Our law firm was established by attorney Sasha Westerman-Keuning, one of Florida's leading immigration lawyers.   Sasha is one of only 80 lawyers in the State of Florida who holds the distinction of being a Board Certified Expert in Immigration & Nationality Law.  Sasha has practiced immigration law exclusively since 2009 and worked as the Senior Immigration Associate at several of Miami's top law firms before opening her own law practice in 2013.  She has been named a "Super Lawyers" Rising Star (Florida) for the years 2018-2023, a prestigious designation reserved for less than 2.5% of all Florida lawyers.  She graduated with honors from Boston College and the University of Miami School of Law.  She applies years of experience at leading immigration law firms to her law practice, providing innovative legal solutions to even the most complex immigration cases.
