Originally from Columbus, I have lived in Georgia my entire life and moved to south Atlanta in 1994.  After graduating from Oglethorpe University in 2011, I found myself drawn to the financial services industry as it had always been an interest of mine.  I began my career with another large mutual insurance company then moved to a small broker dealer before joining Mac's team in May, 2015.

My role and expertise is to assist our clients in developing their holistic, customized financial plans and investment strategies. 

I have a passion for fitness and dedicate myself to maintaining the high standards which I have set for myself.  Should you find me outside of work or the gym I am likely spending my time with friends or working on projects around my new home.
