John Siciliano’s Comments on Business Law

“Much of my work centers on serving owner-led businesses. Hemenway & Barnes offers a unique perspective on the complex issues that owner-led companies often face. These owners are challenged with managing the day to day business, while keeping in mind the long term needs of their business partners and/or families. We understand this dynamic and are able to bring years of experience to both areas to advise our clients.”
