Built on Experience and Real Relationships

Tiarks Financial has been part of this corner of Minnesota for more than two decades — not because we set out to build a big firm, but because people kept coming back and telling their neighbors. That's still how most of our client relationships start.


Nathan and Andrew Tiarks both hold the AIF® designation, which means they're held to a fiduciary standard — legally required to put your interests ahead of their own. In practice, that looks like honest answers even when the honest answer isn't what someone hoped to hear, and recommendations that make sense for your situation rather than for our revenue.


We don't have a minimum asset requirement. That's a deliberate choice. The people who need clear retirement guidance the most aren't always the ones with the largest portfolios, and we'd rather have a real conversation than turn someone away at the door. What we care about most is that you leave every meeting understanding more than you did when you walked in — whether that's your first appointment or your fifteenth.

Our mission is to help people make important retirement decisions with confidence by providing personalized guidance, practical education, and a clear plan built around their goals.

Personalized Guidance

No two retirements are exactly alike. You'll receive recommendations designed around your goals, benefits, family circumstances, and retirement vision rather than a generic template.

Education First

Retirement decisions are easier when you understand your options. We focus on helping you make informed decisions by explaining complex topics in a clear and practical way.

Long-Term Relationships

Retirement planning is not a one-time event. We build ongoing relationships that adapt as life changes, helping you stay aligned with your goals over time.

Responsiveness

Questions rarely arrive on a schedule. We strive to provide timely communication and guidance when important decisions arise.

Proudly Serving Southeast Minnesota Families

For more than 20 years, Tiarks Financial has worked with individuals and families throughout Southeast Minnesota who want retirement guidance that feels personal, understandable, and practical.


Our proprietary Retirement Roadmap walks you through every major decision — pension elections, Social Security timing, 403(b) rollovers, and Medicare enrollment — so nothing gets missed and nothing gets rushed. Experience working with Mayo Clinic employees and retirees has become one of the firm's strongest areas of focus because of the unique retirement decisions these professionals face.


Whether someone is years away from retirement or already retired, our goal remains the same: help them understand their options and move forward with confidence.
