Washington County's three resident Republican lawmakers attended the announcement but stopped short of endorsing Myers in the primary.
"He's a very classy man. The thing I like best about him is he's got a great reputation among the business community for his integrity. I think that's important for a person who aspires to be in politics," Sen. Donald F. Munson, R-Washington, said afterward.
Myers faces a Sept. 10 primary against Republicans Vikki Nelson, 58, of Clear Spring, and William Wivell, 37, of Smithsburg.
The winner of that primary likely will face Peter E. Perini Sr., 38, of Hagerstown, who is the only Democrat to file in the newly opened District 2A that runs across the top of Washington County from Big Pool to Cascade.
At the announcement, Myers introduced his wife, LuAnn Myers, and their four children, who range in age from 16 to 27.
His three grandchildren, who range in age from 1 month to 2 years, wore red T-shirts that read, "vote for my pappy."
Myers said he has received good response from a fund-raising letter he recently sent to area businesses, but declined to say how much money has come in so far.
Myers filed his election paperwork on Monday and has established a Web site, www.votele roymyers.com.
Myers thanked members of his campaign committee, including retired Clear Spring High School Principal John Peckyno, Hagers-town businessman John Barr and former economic development marketing director Tom Riford.
In the prayer, the Rev. Gerald Carbaugh blessed Myers' staff and campaign committee. He said God wants to "raise up Godly men and righteous men" like Myers to run for office.
