Excellent Attorney - Probate and Estate Case
I was Sean Greengard’s client for over 15 months. What started as a routine probate matter evolved quickly into a long and complicated estate dispute. Throughout the entire case Mr. Greengard advised me, kept me informed and developed strategies that ultimately resulted in a successful resolution. Even had the outcome not been what I wanted I was fortunate to have an attorney with Mr. Greengard’s wisdom, integrity and perseverance. He successfully led me through the most stressful legal battle I could have imagined.
