Tyler (Ty) Mueller

Partner, CPA
BA, Accounting & Finance — University of Wisconsin La Crosse

Ty brings over 16 years of experience in accounting and taxation, with a career spanning diverse roles in both public accounting and private industry. His early career included time at a large regional CPA firm, where he refined his technical expertise, followed by serving as Controller at a high-growth healthcare company. He later became Vice President of Finance at a health technology startup, where he built the accounting, finance, and tax functions from the ground up.

Nearly five years ago, Ty founded TYM Financial out of a desire to return to working closely with small businesses, their owners and shareholders, real estate investors, and other individuals. In July 2026, TYM Financial was merged into Integro CPA. His mission has been to bring back the approachability, personalized support and client-centered focus often lost in traditional public accounting and tax firms.
‍
At Integro CPA, Ty delivers deep expertise in small business accounting, tax, and tax planning. He emphasizes that clean, up-to-date bookkeeping and accounting are the best starting point for effective tax planning. Ty also provides clients with insight into their financial statements, helping them better understand their numbers and make informed financial decisions. Leveraging strategies such as entity selection and optimization, retirement plans, QBI optimization, cost segregation studies, and the Augusta rule, Ty has helped his clients realize significant tax savings.

A proud Wisconsin sports fan, Ty rarely misses a chance to attend Brewer games, golfing, and swimming. His greatest joy, however, comes from spending time with his wife Rachel and three daughters, Blake, Lilah, and Dawson. Ty currently resides in Hartland, Wisconsin.

David has over 10 years in the tax world, with his most recent experience at a boutique CPA firm specializing in high-net-worth individuals and fiduciary tax services. Prior to that he spent four years working at one of the largest independent wealth management firms in the United States where he helped grow the tax practice 7x during that time. Before he helped grow that practice, he spent time at PwC, Clifton Larson Allen and Salo, a Korn Ferry company honing in his tax and accounting skills.

David specializes in tax advisory, planning, and preparation for high net-worth individuals and has deep expertise in tax planning with Roth conversions, solo retirement plans, stock compensation, and charitable giving. He is also very experienced in gift, estate, trust, and foreign reporting tax situations. David is committed to delivering the highest quality work and ensuring excellent service to his clients. He gets recognized by his clients for his work, and many of them are his biggest fans.

David loves playing golf, board games (he doesn’t like to lose), hiking, and traveling – he even spent a semester in Australia. He continues to run after his wife, in often futile attempts to keep up with her on long distance runs. He tried to run a marathon in 2020 but due to the pandemic there was no crowd to cheer him on and that may have sunk a career as a marathoner.David currently lives with his wife and son (Declan-2) in Williams Bay, Wisconsin with their second child coming this December 2025.
