Dr. Jack Collier and Hazen Marshall will be the two newest members of the Hennessey Hall of Fame.

The pair will be inducted during the HHS graduation ceremony, which is 7 p.m. Friday, May 17, at the Eagle Event Center.

The HHS graduating class selects two candidates for induction each year.

The candidates are from nominations submitted this year or are carried over from previous years.

The HHS Hall of Fame was designed to honor HHS graduates and/or educators “who have excelled in a career, contributed to society and serve as an inspiration to students, alumni and community.”

Collier attended Hennessy Public Schools from kindergarten through 12th grade, graduating in 1989.

He earned a bachelor of science degree with distinction in psychology from the University of Oklahoma.

Collier was recognized as the Outstanding Psychology Student, was president of the Alpha Lambda Delta Honor Society and Chairman of Crimson Club.

He was awarded Top Ten Freshmen, Big Man on Campus and was a homecoming king finalist.

After earning his bachelor’s degree, Collier attended the University of Oklahoma College of Medicine.

He and two colleagues created the first online educational website for the medical school.

Collier served as the president of his class and later president of the medical school student body.

His class voted him the Podalarian Award winner.

After graduating medical school, Collier did his internal medicine residency at the University of Arkansas.

He was recognized as the Outstanding Intern of his class and later served as Internal Medicine chief resident.

He completed his cardiology fellowship at Saint Louis University and received the Academic Achievement Award.

Collier returned to OU for his electrophysiology fellowship. Upon completion of the program, Collier got his first official job as an electrophysiology attending at Saint Louis University, a mere 16 years after graduating high school.

Collier moved back to Oklahoma and practices at the Oklahoma Heart Hospital where he has served on that hospital’s board.

He has been active in clinical research, including a publication in the esteemed New England Journal of Medicine.

Collier said his most important accomplishment is his marriage to fellow medical student and best friend, Dr. Susannah Lambird Collier.

They have been married for 26 years and have three children: Ford, Price and Coffey.

Despite his achievements, Collier said his favorite titles are husband, dad and coach.

Marshall is a 1983 graduate of HHS and a 1987 graduate of Oklahoma State University.

Marshall is one of Washington, D.C.’s top policy experts, with three decades of legislative policy experience, including over 20 years in the Senate as a senior leadership aide and 15 years providing strategic consulting and lobbying services to Fortune 100 businesses and trade associations.

Following graduation, Hazen moved to Washington, D.C., where he began his career working for Senator Don Nickles (R-OK) from 1987 to 2004, including as staff director for the Senate Budget Committee and chief of staff to the assistant Republican leader.

During that period, Marshall worked on most of the major budget, tax and economic policies of the era.

When Senator Nickles retired, Marshall became a founding partner of the Nickles Group, where he spent a decade advising clients in a number of sectors, including energy, taxes, telecommunications, insurance, defense/aerospace and the automotive industry.

In 2015, Marshall returned to the Senate as the policy director for Senate Majority Leader Mitch McConnell (R-KY), a role in which he participated in the planning and execution of all Senate Republican legislative and political strategies.

Highlights of this period of service, he said, included the enactment of historic tax reform and confirming a conservative majority on the Supreme Court.

In 2019, Marshall retired from the Senate and is currently working as a founding partner of the consulting and lobbying firm Marshall & Popp.
