It is with great pleasure that I write the following review for David Reinus CPA, Inc, and specifically for owner Mr. David Reinus, CPA and his associate, Megan Bell, CPA. I own a mid-sized law firm in Thousand Oaks, California, and currently employ 50 people, 80 people pre-pandemic. My firm hired David Reinus CPA, Inc, in December 2019 and it was the best decision I ever made. Little did any of us know what was coming the 1st quarter of 2020. Like many business owners, I thought the COVID 19 Pandemic would be the end of my law firm. I was forced to furlough approximately 70 of my 79 employees

I've been working with David right from the start of reviewing a potential business purchase, right through to the quarterly reports, tax filings, and payroll. He answers questions quickly and throughly. Megan handles the payroll works seamlessly. Probably not the least expensive CPA out there, but you get what you pay for!

We’ve been using David and his team for three years now and I couldnt ask for anything more in an accountant. Response time whether via email or call is impeccable and their overall knowledge is second to none. Highly recommended.

My father, a very successful business man, told me the key to success as a business owner is, have a great lawyer, a great insurance rep, and a great accountant. David Reinus has been the foundation of this triad for many years. We trust him implicitly and his clear communication, professionalism and concern for our well being are an essential and much appreciated asset to our company.

I have worked with David and Megan going on 5 years now and I am very pleased with the level of service that we receive. My wife has an S-Corp and there are many forms that David takes the time to explain to us with great patience. My biggest requirement is response time. David always responds in a timely manner and when I need his help he is always there! Thanks David and Megan!

I am very pleased with David and Megan's accounting services; in fact, they're more like an extension of my business. David gets back to my questions as quickly as I pose them, and Megan's reply time is also nearly instantaneous. David offers a blend of wisdom and professional accounting services. I never feel alone in the financial side of my business, and am grateful to have retained his firm for my accounting needs.

As a small business owner, I count of David's sage advice to make sure that I am making sound business and tax planning decisions. His experience, patience and responsiveness are so helpful and greatly appreciated. I wouldn't want to operate without the resources that he and Megan bring to my business. In regards to Megan, her focus on our expenses and understanding of my spending has saved me hundreds of dollars by finding charges that were fraudulent and reaching out to help me figure them out. I simply cannot provide a stronger recommendation for anyone needing an ethical CPA as a partner in

David is extremely competent, reliable, and ethical. We are a medium-sized
business that previously worked with a big accounting firm that assigned us
to their new staff every quarter. Our bills were high but they didn't have
a clue about our business. We did some homework and found David, and he has
been our CPA since 2008. There is something to be said about being able to
sleep at night knowing that David is handling our business accounting and
taxes and getting them done correctly. I would highly recommend David
Reinus, CPA.
