My Story

Allow me to introduce myself, my name is Gregory Sinatra – father, son, husband, and Financial Advisor with the Avonlea Financial Group of Thrivent. I became a financial professional to guide families to be the best stewards of all that God has entrusted and blessed them. In 2017, I launched my own financial planning practice in Marietta, Georgia. In 2022, in collaboration with my business partner, Katherine Gross, the Avonlea Financial Group was created.


I am proud to be a Thrivent financial professional. I aim to provide personalized financial guidance to people at all stages of life. At Thrivent, we view money not as a goal, but as a tool — one that can afford you a life rich in meaning and gratitude. We believe humanity thrives when individuals make the most of all they've been given. My team and I are here to help you do just that.

Paying It Forward

It is my mission to uplift my community and ensure I am taking steps toward creating a better tomorrow. I give back through service with my local congregation and Scouts BSA - Atlanta Area Council as a Unit Commissioner and Merit Badge Counselor for Personal Management, Music & Bugling. I also have the opportunity to lead sessions at the University of Scouting and recruit adult leaders for several Merit Badge Summits offered by the Atlanta Area Council. Through my connection with the scouts of Boy Scouts of America, I partner with cause organizations such as The Sandwich Project to address food scarcity needs in metro Atlanta. Community is an investment that I believe add value to the world and I have found purpose in spreading generosity through action.
