About me

Mr. Phelan said he’s drawn to practicing family law because of the personal connection it allows him to build with his clients. Unlike other areas of the law, family law allows an attorney to truly connect with, and thus advocate for, a client.

“I enjoy working with my clients, who are usually in a difficult position in their lives, to help them reach a resolution that is not only in their favor, but also allows them to put their minds at ease and continue on with their daily lives,” Mr. Phelan said.

  • David A. Keightly

    I endorse and recommend Bill. I serve as local counsel with Bill. He is very well organized in a case with a huge amount of paper. His research is thorough, and his writing is good and effective. He's still a young guy, but he will be lead counsel in no time.

  • Chris Gowen

    I may be biased but I believe Mr. Phelan is the best advocate in DC for clients with Social Security or other disability benefit issues.
