Originally from Nashville, Indiana, David and his wife, Erin, planted roots in Nashville, Tennessee, in 2013. He graduated from the University of Taylor with a degree in Biblical Studies. Prior to joining Southwestern Investment Group, David worked for Thrivent Financial. He holds the Series 7 and Series 66 registrations, as well as Tennessee life, health, annuity, and long-term care insurance licenses.



David primarily focuses on updating clients regularly to their financial picture and helping clients reach their goals. One of the main things that brought David to Southwestern Investment Group was the unwavering commitment to putting clients first. Southwestern Investment Group and Raymond James are both independent and therefore not tied to any one group of products or services.  Because of this, David is able to ensure that every recommendation he gives is done as a fiduciary. 



David loves getting into the details and implementing the tax-efficient financial planning strategies that help clients keep as much of their hard-earned money as possible. His biggest passion is helping clients dream about their legacy and ensuring that each part of a client’s plan makes sense for their individual situation.



When not in the office, David spends time serving at his church, with his family, and traveling—although traveling is much harder with a young family. David and his wife have a two-year-old girl, Wren, and they just welcomed a baby boy into their family in March 2019. 

Neither Raymond James Financial Services nor any Raymond James Financial Advisor renders advice on tax issues, these matters should be discussed with the appropriate professional.
