Eschenbach and Leer to Manage New Divisions

We are pleased to announce that Alex Eschenbach will serve as division administrator for the Divisions of Pulmonary & Critical Care Medicine and Allergy & Clinical Immunology and Jonathan Leer will take on the Division of Hematology effective Jan. 2.

Alex Eschenbach, MBA, earned a bachelor’s degree in microbiology and immunology from the University of Texas-Austin and a master’s of business administration with a concentration in healthcare administration, data analytics and marketing from the JHU Carey Business School. Before pursing his master’s, he worked as a software training specialist for the electronic medical record company eClinicalWorks as well as administrative director of a small international high school in Guatemala. In 2018, Alex moved to Baltimore and served as senior administrative manager of the Division of Allergy & Clinical Immunology. After two years in that role, he became the assistant administrator of the Division of Hospital Medicine at JHBMC and the newly-formed Division of Hospital Medicine at JHH where he managed the COVID-19 Staffing Office and navigated the challenges of overseeing two highly clinical divisions during a global pandemic. We are excited for Alex to return to his Hopkins roots in the Division of Allergy & Clinical Immunology and confident in his ability to lead the Division of Pulmonary & Critical Care.

Jonathan K. Leer, MHA, FHFMA, FACMPE, is originally from Fort Smith, Arkansas, and moved to Texas to earn a bachelor’s degree in business administration from Texas Christian University. He then earned two master’s degrees in accounting and healthcare administration from the University of Texas at Arlington where he is an adjunct professor teaching healthcare finance and accounting in the MHA program. Prior to joining Hopkins, he worked at UT Southwestern Medical Center for the Department of Pediatrics in multiple management roles. Jonathan is a fellow of the Healthcare Financial Management Association and the American College of Medical Practice Executives, an active member of the American College of Healthcare Executives and has spoken at numerous national conferences on the topic of physician management and education of business concepts to healthcare providers. In 2022, he joined the Department of Medicine as administrator of the Division of Geriatric Medicine & Gerontology where he will remain division administrator in addition to his new role as division administrator of the Division of Hematology. We are confident Jonathan’s experience in the DOM will serve him well in his expanded role.

We’re very excited for Alex, Jonathan and their respective divisions, and ask you to join us in welcoming them to their new roles.
