Welcome to
Whisman Giordano

CPA and business consulting firm

Way back when bell bottoms and 8-tracks were all the rage, our journey to become one of the most respected public accounting firms in Delaware and the surrounding region began.

Then, as today, we provide unparalleled accounting, auditing, bookkeeping, tax, and business advisory services while maintaining a singular focus on the relationships we develop with our clients, referral sources, and the community. Our commitment to Building Extraordinary Relationships stems from wanting our clients to succeed. We do this through the latest technical expertise, efficiency, responsiveness, respect, and caring.

Building extraordinary
relationships since


We’ve chosen to celebrate our 50th Anniversary with our 50 Acts of Kindness initiative. It’s the connections made with clients, the community, and our team that makes the Whisman Giordano experience truly unique.

Superstars in Business Recipient for 2020

As we are recognized with the Superstars in Business award from the Delaware State Chamber of Commerce,
we would like to say a special “thank you” to the entire Whisman Giordano team
for making this recognition possible.

From the moment we engaged Whisman Giordano, it was clear that we made the right decision. Our small business approach to navigating complex financial and tax strategies immediately improved while we successfully navigated a significant expansion to our business operations. During our firm’s growth over the last several years, Whisman Giordano’s professional support and strategic guidance evolved alongside us, allowing us the opportunity to evaluate potential opportunities and swiftly develop effective solutions for an ever-changing financial environment.

Our successful teamwork starts and ends with our dedicated point of contact, the invaluable Ed Devenny. Together with Joe Giordano, Ed is the definition of professional excellence in accounting. Ed consistently demonstrates a deep understanding of complex compliance scenarios while providing plain-language, straightforward recommendations to us that explain the advantages and, more importantly, any disadvantages of various strategies. Simply put, Whisman Giordano has successfully understood and improved our business like it was their own, and we can’t thank Ed and Joe enough for their invaluable contributions, insight, and guidance. Congratulations to Whisman Giordano on 50+ years of outstanding client service!

Whisman Giordano has been CHEER’s auditor for the past 5 years. They continue to prepare all of our tax filings and have guided us through a federally mandated consolidation of financial statements from a separate subsidiary. Through the year’s they have assisted with the orientation and training of new finance staff. Their entire team has always been timely and responsive to any of our needs and their senior members are always available. Whisman, Giordano is a great resource and asset to our organization.

Goodwill of Delaware & Delaware County has worked with Whisman Giordano for numerous years. In conducting our annual audit we have found every step in the process from on-site field work through final Board presentation to be professional, addressed with a sense of urgency, thorough and accurate. Both our staff and board have developed strong working relationships with Whisman Giordano that focus on maintaining a strong financial position to support the mission of Goodwill.

- Colleen Morrone, President & CEO of Goodwill of Delaware and Delaware County

We have used Whisman Giordano since 2012 for a variety of tax and audit services. They took the time to understand our unique business and its challenges. All deliverables are received on or ahead of schedule and they help me meet several of our more stringent deadlines. As a local firm, the staff is always available when needed. They will stop by the office, answer questions and go the extra mile to make sure my needs are met. On top of professionalism, the staff at Whisman Giordano are just good people you can trust.

- John Charette, CFO of XO Energy, LLC

I'd like to take a moment to recommend Joe Giordano's work as an Auditor and a Director at Whisman Giordano and Associates. I have worked with Joe for about 12 years and his firm over 16 years. We are a small non-profit who needs to rely on the expertise and professionalism of the firms we contract with. Joe has brought much-needed help and advice. We are very comfortable with him being in charge of our audits. We are able to have contact with him all year not just audit time.

- Donna Goodman, VP & CFO at Westside Family Healthcare

I have known Joe for close to 10 years and have been a client of his and Whisman Giordano's for the past 5 years. I have nothing but positive feelings to say relative to Joe's attentiveness and professionalism. He makes me feel like I'm his most important client anytime I contact him and the firm has been very cost-efficient and professional in overseeing the tax preparation for my 6 different business entities. There is a fair amount of overlap among the businesses and WG has helped us through those complexities. Joe and his Father and Alex are a pleasure to work with.

- Eric Holloway, Owner-Signature Group of Companies

I have had the pleasure of working with Joe Jr. and his team at WGA in multiple capacities and cannot say enough wonderful things about their style and the way they operate. Whether it was as a client for their own HR and handbook needs, or working together for a mutual client's needs, Joe and his team were always incredibly responsive, realistic, and listened to any HR recommendations proposed. We have become great partners in delivering quality business consulting to local small and growing organizations. They proactively communicate and truly understand how finance and HR go hand-in-hand to run a successful small business. I'd recommend their services, and enjoy working with them in any capacity. And most of all, who else makes finance, accounting and taxes fun?!

- Maria Clyde, PHR, SHRM-SCP - Director of HR at B+H Insurance

I really feel like you pay attention to our needs. I know I’m one of many, but you did a great job making me feel the only one. I am sure all your clients feel the same way.

- CEO, pharmaceutical company

Lisa has been my accountant for a number of years. I look forward to our meetings, not just because she is a terrific accountant, and always answers my questions clearly and kindly, but also because Lisa is a pleasure to work with, and through our business relationship she’s become a friend. Lisa looks out for me and my business, helps me address issues proactively, and identifies opportunities to strengthen my business. I highly recommend Lisa to help any business, small or large, achieve their financial and accounting objectives. WG&A is a true family business and they make me feel like part of their family, too.

- Alisa Morkides, Owner of Brew Ha Ha! and Brandywine Coffee Roasters

We have been working with Dennis Perdue and his team at Whisman Giordano for a little over three years. They not only provided us with excellent corporate financial advice & accounting services but personal as well. The staff is always very professional and efficient. We would highly recommend Whisman Giordano for anyone looking for excellent accounting services.
