about our firm

Sturos CPA is a full-service accounting firm located in Michigan’s Upper Peninsula. We offer professional CPA services including consulting, tax planning, auditing, payroll reporting, accounting, bookkeeping, and more. 

Sturos CPA was founded in 2004 by Paul Sturos. Paul wanted to bring his great quality of work directly to his clients after working with the firm of John I. Jukuri for over 20 years. John I Jukuri was a premier firm in the area and was based off the founder’s experience at the international firm Ernst and Whinney (now Ernst & Young).

Paul has since built a full-service CPA firm adding staff and services offerings along the way. Paul R. Sturos CPA was renamed Sturos CPA, P.C. in 2017 as a commitment to the future of the firm and his son Nathan joining the firm. With Paul and Nathan as partners, the firm is poised for the next generation of growth and commitment to its clients.

We are passionate about helping business owners build their business. We want to work with growing, thriving businesses.

Sturos CPA has a keen sense for technology, manufacturing, construction, and service businesses. We enjoy working with people that are pushing the envelope of science and business.

We like the challenge of the complex, intricacies of high-level finance, and the tangible feeling of putting a product into the market.

Sturos CPA assists individuals and businesses in making decisions based on data, not on gut-feelings. We take great pride in the quality of our work. We will do what it takes to get something done and get it done right. Our firm quality control system provides detailed levels of review on all work products before they go out the door.

Our team constantly delivers accurate work and values long-term relationships with clients. We know that confidentiality is key in our tight-knit community – we wouldn’t be here 40 years later without it. Our professional team and vast experience allows us to provide top-notch CPA solutions to businesses.
