Meet Our Professional Team

Interim Administrator

Bree Keer is an English Major having attended Russell Sage College Evening Division, SUNY Albany, and Empire State College when she could take classes. She has been an office administrator for over 30 years, having spent 17 years with The American Legion, NYS Headquarters office; and 11 years with Ways and Means Majority of the NYS Assembly (concurrent jobs).  She has worked for non-profits her entire working career and has worked with victims of domestic violence and abuse and Veterans (beyond what she did with The American Legion).  She also promotes agencies and organizations that work for the LBGTQIA community and against sex trafficking.

Bree was raised in both her mother’s Mennonite faith and her father’s Scot’s Presbyterian faith.  Her family instilled in her a strong commitment to service and the firm belief that all people are created equal, and that everyone is free to be who they are, celebrate who they are, and worship how they choose. Bree is a widow.  Prior to marrying her late husband, she was a single mother who raised 3 children on her own which explains why she can multi-task so well.  She has 2 sons, 1 daughter, 8 granddaughters, 1 granddaughter-in-law, 3 grandsons, 3 grandsons-in-law, 2 honorary grandsons, 2 great-granddaughters, 2 great-grandsons, and number 5 great-grandchild (tie-breaker) is due in November.  5 of Bree’s children and grandchildren are currently serving in the US military or are Veterans. Also, her grandson is engaged to be married in Fall 2023!
