William Mulholland worked with The Elizabeth Ministry from the inception of our work in 2006 until 2014.  His counsel and skills focused on ensuring our accountability and credibility to our funders through our audit process, which also included our accounting policies and procedures. He was an invaluable asset to the foundation of our organization.

Bill Mulholland has been my accountant for many years. He  has always provided impeccable, thorough  reports/tax returns in a timely, patient fashion.  He has explained the data in a clear, understandable way and has provided sound advice and insight re: sensitive issues.  I highly recommend him.

I met Bill when he was part of a forensic accounting team reviewing the activities of a non-profit organization that was going through a difficult leadership transition, where I too was consulting.  I was so impressed with Bill’s professionalism and demeanor that when I was asked to serve as the organization’s Chief Operating Officer, I immediately sought Bill out to bridge the gap until we could find a full time office/accounting manager.  Again, Bill stepped in and not only put new systems in place but also assisted with the search for a permanent hire.  I have continued to reach out to Bill when CPA services were needed and have recommended him to several other similar organizations when the opportunities have arisen.

As a small business owner in Georgetown, D.C. since 1964 I have the pleasure of my association with William Mulholland since 2008.  Bill is an excellent accountant for any small business or individual who would require tax work, profit and loss statements and audits.  I am always able to contact Bill when I need assistance and find him very reliable, informative and friendly. I am very happy and honored to recommend Bill anyone seeking professional accounting services.

Bill Mulholland is reliable.  For me, he was always there when I needed him.  He always responded quickly to emails, phone calls and text messages. If I needed him to attend a meeting, even in the evenings, he always did so without question.

When tax time rolls around each year I feel a great sense of comfort knowing that Bill is in my corner to prepare and file our federal and state returns.  We depend on his skill, knowledge and attention to detail and enjoy his helpful, friendly manner.  Our filings have always been orderly, complete and acceptable to IRS.  Bill’s fees are exceptionally reasonable.  I have recommended Bill to many of our friends and will continue to do so with great enthusiasm.

I didn’t think I needed an accountant, until I realized how invaluable it’s been having Bill as our accountant.  I needed someone that was an expert in knowing current tax law and all things accounting. An ordinary accountant will process your taxes accordingly and you may or may not get a refund, but an excellent one takes the time and extra step to understand your financial circumstances and ensure you reap the benefits and understand the drawbacks too, to owning your own business – and that’s where Bill has shown his worth. When it comes to filing taxes Bill has been a real asset to me and my husband. He is extremely trustworthy and has a ton of experience, and I’d recommend him to my family and friends in a heartbeat.

I worked with Bill at So Others Might Eat, a 501(c)(3) organization located in DC, that serves the needs of the poor.  I found Bill to be very competent, have a strong work ethic and be an excellent problem solver.  I believe he excels in situations where  finance departments need a fresh set of eyes to come in and set up policies and procedures and prepare for audits.
