Jeff A. McMahan, CFP®


Jeff has been a financial professional for more than 30 years. After starting his career in Indianapolis, he eventually moved to Silicon Valley where he spent 10 years as an investment advisor for Menlo Financial Services. He was also active with the NETWORK, an early financial advisory association based in Menlo Park, and spoke frequently to advisors on how to deliver premium client service. In 1994, Jeff founded McMahan Capital Management in Redwood City, CA, and in 1998, made the decision to move the practice back to Indiana to be near family. He continues to work with many of his original California clients and others throughout the Midwest.


In 2017, Jeff and McMahan Capital were recognized with the first Legacy Award presented by the client-service technology platform Junxure. Jeff was one of three financial advisors who began development of what in 2002 became Junxure, the leading client service platform in the financial services industry.


Jeff was a trained volunteer for CERT (Community Emergency Response Team), a national program which educates volunteers about disaster preparedness and trains them in basic disaster response skills, including team organization, fire safety, light search and rescue, and disaster medical operations.


For a number of years, he was also involved with Miles for Myeloma, an awareness- and fund-raising cycling tour sponsored by the Simon Cancer Center at Indiana University School of Medicine.


Jeff holds a BS in finance from Indiana University, and completed the requirements to become a CERTIFIED FINANCIAL PLANNER
professional at the College for Financial Planning. When not working, Jeff enjoys concerts, art galleries and long walks with Dakota & Annie (two amazing Goldendoodles.)
