Special Message

It is with profound sadness that I announce the passing of my brother, Dennis O'Sullivan. Dennis and I started Insignis Financial Group, LLC just over 5 short years ago after working together since 1999. On July 13, 2017 he succumbed to his battle with brain cancer. He was 55 years old. Dennis was a member of the Guardian Life Insurance family for the past 11 years and he passionately served his clients in the financial services industry for over 30 years. He took great pride in the work that he did for he clients and he was especially proud being part of the faculty for The Living Balance Sheet. Dennis was a loving husband to Dawn, a devoted father of Jaclyn and Danielle, a cherished brother, an adored uncle, and devoted friend to so many. He was my business partner, my brother, and my best friend and I will miss him dearly.

Dennis was know for his love of life and his passion for music, travel, and wine. Dennis enjoyed playing golf with his daughter Jaclyn and earned his black belt with Danielle. He always prioritized his family and friends. Dennis was an active member of Saints Philip and James Church, where he served as lector and Eucharist minister.
