Mike Catelinet first played in the Baltimore Philharmonia Orchestra in the 2003 season. He and his wife, Shira, re-joined in 2021, and he has served as Principal Second Violin since. Mike is also a section first violinist in the Columbia Orchestra and the Greenspring Valley Orchestra of Stevenson University. He has previously played in the Howard County Ballet Orchestra, the Chamber Orchestra of Mt. Vernon Place, and the Johnstown (PA) Symphony Orchestra.
