Meet The Founder

Rosemary Linden

President | 2025 CFO of the Year

Most business owners excel at what they do, but struggle to turn financial complexity into strategy. That’s why I founded Momentum CFO — to help leaders like you gain the clarity, tools, and momentum you need to scale with confidence. Through fractional CFO and Financial Planning & Analysis (FP&A) consulting services, I turn your numbers into a roadmap for smarter growth.

With over 25 years of financial leadership experience, I’ve led FP&A teams at global corporations like Quest Diagnostics and WD-40 Company and managed P&Ls exceeding $1 billion. I know how to adapt enterprise-level best practices to improve the performance of smaller, growing businesses. Since launching Momentum CFO in 2016, I’ve worked with clients nationwide to strengthen cash flow, increase profitability, refine pricing, build strategic budgets and forecasts, and prepare financial materials for boards, investors, and lenders. Whether you’re preparing for growth, navigating an acquisition, or simply trying to make sense of the numbers, I’ll help you shift from reactive decisions to confident, data-driven leadership.

I’m honored to contribute to the finance profession and my community. I serve on the FP&A Advisory Council for the Association for Financial Professionals, where I help shape global standards for FP&A, and I’m part of the leadership team of San Diego Women in Finance, advancing the development of women leaders in the industry. The San Diego Business Journal has also recognized my work, The San Diego Business Journal recognized my work as 2025 CFO of the Year in the Consulting CFO category, after also naming me a Leader of Influence in Accounting & Finance and a CFO of the Year Finalist in 2023 and 2024.

I earned my BA in Economics from the College of William & Mary and an MSBA in Financial and Tax Planning from San Diego State University. Outside of work, I love to balance spreadsheets with a little adventure — scuba diving with my husband, tackling LEGO builds and puzzles, practicing pliés in ballet class, and relaxing at home with our two mischievous kitties.

What Our Clients Say

Rosemary and her team possess deep knowledge in numerous areas like financial reporting, business intelligence, and data analytics. Momentum CFO will help your organization gain better insights and offer strategic recommendations to achieve your goals.

I would give Rosemary ten stars on a five star scale if I could. I am happy to refer anybody that I know to Rosemary’s work because of the high trust that I have in her and integrity of her work.

I brought Rosemary in to help my business when it was in a financial crisis. She immediately helped me right my ship by pinpointing vendors that were charging too much or failing to deliver. Rosemary evaluated my company’s financial situation, found issues that could lead to future problems, and created a plan to generate greater profit with less effort. Now my company is forward-thinking, and I know my finances are in good hands with Momentum 

I gained invaluable insight from Rosemary’s financial reports and dashboards! They helped me make important executive decisions that increased our business’s revenue and profitability.

Rosemary is diligent, committed to high quality work, well versed in financial practices, and able to communicate complex information to any audience regardless of its level of understanding of financial statements.

Rosemary has gone above and beyond since the very start. She is incredibly respectful, systematic, detail oriented, and exceptional in every way. It is extremely reassuring to have her guidance on present and future financial health.

Rosemary’s spreadsheets are beautiful, in the sense that they are laid out very methodically and built with easy to read color coded cells in such a way that when you punch in numbers, you know where to look for answers. In addition, her advanced Excel skills and business acumen, which comes from working in various industries and companies of very different sizes, really helped me, the client, because she can get to the heart of the issue very efficiently and not waste time and money.

I must admit that I had no idea of the tremendous value a CFO could bring to my company until I hired Rosemary. Rosemary has been fantastic to work with over the past two years, and I have learned so much about financial metrics and reporting from her. Not only does Rosemary deeply analyze and report on every aspect of our business, she constantly provides suggestions on how to streamline and improve the financial health of the company.

Our business had recently completed an overhauling of how we did things; we found things that had been done for years and needed addressing. We wish we had known what Momentum CFO could have done for us sooner, so we could’ve saved time and money. Having Momentum CFO on board has changed everything: our accounting, reporting, forecasting and most of all budgeting improvements. We recommend all types of businesses take the time to experience what we now have!

My experience with Rosemary has been nothing short of insightful and meaningful. It has been a learning and development partnership between us. She has a wealth of knowledge that aids in my role at Cal Head & Neck. She is a great partner and collaborator and I am grateful to have her as a colleague.

Rosemary’s professionalism and attention to detail always impressed me. Her extreme attention to detail, building very complex financial models, and “teaching you to fish” approach is really incomparable.

From our initial meeting, Rosemary was not trying to push services. She took the time to understand our company to design a plan to meet our goals. Her commitment is what’s best for us as clients. Rosemary’s qualities are not seen very often in business. I want to thank you for your integrity, honesty, and professionalism.

It’s time to unlock your business’s financial potential.

Make your numbers work as hard as you do.
