    Tom and I worked together at the U.S. Patent Office for about two years and I found him to be knowledgeable and personable. He was excellent at giving newer colleagues advice and always very professional. He continues to maintain relationships with many of his former USPTO colleagues. Since leaving the USPTO 10 years ago, Tom has worked in multiple areas of IP law. He also keeps abreast of changes in the law and has written articles and given talks on these as well. He puts a great deal of effort into his work and remains in contact with the office even while at home, making sure to check his messages first thing in the morning and several times during the evening. Tom enjoys fishing, naval history and is a former NCAA athlete (sailing.) He is married and lives with me (his wife) and our 4 small children in Alrington, VA.
