About

  • I was born in Busan, a large port city in South Korea, in a working class neighborhood
  • Busan was one of only two cities in Korea not captured by the North Koreans during the Korean War
  • Part of the local culture there was to sleep on a wooden pillow, where it was believed to improve the body’s alignment and release tension
  • I sometimes think of that wooden pillow as a metaphor
  • What can appear to be hard and unyielding, can in time reveal great benefits
  • I know that some of those early hardships toughened me up and made me value the practical and simple things in life as well as making me a firm believer in looking beneath the surface
  • I was thrilled to be able to emigrate to the U.S. territory of Guam when I was six years old
  • Like so many others, I saw America as a place of endless possibility
  • There, I had ample opportunity to witness U.S. soldiers on maneuvers and think about how I could achieve a life of service
  • The military was not for me, but I decided then that the best way for me to help people would be through the framework of the law. (By the way, I offer reduced fees for those in the active military.) I studied hard and was accepted into Smith College where I spent four years in beautiful (and frigid) Massachusetts studying Psychology
  • Though the law would be my career, it was people that was truly my business
  • After an incredible junior year studying Japanese in Nagoya and Tokyo, I graduated from Smith College in 1995
  • I then went to D.C. to study law at American University Washington College of Law
  • I lived in a tiny apartment and rode my bike up the steep hill to the law school where it soon became apparent that there was a clear path for me
  • I wanted to help people in my community through the general practice of the law
  • When I started my own firm, I knew that its priority would be on helping regular people
  • My clients include lawyers, doctors, construction workers, landscapers, teachers, students, housekeepers, and soldiers
  • To me, their occupation is mere window dressing
  • In my mind, the housekeeper’s work is just as valuable as the doctor’s work
  • They come to me with a problem and I help them find the best solution
  • I firmly believe in the rule of law as one of the hallmarks of democracy, but the law is an imperfect instrument and justice is not a given
  • I see my role as mitigating the many unfair things that can arise when the blunt instrument of the law is applied to an individual who has unique circumstances
  • I believe that everyone deserves a second chance and it is my job to protect the average person from the ruthlessness that can sometimes emerge in the courtroom when the law is applied heartlessly
  • If you were to talk to the people who know me best, they would say that the way I approach cases are with tenacity, extreme focus – to put it in plainer words, I am like a dog with a bone, I give it my all and I don’t give up – and without bias
  • I still think about that wooden pillow
  • A hard exterior may reveal something far more complex
  • So, it is with people
  • I have successfully litigated criminal, serious traffic (DUI/DWI), and civil cases for over 20 years
  • From 2013 to 2023, I received AVVO's Superb 10.0 rating and its Clients' Choice Award
  • I am AV Rated by Martindale-Hubbell, which is the highest level of professional excellence at which a firm can be ranked by its peers, and am a recipient of their "Client Champion-Gold & Platinum" Award (2019-20 23 )
  • I have been selected for inclusion in the following lists: Rue Ratings' Best Attorneys of America (2015-20 23 )
  • Maryland and Washington, D.C
  • Super Lawyers® (2010-20 23 ) (limited to 5% of Maryland and D.C. lawyers)
  • “Top 100 Trial Lawyers in Maryland" (2010- 20 23 ); “Top 100 Criminal Defense Lawyers in Maryland" (2013- 20 23 )
