We are grateful, and this is just the beginning. Our goal is to grow to a level where we can impact the way the IRS interacts with taxpayers on a national scale. Our mission is to continue practicing law with passion and compassion, educating and advocating for our tax and business clients so they can sleep at night.”
About the 2026 Inc. 5000
This year’s Inc. 5000 recognizes a new class of companies redefining what growth looks like.

About the Law Office of Pietro Canestrelli, APC
Founded in 2016, the Law Office of Pietro Canestrelli, a Tax Controversy Boutique, APC (“LOPC”) was built on a simple belief: people facing tax problems deserve more than technical answers. They deserve to be seen, respected, and supported as human beings. That belief is deeply personal to founder Pietro E. Canestrelli, whose perspective on tax law changed permanently after watching his own brother struggle with tax problems during an already difficult time. The experience reinforced for Pietro that tax issues rarely exist in isolation; they often arrive alongside financial pressure, family challenges, business uncertainty, health challenges, and personal loss.
LOPC was created to provide sophisticated tax representation while helping clients move from fear and confusion toward clarity, control, and peace of mind. The firm meets clients where they are by combining attorney-led tax guidance with a highly personal client experience: a dedicated legal team, clear communication, and access to real people who understand their journey. The firm represents individuals and businesses in serious federal and state tax matters, including tax controversies, audits, and collections, expert tax opinions, and proactive tax planning.
That same philosophy shapes how LOPC builds its team. The firm hires not only for skill and experience, but for alignment with its PEACE values: Passion, Education, Advocacy, Compassion, Every Time. Pietro brings 27 years of tax-law experience to the firm. Before entering private practice, he served as an attorney with the IRS Office of Chief Counsel in Washington, D.C., and he holds an LL.M. in Taxation along with specialized credentials in tax law and tax planning. Today, LOPC continues to grow with the goal of reaching more taxpayers without losing the personal, compassionate experience on which the firm was founded.
