According to Luke Ford - Aron Tendler No Longer A Rabbi

(Aron Tendler is the younger brother to Mordecai Tendler)

Aron Tendler Says He's No Longer A Rabbi

Aron Tendler sent out a single-page letter (which hit mailboxes July 10, 2006) to all the members of Shaarey Zedek, where he served as a rabbi for about eight years until he resigned earlier this year over charges of sexual misconduct, announcing that he was no longer a rabbi in any capacity and should not be asked to decide halakhic questions or to do marital therapy.

Aron has numerous supporters at Shaarey Zedek who've continued to treat him as a rabbi over the past few months.
