About Me
Currently
I am the managing partner of Thyden Gross & Callahan, LLP, a law firm in Chevy Chase, Maryland. I am a mediator, collaborative lawyer and arbitrator. I have authored or co-authored three books, “File for Divorce in Maryland, Virginia and the District of Columbia”, “Money and Divorce” and “Fathers’ Rights (The Best Interest of Your Child Includes You)”. I write a column called “Daily Answer Desk” for DivorceNet.Com, and two blogs, “Maryland Divorce Legal Crier” and “Fathers’ Rights (Not Just Every Other Weekend)”. I lecture on family law at various seminars and have appeared on television and radio. I was selected among top lawyers in Maryland and DC by Super Lawyers Magazine and Washingtonian Magazine and I am rated “Superb” by Avvo.com and “AV Preeminent” by Martindale-Hubbell.
Education and Experience
I graduated from the University of Missouri in Columbia in 1970 with a Bachelor of Science in Chemical Engineering. Procter & Gamble hired me to work in its International Division in Cincinnati, Ohio. I was there for about a year when Uncle Sam drafted me for the Viet Nam War. I spent a year producing television shows for the Signal Corp. at Fort Gordon, Georgia, and another year working on long range patrol rations as a chemical engineer at the U.S. Army Labs in Natick, Massachusetts.
When I got out of the army, I went to law school at the University of Missouri in Columbia, where I made the law review and clerked for the Public Defender. I graduated with a JD in 1975.
The Federal Communications hired me to come to Washington, DC, and work as an attorney in the Broadcast Division. After two years at the FCC, Satellite Business Systems, a partnership of IBM, Comsat and Aetna hired me to work in its Legal Business Department. During that time, I earned a Master of Laws in Taxation from Georgetown University in 1982.
Other Experience
Trammel, Rand, Nathan & Lincoln hired me from Satellite Business Systems after two years, and I set up my own practice a year after that. I merged that firm into Amram, Hahn & Gross where I was the managing partner and worked on real estate tax appeals. Whiteford, Taylor and Preston hired me from that firm, and I co-founded Thyden Gross & Callahan, LLP, a year later.
Interests
I am a past president of Metropolitan Washington Mensa and the Collaborative Law Society. I have served on the Board of Directors of Sheet Metal Manufacturing, Inc., Affiliated Community Counselors, Inc., and the DC Capitols Track and Field Club. I play racketball and I live in Chevy Chase, Maryland, with my wife, two sons and a cat.
