I've been very pleased with the accounting and bookkeeping services provided by Lee, Mongelli & Associates. Their team is always responsive and quick to address any questions or concerns I have. They are meticulous in their work, ensuring accurate and thorough financial records. They even noticed and addressed some potential issues with my finances that I hadn't even realized. Additionally, they were proactive in reaching out to request any missing documents or information needed to complete my tax returns. The entire team is professional, knowledgeable, and easy to work with. I highly recommend their services to anyone in need of accounting and bookkeeping assistance.

In the many years I have used the services of Lee, Mongelli and Associates, there has never been an unpleasant experience. The staff and owners are always helpful and knowledgeable. B. Lee and G. Mongelli have done my business and personal taxes for over a decade with no issues or problems and have been there with me and for me in an IRS audit, successfully and professionally handling my case. Lee, Mongelli and Associates, in the knowledge and attention to the details of my returns, has saved me considerable tax dollars, finding deductible items I would never have known about. Most years the reduction in my taxes was greater than the cost of their services. Employing the services of Lee Mongelli and Associates is absolutely recommended.

Lee, Mongelli & Associates have been preparing our personal and business tax returns for years. We have great confidence in their work and our returns are prepared accurately, delivered timely and at a fair price. The client portal is super easy to use for transmitting documents back and forth!
Gary (Mongelli) offered trustworthy advise (and some hand holding) as he helped me through the navigation process of my late mother's estate with taxes and inheritance. I really appreciated his insight and candor.
Staff and members of the CPA team are always available to assist me when I call, whether for a simple bookkeeping question or more complex tax planning situations.
I like this firm and I think you will too!
It is my pleasure to recommend Lee, Mongelli & Associates.

We really enjoy the help this company gives in guiding us through our first years as a business. It's nice having a personal contact (almost) hold our hands through the small business taxes.

And in response to someone saying they are bribing for 5 star reviews... Your review seems like it deserves 5 stars but you whine like a child for not getting a discount. Read my Laws Grill review... They offered free food for me to change it.... I didn't because I give HONEST reviews...

As new clients to Lee, Mongelli & Assocaites, so far, we have had a great experience. They took the time to walk us through the process and personally met with us to chat through our tax needs with businesses and personal taxes.

Their professionalism and expertise have already made a big impression, and we are looking forward to working with them long-term. Highly recommend!
