We built our reputation on integrity and trust, because doing what's right for you is right for us.

Clients First. Always.

Welcome to Mattern Wealth Management where clients come first - always. Based in Lawrence, Kansas, Mattern Wealth Management is an independently owned and operated, SEC registered investment advisor dedicated to the fiduciary standard. This means we always act in our clients’ best interest.

While we are competent professionals who put our client first – always - we are much more than that. Everyone connected to Mattern Wealth Management understands that we build our reputation on integrity, trust and accountability.

At Mattern Wealth, we hold tight to our Midwest values, keeping the foundational principles of Friends, Family, Health and Wealth close in our hearts and minds. Our mission is to build a deep, lasting relationship and handle all of the details of managing your financial life (wealth), so you can focus on your friends, family and health.

We want you to enjoy a sense of freedom, comfort and confidence, relying on us to handle the wealth management strategy and financial planning details so you can live the life you want –  without the burdens that can come with managing the family fortune. No matter how much money you’ve saved and accumulated over the years, this is the nest egg you’ve worked so hard to build and secure. We take our responsibilities to you seriously and will treat you as if you are a family member or special friend.

No matter where you are on your journey, we can guide you to financial independence. Our goal is to help you reach a level of financial security that will enable you to achieve your objectives and create a legacy for your family for years to come. Using solutions tailored to your specific needs, we will strive to help you move from a life of success to a life of significance.

Our comprehensive approach
centers on you.

Our Approach

We know that concerns about your financial situation can easily develop into stress without a trusted advisor who can help develop the right plan for you – and help you stay committed to the plan even when market “noise” might tempt and lead you astray. That’s why we see ourselves as partners on your path to financial independence, helping you create a future that includes not only financial security as you live out your life – the way you want to live it – but also planning for your legacy.

Common “middle-of-the-night concerns” are:  

  • Will I run out of money?
  • Do I have enough to retire – and stay retired?
  • What if there’s a recession?
  • What will my retirement look like?
  • What will my legacy be when I’m gone?

When clients raise these questions, we always go back to the plan, where we can discuss scenarios and probabilities that take various events into consideration and we can help them regain peace of mind.

Here's what we’d like you to know about us and what we do:

  • Beholden only to you
  • Referred by many CPAs
  • Laser-focused on the financial details so you don’t have to
  • Concerned about your comfort and overall well-being
  • Will provide routine temperature checks – yours AND the economy
  • Will add value through tax minimization (tax alpha)
  • Will provide a time-tested investment process
  • Our goal is to bolster your confidence in your retirement plan and to empower you to live your dreams through a planning process that supports your success

Bringing Midwest values and a strong
work ethic to everything we do.
