Biography

Nearly 45 years ago Joseph F. O'Neil opened up his law office to countless immigrants in the Greater Boston Area. O'Neil's mission to help people navigate the U.S. immigration system, remains the driving force behind O'Neil Hauser Mansfield, P.C. today. After over a decade of experience working with O'Neil, I took over as president of the firm in 2008. We continue to follow our founder's tradition, while adapting to the ever-changing face of the American immigrant. As president of O'Neil Hauser Mansfield, P.C., I supervise a skilled team of immigration lawyers and paralegals as we represent both individuals and corporations in all aspects of immigration law. From advising companies in immigration compliance, to helping families obtain green cards, I have extensive experience with the U.S. immigration system. I am fluent in Spanish and proficient in Portuguese, allowing me to communicate with many immigrant clients on a direct and personal level.
