Welcome to our law firm website. Ferguson & Wilpon was founded in 2001. We are a general practice law firm in Olney, Maryland, a suburb of Washington, D. C. located about half way between our nation’s capitol and Baltimore, Maryland. Many of our clients are businesses located in or individuals who live or work in the greater Olney community, which includes the town of Olney itself and the surrounding areas of Ashton, Brookeville, Cloverly, Derwood, Gaithersburg, Laytonsville, Leisure World, Rockville, Sandy Spring, Silver Spring, and Wheaton. All of our attorneys live in Olney. Thus, we have developed a reputation as Olney’s hometown law firm. Although we like our reputation as Olney’s hometown law firm, our client base is much larger than just the Olney area. The firm represents clients throughout the State of Maryland, and in particular, between the cities of Washingon, D.C. and Baltimore, Md. This includes the city of Columbia and the surrounding Maryland counties of Montgomery, Howard, Prince George’s, Baltimore, Anne Arundel, Carroll and Frederick.

Sharon T. Diamant has been working as an attorney for over twenty-five years. In October 2000, she became a prosecutor in the Montgomery County State's Attorney's Office. She left the state's attorney's office in 2002 and practiced Criminal Law in Hillsborough County, Florida for two years before returning to the state's attorney's office in 2004. Ms. Diamant remained at the Montgomery County State's Attorney's Office until 2010, when she opened her own office and went into private practice. While a prosecutor, she handled a wide variety of matters in the District Court Unit, including bad checks, burglary, theft, drunk driving and other traffic offenses, assault, and violations of protective orders (Gazette). In the Juvenile Division, she handled sexual abuse cases involving juvenile offenders. She handled one famous juvenile matter involving a youth who had molested several children in his neighborhood which ultimately led to the first-ever sexual offender legislation which would require juveniles engaged in sexual offenses to register as sex offenders (Washington Post). In 2007, Ms. Diamant joined the white-collar crime team in her office, where she handled the prosecution of a myriad of crimes, including large-scale thefts, embezzlements from employers and the federal government, misappropriations, as well as the investigation of police officer-involved shootings and crimes involving public officials. For the past fifteen years, Sharon has focused her practice on criminal law and domestic law. She appears regularly before Magistrates and Judges on all issues surrounding criminal law and domestic law, to include: contested and uncontested divorce, child custody, child support, peace and protective orders, and post-judgment issues. Sharon also handles cases that cross over between criminal and domestic law. Sharon was featured on WJLA 7 News in a case involving a grandparent's right to custody of a grandchild where the mother is deceased and the father is a convicted criminal. Sharon also handled a case of a woman accused of attempted murder but who never intended to hurt anyone. That client is now receiving mental health treatment, as opposed to being locked up in a jail. Sharon is a client's biggest advocate and at the same time acts as a mentor and friend. She personally answers her phone calls, answers all emails and texts, and is always available to her clients. She is an experienced litigator with 25 years of trial experience, but she also mediates for clients and promotes non-litigation strategies, where appropriate. Sharon is a 1999 graduate of the University of Dayton School of Law and is licensed to practice law in the State of Maryland, the State of Florida, and the US District Court in Greenbelt, Maryland. Sharon was also admitted to the US Supreme Court. She has been selected to the Super Lawyers list for the State of Maryland in 2012, 2013, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 and 2024. She is a member of the Montgomery County Bar Association, the Women's Bar Association, the Sobeloff Society, the Collaborative Divorce Law Society, the National College for DUI Defense, the Montgomery County Ethics Committee, the Montgomery County Criminal Law Society, and the Inns of Court. Sharon also sits on Montgomery County's Judicial Nominating Commission and is a board member with the Sobeloff Society. She has won Avvo's Client Choice Award and has a "superb" rating on Avvo.com. We are open 24/7, so give us a call today at 301-560-2685.
