financial and operational leadership—but don’t yet need a full-time CFO, COO, or revenue strategist.

Rick’s career has been built on a simple belief: businesses rarely fail because of lack of effort — they struggle because they lack the right financial visibility, operational discipline, and decision framework at the leadership level. His work focuses on installing those systems so owners can move from reactive problem-solving to confident, data-driven growth.

Over the years, Rick has partnered with companies across construction, manufacturing, service, and growth-stage businesses, helping them improve cash flow, strengthen lender relationships, increase enterprise value, and build scalable operations. His approach blends financial leadership with practical operational execution, ensuring strategy actually gets implemented — not just discussed.

Rick is also the author of the 2003 business book Are You Selling to Potential? and is currently authoring an updated release titled Nobody Buys Potential, expanding his long-standing focus on how companies communicate value, improve positioning, and drive measurable performance.

Today, Rick works closely with business owners and leadership teams to:

• Improve operational margins
• Create reliable financial forecasting and cash control
• Prepare companies for financing, transition, or growth
• Install accountability and performance management systems
• Provide fractional CFO / COO / CRO leadership

His mission is straightforward: help business owners replace uncertainty with clarity — and turn good businesses into highly valuable ones
