Staff Profiles

Mark Linzmeier, CPA and Owner

Mark Linzmeier is a Certified Public Accountant (CPA). He purchased the customer base of Stodola Accounting and Tax Services and established Professional Tax & Accounting Services (PTAS). Mark has been involved in the tax and accounting business for 30 years. For the past 10 years Mark has operated Linzmeier Business Solutions, LLC a CPA firm in Green Bay, Wisconsin. The business has grown over the years and provides a variety of services including audits/reviews/compilations, income tax planning and preparation, business consulting and overall business transition planning.

Mark was raised on a dairy farm in Manitowoc County, Wisconsin. The Linzmeier family has deep roots in Kewaunee County, and Northeastern Wisconsin in general. Mark is a Valders High School graduate. He received his Bachelor of Science degree in Managerial Accounting from the University of Wisconsin–Green Bay.

Mark has a unique perspective on business management that separates him from the average accountant or CPA. Most CPAs, including those at the “Big” CPA firms, do not have any practical hands-on business management experience. They have primarily been in public accounting their whole careers and are mostly “history recorders”.Mark has taken a different route from his peers. He has extensive, high-level experience in many areas besides his CPA firm. His customers compliment him regularly on being a true business advocate in helping suggest positive initiatives which help them be successful in addition to just “recording history”. Mark understands that recording actual financial results is important, but to truly impact what is recorded, businesses need to make informed decisions in advance. Mark’s experience below helps customers do just that:

  • Mark was Executive Vice President and spent over 7 years in executive management of the Smithfield Beef Group (Packerland Packing Company) in Green Bay, Wisconsin. The Company had annual revenues of over $3 billion, was the fifth largest beef processor in the USA and the largest cattle feeder in the world during his time there. His primary responsibilities centered around decision making to create a successful and profitable company, while being a responsible company to community, employees and the environment. In this position, he was responsible for daily projections, managing operations, overseeing all accounting functions and managing many departments in a highly volatile commodity industry. Mark also was in charge of all mergers and acquisitions activity, as well as the price risk management of the cattle feeding operation.
  • Mark spent 6 years in commercial lending for what is now known as US Bank. He spent time in Denver, Co and Minneapolis, MN working with customers across the USA in all industries with loans from $500,000 to $250,000,000. The experience from the lenders perspective has proven beneficial when Mark represents the borrower today.
  • Mark also founded and developed MARGINSMART, which is the dairy industry’s leading financial projection program. MARGINSMART is a web-based program which is customized to each dairy farm and updates market information continually to essentially provide real time budget projections to each customer. The company is based in Green Bay, WI and serves dairy farmers across the USA.
  • Over his career, Mark and his wife Peggy have also managed and operated their own dairy farm, vegetable and canning operation, vacation rental homes and other rental property.
    Mark and his wife Peggy have 5 wonderful daughters. Outside of work, Mark enjoys family time and events, as well as gardening and landscape projects. Mark can also be contacted at his Linzmeier Business Solutions email at
