Who We Are

About The Firm



Our Story

Barnett, Lerner, Karsen, Frankel & Castro, P.A. was founded in 1995 by David C. Barnett, Esq., and Barry R. Lerner, Esq.   Over nearly three decades the firm has grown and expanded.   Beginning in 2010, Mr. Barnett and Mr. Lerner realized the need to expand with experienced attorneys.  Brian Karsen, Sam Frankel, and Ana Castro joined the firm, bringing vast experience to the practice.  Mr. Karsen, Mr. Frankel and Ms. Castro became named partners and the firm continued growing by adding two additional partners: Ms. Alvarez and Mr. Zobec.    Currently the firm has 8 attorneys who exclusively represent plaintiffs.  Since members of the firm have prior experience representing employers and carriers, our attorneys have strategic trial and litigation advantages over employers and carriers and they use this knowledge to benefit our clients.

Since inception, the firm has been committed to litigation excellence.  While other firms practice law, Barnett Lerner has helped define the law through our extensive litigation and appellate history.  Our attorneys have vast, extensive experience representing employees and we fight to ensure their legal rights are protected.  Members of the firm are viewed as leaders in their field and most have been published, spoken at educational conferences and led legal associations.

The firm represents civilian contractors throughout the world; regardless of nationality and we have a national litigation presence.  The attorneys in the firm have litigated hundreds of cases and have handled appeals in numerous State and Federal jurisdictions throughout the United States.  Many of the firm appeals have been published and serve as legal authority.

The BLKFC family's mission is to tirelessly advocate for clients with honest and creative collaboration and curious skepticism to provide quality representation that exceeds expectations.  To learn more about the experience of each member of the firm, please review their bios.
