Tristan Pettigrew , CPA

Assurance Manager

It was my friend who initially convinced me to take a business class in high school. I didn’t think that I would enjoy it, but I was pleasantly surprised to discover that this class would ignite my passion for accounting. Several years later, I had the opportunity to get hands-on experience in the accounting profession thanks to my university’s co-op program, including an eight-month work term at Hendry Warren. It was then that I truly knew that accounting was the career path for me.

Today, I take on a variety of projects at the Firm in my role as assurance manager. I assist our clients with their reporting needs whether it be compilation, review or audit financial statement engagements as well as their tax reporting requirements for both for-profit organizations and NPOs. Additionally, I enjoy serving as a mentor for the Firm’s co-op students and junior staff, helping them solidify their passion for the profession, just as my mentors did for me. To further develop my skills and knowledge in the field, I completed a Certified Fraud Examiner designation in 2022.

Tristan joined Hendry Warren as a co-op student in 2020 and graduated from the University of Ottawa with an Honours Bachelor of Commerce in Accounting later that year. In 2021, he started as a full-time staff member at the firm. He is a member of CPA Canada and CPA Ontario and obtained his Chartered Professional Accountant Designation in 2023

Testimonial from Rob Waterman - President at Waterman Sales Ltd.

We have been in Business since 1992 and had an accountant who was a family friend. When he retired, we needed to find a new accountant. Jacob at Hendry Warren was recommended to us through our Lawyer. We met with him and were impressed immediately; over the years we have gotten to know more of the staff and are equally impressed. They have done our company taxes, company valuations, share purchases, tax planning, covid relief, personal taxes, etc. All of which have gone very smoothly. Hendry Warren is aware of new legislation and has helped us grow as a company.

Testimonial from Colin Goodfellow - field_5cebff5066bfc

I have used Marie Fraser and her team at Hendry Warren for business, personal and special projects. Deep enough bench strength to cover anything, and small enough to pay attention.
