The leadership team
Meet our mentors and matchmakers, coaches and collaborators, corporate veterans and finance whizzes. An adaptable and friendly group, the senior leaders at RoseRyan wear a variety of hats to hire the best, inspire our gurus and keep our clients happy. Kathy and the rest of the leadership team have the broad, deep experience (from years at the Big 4, Fortune 100 companies, as well as many startups) that clients really trust.
Kathleen Ryan, CEO & CFO
Kathy started RoseRyan on a mission to let highly savvy finance pros combine challenging assignments with a flexible work/life balance-- and the firm has grown beyond her wildest dreams.
Kathy was director of finance at Quantum and tax manager at Price Waterhouse before co-founding RoseRyan in 1993 with Sue Macias. In addition to management expertise, her skills include general and cost accounting; tax and SEC reporting; forecasting, budgeting and planning; business finance; and systems planning and implementation. She has served as CFO for over 50 emerging growth companies.
Her leadership has been widely recognized. In 2015, the San Francisco Business Times named Kathy as an influential woman in Bay Area business. She made Accounting Today‘s national listing of the sector’s top 10 leaders, known as the Managing Partner Elite. And in 2012, the San Jose/Silicon Valley Business Journal named her one of the most influential women in Silicon Valley. Formerly a Big Four CPA, Kathy holds a BS in accounting from Santa Clara University. She serves on the finance committee at St. Michael’s Church in Livermore. Kathy loves golf, needlepoint and (her guilty pleasure) romance novels.
Maureen Ryan, Vice President
Maureen joined RoseRyan in 2000 to spearhead business development. Before that, she was an account executive with Nortel Networks, marketing manager at Bay Networks and sales operations manager at Quantum Corp. As engineering program manager at General Dynamics, she was responsible for landing a $20 million government contract for the development of a major missile system.
Maureen holds a BS in aeronautics from San Jose State University and an MBA from San Diego State University. Her passion is the relentless pursuit of equal rights for women.
Pat Voll, Vice President
Pat provides strategic guidance into several practice areas at RoseRyan, including corporate governance, strategic projects and operational accounting. In addition, she manages multiple client relationships, develops new solutions for the firm, oversees strategic and corporate culture programs, and provides thought leadership on corporate governance and transaction topics in the press and media.
Pat has worked in various financial management roles with primarily mid-size, public, technology companies as CFO, vice president of finance and controller. She also worked with Price Waterhouse for five years as an auditor.
Pat does a lot of things well, including revenue recognition, SEC and management reporting, mergers and acquisitions, SOX compliance and risk management, and plain old nuts-and-bolts accounting, to name a few. Pat is a former Big 4 CPA, CGMA and holds a BS in accounting from San Jose State University.

Before joining RoseRyan in 2012, Stephen spent 13 years as a CFO of NASDAQ-listed companies, and 8 years in auditing, including several as a manager with Price Waterhouse (now PwC).
Stephen is a chartered accountant (England and Wales) and has a diploma in accounting studies from Oxford Brookes University, England.

Chris has a BA in marketing from Creighton University. He is an active youth soccer and basketball coach (as if Silicon Valley high tech wasn’t already heart-pumping enough).
Missy Manriquez, Talent Manager
Missy holds the Talent roles of Scheduler, Recruiter, and Head of Learning & Development. As the Scheduler, she is responsible for the complex task of scheduling consultants for client engagements. It’s an intricate matching process of technical skills, soft skills and cultural fit to meet our clients’ precise requests for each assignment. She also focuses on recruiting senior level finance and accounting individuals to the firm.

He is a published authority on the physics and biomechanics of baseball and writes and speaks on this topic at sabermetric conventions. Needless to say, he’s a fan of Moneyball, Billy Beane, and the Athletics. An avid physical trainer, he hosts friends for weekend Crossfit-style workouts, practices Kung Fu combatives at the local Shaolin temple school, and leads the RoseRyan kettlebells classes to keep his teammates in shape.

Prior to that, she worked three years at Sun Microsystems, with roles in strategy and global programs, and before that nine years at Apple in the USA sales and marketing group. She earned her MBA in finance from the Wharton School at the University of Pennsylvania, where she also earned a MA in International Studies.
