Meet Diana


Diana’s fierce determination to finish what she starts, paired with her responsive nature, ensures that her clients receive reliable and timely solutions for the dynamic business challenges they face.

As a long standing member of our audit and attestation team, Diana has gained a wide breadth of experience performing and managing financial statement audits. She is the industry leader for not-for-profit, benefit plan, professional service, and technology companies, and has an in-depth working knowledge of the undercurrents of each industry. 

When she’s not in the office taking care of business, Diana enjoys traveling and reading. In fact, she is an active participant in Mowery & Schoenfeld’s Ladies Only Book Club.

What is most rewarding about being an accountant?

Every day is different than the day before so it is never boring. You may be working with the same clients each year but their accounting needs constantly change with their business.

What is your philosophy as it relates to your job?

To be everything I want to be instead of failing at everything I should be.
