Thomas A. Petrella, CPA

A lifelong Rochesterian, Thomas grew up in Irondequoit and attended St. John Fisher College where he graduated with a Bachelor of Science in Accounting. The career choice for Tom was easy…follow in the footsteps of his father John S. Petrella CPA who began his practice nearly 50 years ago. Soon after Tom joined with his father, Petrella & Petrella LLP was formed. For the next 25 years, Petrella & Petrella continued to grow and flourish.

John’s retirement created the opportunity for Tom to form a new partnership. In the fall of 2012, Petrella Phillips LLP was formed. The combined resources and specialty practice areas will allow us to provide even more services to our clients.

Tom will continue to focus on clients in the medical sector as well with the firms’ corporate and individual clients and will continue to offer interim and permanent CFO and controller services.

Michael M. Phillips, CPA

Michael is also a lifelong Rochesterian and has lived in Brighton his entire life. From early he knew he wanted to be CPA. An internship at a (then) Big Eight CPA firm affirmed his desire to be CPA. In 1986, he graduated from St. John Fisher College with a Bachelor of Science in Accounting. Michael started his professional career working in the office of an independent CPA before moving on to a regional Rochester based CPA firm. In 1998, he decided it was time to open his own CPA office in Henrietta.

While at St. John Fisher, he cemented a friendship with Thomas Petrella, with whom he is now partnered.

Michael will continue to focus on clients in the real estate sector as well as with dentists, start-ups, and those clients with complex Federal and State tax resolution issues.
