I spoke with Father John Rickert, FSSP, today. He is the chaplain for Regina Pacis (the Latin Mass Community in Lexington, KY). He has tentatively agreed say the Traditional Latin Mass for the conference on Sat., June 4 at 8:00 A.M. Eastern time.
From the Regina Pacis website:
'The chaplain, Fr. John Rickert, FSSP, was ordained by Bishop Fabian Bruskewitz for the Priestly Fraternity of St. Peter on May 22, 2010, and Regina Pacis is his first assignment. A native of central Kansas, Fr. Rickert lived in the Dallas, Texas, area before entering the seminary. While in Texas he taught mathematics at the college level for two years and worked as an analyst for a benefits consulting firm for six years.'
