Sullivan said he could "offer no justification or explanation" for ignoring phone calls from White and his family.
The Supreme Court has admonished Sullivan on five occasions for similar conduct, the order states. In one of the most recent instances, Sullivan promised the Lawyer Disciplinary Board that he would be "more diligent in representing his clients.
"However, the record shows that at the same time he was making this pledge, the Respondent was ignoring repeated requests from Mr. White and Mr. White's family to take that action necessary to correct a facially inaccurate sentencing order," the order states.
Kanawha County Chief Public Defender George Castelle said Sullivan will serve his 30-day suspension in a "non-lawyer capacity.
"We expect him to successfully complete the terms of his suspension and return to an active, supervised practice," Castelle said Wednesday. "His cases have been assigned to other lawyers in the office."
Castelle said Sullivan will remain in the Public Defender's Officer after he completes the suspension. He would not comment on Sullivan's performance.
"I'm really not able to say more," Castelle said, "other than to identify his current status."
