About Diane
Cutting through the noise to get things done.
My clients come to me with a problem to solve, a business to grow, or a transition to navigate. I help them find the issue that matters, build a practical solution, and then carry it through to results.
Where I've been
I spent 30+ years at Omnicom Group, helping to grow it into a multi-billion-dollar global advertising and media organization. Over that time, I have held various senior leadership level roles in Finance, Operations and Procurement.
I started my career in Public Accounting as a CPA and auditor and built a foundation in financial controls and compliance. From there I moved into financial reporting, acquisition due diligence and integration, and eventually enterprise leadership.
Along the way I:
- Owned financial and operational oversight of more than $1 billion in annual third-party spend across technology, data and analytics, AI, production, real estate, professional services, and more. Managed a global team of category experts and led negotiations of thousands of complex vendor and strategic partner contracts to drive margin improvement.
- Partnered with executive leadership on transformation initiatives, including financial platform modernization, real estate optimization, and AI adoption.
- Managed consolidated financial reporting for SEC filings, executive board presentations and regulatory compliance during a period of significant organizational growth and complexity.
I've seen business from every side of the table: as the operator, the finance partner, the negotiator, and the person accountable for the outcome.
That perspective lets me know quickly what to evaluate and where the real value is.
Beyond the work
I hold a B.S. in Accounting, magna cum laude, from Villanova University, which is also where I met my husband, John. We love living in Ridgefield, Connecticut, where we raised our three amazing children and learned how to manage life's priorities, juggle competing demands, and keep a sense of humor.
