[2][3] His father Benjamin Bloom is an ophthalmologist, and his mother Esther Stern-Bloom is a retired Hebrew and French teacher.
[6][4] In 2004, Bloom received a bachelor's degree in Latin Classics from Yale College, where he was a member of The Society of Orpheus and Bacchus.
[2] He was promoted to assistant director of Minor League Operations in 2008, with responsibility for all aspects of the team's minor league system, including player evaluation and assignments, expansion of video, strength and conditioning, and mental skills initiatives, creating of the "Rays Way" player development manual, and executing individual development plans for organization's prospects.
[10][2][11] He was named Director of Baseball Operations in 2011, expanding his job to include contract negotiations, salary arbitration, budgeting, and overseeing major league support staff and international scouting.
[12][13] His responsibilities expanded to include his overseeing domestic and international player development, a newly created baseball performance science department, trade negotiations, pro, amateur, and international scouting philosophy, personnel additions and changes throughout baseball operations, and short- and long-term strategic planning.
He was an early user of breakthrough strategies, now more widely used, such as a much heavier emphasis on shifts and the use of openers (starting games with relief pitchers).
[23][24] Since the Red Sox were trying to reduce salary and get under the luxury tax threshold for the 2020 season and in the future, Bloom was hired because of his experience at managing a low payroll on the Rays.
Bloom subsequently hired Alex Cora to return as the team's manager after fulfilling his suspension, announced in November 2020.
