Peer Review.

The Concierge Consulting & Accounting, PLLC team is pleased to announce the successful completion of our independent peer review of our accounting and auditing practice. CCA received a pass rating, the highest rating available. Firms can receive a rating of pass, pass with deficiency (ies) or fail. Thank you Marcia J Hein, CPA for conducting our peer review and providing us with valuable insights. We are formally evaluated every three years but internally we review our quality controls every year. Peer reviews allow us to continue to improve upon our client services to serve you better.
You may be asking yourself, what is a peer review? The American Institute of Certified Public Accountants (AICPA) requires its member firms to undergo a peer review every three years. A peer review is a periodic external review of a firm’s systems, engagements, quality control, internal controls, and adherence to professional standards in accounting and auditing and is also known as the AICPA’s practice monitoring programs. The purpose of a peer review is to promote quality in the accounting and auditing services provided by CPA firms. Peer reviews ensure that CPA firms are preforming at a high standard which allows us to better serve the public interest


I have known Theresa for many years and her work ethic, attention to detail, and overall knowledge base are outstanding. If you are looking for help with tax and accounting I highly recommend and endorse Theresa.

Business Wealth Advisor

Wonderful, professional CPA and consultant. I met with Theresa and she was a pleasure to deal with. She explained my tax situation in a very understandable way. She presented a clear plan and strategy. She honored her timeline and budget and walked me through all the steps in the process. She even reviewed my current tax return and pointed out deductions and credits that had been missed. She is highly knowledgeable and such a difference from other “tax professionals”. She truly cares about her clients and giving them the best service possible. I would highly recommend her to all my family and friends.

Satisfied Client

Theresa is an incredibly talented individual with so much drive and ambition. She puts her clients best interest as her top priority and goes above and beyond what is expected. She is one of the most diligent and hardworking individuals that I’ve ever met. She has become a role model for me and someone I deeply respect. Working with Theresa has not only been educational, fun, rewarding and professional, but it’s also been incredibly rewarding.

Future Entrepreneur

Theresa is a pleasure to work with. She is smart, well versed in her craft, and has provided unique assistance in helping our clients with their tax and accounting needs. I strongly urge those to wish to be pro-active tax planning to engage her help.

Financial Advisor

Theresa is not your typical “bean counter”. I was so impressed with her knowledge, and her ability to put her clients at ease, that I left my accountant of over 10 years to place my personal and business accounting with her. Even at the height of the busy season, she finds time to properly service her clients and always does so with a smile. I refer my clients and friends to her without hesitation.

Happy Client

My return is a work of art! You did an amazing job! You perfectly used every dollar of non-refundable credits and stopped at the refundable ones! Great job.

A Very Happy New Client

Words To The Wise.
