Steve Harrison has named Greg Collett as his new campaign manager.

Greg Collett, a graduate of George Washington University Law School, recently stepped down as a director at Deutsche Bank, where he developed and managed the bank's exchange traded commodity fund business.

Before his work at Deutsche Bank, Collett had experience as a legislative aide to a New Jersey state senator and on various campaigns.

Collett had previously been involved with Harrison's campaign in a fundraising capacity.

Also, longtime Harrison volunteer David Hernandez, a Staten Island resident and a member of the Richmond County Democratic Committee, is the campaign's new field coordinator.
