How We Got Here

Client Centered

The Landmark brand of a cairn embodies a financial map for our clients. A cairn is defined as a mound of stones built as a navigational aid for travelers. Cairns originated in Scotland, used by migrants to signal safe passage on their cross country treks. Our financial plans serve as mile markers we use to ensure our clients are always headed in the right direction as they embark on their life journey.  

While our primary objective is helping guide your journey towards abundance, we are on our own journey as well. In 2019, three well-established Thrivent Financial practices joined forces to create Landmark Wealth Management Group, becoming one of the largest investment, insurance, and financial planning practices in Thrivent’s history. Our five founding partners (two in Minnesota and three in California) have over 150 years of combined experience in the financial services industry. 


But our journey isn’t ending there. We are adding locations and bringing on younger advisors and team members with diverse experience and specific areas of concentration to help with college planning, business continuation planning, retirement strategies, risk management, and estate and charitable planning (just to name a few). We’re proud to say that our team members are some of the best and brightest in the financial services industry.

Most importantly, our journey is focused on you. We’re here to help you define your values and goals and navigate to them using the financial landmarks on your path toward abundance.
