Johni served as the President of the Charitable Estate Planning Institute from 2012 and retired in 2016. She and a group of Thompson & Associates colleagues formed the Institute in 2012, as a means for estate planning professionals from across the country to gather annually to discuss advanced topics specifically geared towards estate planning. 

Johni frequently lectures on a national basis to groups on estate and charitable planning, probate, living wills, annuities, life insurance, retirement planning and IRAs, as well as income, estate and gift taxation. Her quick wit and engaging personality make the often-complicated topics of estate planning fun and easy to understand.
