Dennis Delaney’s Comments on Challenges Clients Face

"My job often addresses the intersection of multiple challenges for my clients where solutions require deep expertise in any number of areas such as wealth management, legal issues, tax planning, and navigating family dynamics. In today’s hyper-specialized marketplace, all too often clients are left to knit together the separate advice they receive from multiple experts who don’t see beyond their own areas of expertise. At Hemenway & Barnes, we pride ourselves not only for our deep expertise in these critical areas, but also for our vast experience in connecting it all together. The value we bring is enabling clients to make the most informed and strategic decisions possible, which in turn helps create and preserve wealth for themselves and their families."
