I am an attorney at Gross, Romanick, Dean & DeSimone, P.C., where I assist clients our clients in resolving business-related disputes. My practice includes breach of contract disputes, business torts, debt collections, commercial leasing disputes, and partnership disputes.
I also assist our clients with general corporate and transaction matters, including entity formation and governance, regulatory compliance, commercial transactions, and mergers and acquisitions (M&A).
My goal is to make the legal process as smooth as possible by keeping clients informed and supported at every step. I enjoy helping clients find practical solutions to legal issues without overcomplicating matters. Above all, I strive to be a trusted partner to my clients by being responsive, communicating early and clearly, and delivering practical, effective legal services.
Before becoming an attorney, I served on active duty in the U.S. Navy, earned a business degree from the Pamplin College of Business at Virginia Tech, and completed my J.D. at American University Washington College of Law, where I focused my coursework on commercial and corporate law.
I am licensed to practice in Virginia and the District of Columbia.
