At our firm, we have the client—and only the client—in mind.

Our reasons for becoming financial professionals are deeply personal. We repeatedly saw many friends and family struggling to find the help they needed to map out their financial future. We are confident that with our understanding of personal finance, coupled with our training as financial professionals, we can help people better prepare for the future. After years in the business, we have developed a reputation for educating individuals in an easy-to-understand manner so they can grasp personal finance and use those concepts to pursue their financial objectives. We feel a commitment to our community.

At our firm, we have the client—and only the client—in mind.

Jason Harness, Founder of Harness Financial, is an advocate, accountability partner, and financial strategist for his clients.  He focuses on wealth management, financial planning, and the integration of tax mitigation strategies to help deliver solutions that will impact the outcome.

Jason believes that a comprehensive understanding of his clients’ financial lives and periodic reviews leads to better results. He encourages his clients to think about how their priorities could evolve and helps them create strategies that respond to their changing needs.

In addition to those preparing for, or in, retirement, Jason’s services are especially valuable to business owners.  He has merged the parallel paths of growth taught by the EPI in the CEPA credentialing alongside the quantitative, process-driven six steps instilled by the IEPA in the CBEC credentialing.  The results have assisted his business owner clients in developing plans and strategies that align with their specific exit goals.

Jason  views the financial process as a team sport and regularly collaborates with his clients’ other advisors.  If you are in need of upscaling, or expanding your team, the team at Harness Financial can make several introductions on your behalf.

Jason earned his Certified Family Business Specialist (CFBS) designation in 2018 and his Certified Exit Planning Advisor (CEPA) designation in 2019.  His Certified Business Exit Consultant (CBEC) was earned in 2023.

I started in the financial world after a 22-year career in IT, where I wore many different hats. I first started working in IT at a small, local computer store and internet provider. I held many different roles over the years beginning from the help desk, working up to a senior engineer and manager. I worked on implementation, ongoing support, and decommissions of several integrated systems which affected thousands of users, and sites all over the country.

Many of the projects that I oversaw had no margin of error when it came to downtime. Having a solid plan, built on experience, collaboration, and testing was key to ensuring success. 

I joined Harness Financial in 2019, where I work with my brother, Jason Harness. We have a team of administrative professionals who make sure we are delivering top notch service. Our total scope of work includes Insurance Strategies, Portfolio Analysis, Retirement Planning, Financial Planning, and Business Exit Planning. 

I was always learning when I was in IT and I brought that passion to the finance world, where I continue my education. In 2019 and 2020, I passed the Securities Industry Essentials, Series 6, and Series 63, Series 65, and Series 7 exams. In 2021 I earned the  Certified Exit Planning Advisor (CEPA) designation. I completed my Property and Casualty license in 2021. I also earned the Retirement Income Certified Professional (RICP®) designation in 2021. I continue to take courses and add to my knowledge.

When I am not focused on my clients, I am spending time with my family. I have two daughters named Mia and Evelyn, as well as a son named Cruz. We live in Ballwin, Missouri. As the head coach to a softball team, and father to another softball player, you can usually catch us at a ball field around the area. I also CrossFit in the mornings. I received my scuba diving certification in 2022. My family loves to hike and explore new places. We are also avid foodies and can find us trying out a new restaurant. If all else fails, you can find me running the trails around the area or competing in obstacle course races such as Spartan Races. 

I am a big believer in team sports and what benefits they bring to our kids, and I bring that passion to the Sports Commission Associates, a 501(c)(3) organization, as a board member. I co-chair our annual trivia night and I volunteer for our other events. I love giving back to our community and I am a member of the West County Chamber of Commerce.
