Mark Lasseigne, CFP®, CMT®, CKA®


Mark is a Certified Financial Planner™, a Chartered Market Technician ®, and a Certified Kingdom Advisor ®. He is passionate about helping investors align their investments and financial decisions with their faith.

Mark has always around business and finance. Shortly after finishing college, he successfully formed and ran a business for several years. But his passion was in the financial markets. Mark began working as a financial advisor in 2007, and first discovered Faith-Based Investing in 2010. Since then, he’s made this the foundation of his practice.  Mark founded Financial Cornerstones in 2019, becoming a true fiduciary as an independent advisor. This has given him the ability to work as a market technician, a biblically based financial planner, and a specialist in Faith-Based investing.

Mark lives in Spring, Texas with his wife, Kendall. They have been married for 37 years and have successfully raised three adult children. He is a member of Sts. Simon & Jude Catholic Parish and donates his time and resources to both his church and several Christian organizations. In addition, he’s a member of Kingdom Advisors and the National Association of Christian Financial Counselors.

My Personal Commitment to You

As a Christian financial advisor, my work centers on a belief of utmost importance to me—that God truly owns it all. I believe we are called by God to be good stewards of the resources we’re afforded, and my passion is fulfilling that call.  I’m committed to helping my clients be faithful and wise stewards through discernment, a high level of competence, and insight gained from years of experience. The heart of every client relationship, however, is trust. Serving in your best interest is my highest priority as a fiduciary and on personal principle. If it seems like we may be a good fit to work together,  I encourage you to get in touch.

My Commitment to Our Clients

I am absolutely committed to serving our clients to the best of my ability and putting their interests before my own. However, I believe that my ultimate performance review will come at the end of my life when I meet God face-to-face. My highest desire is to hear Him say, “Well done, faithful servant” (Luke 19:17). Because of this belief, I am committed to helping you with honesty and integrity.
