Through his father, an aeronautical engineer and former U.S. Armed Forces member who worked at the Grumman Aerospace Corporation, he was exposed to science, mathematics, and engineering at a young age. This would greatly shape his creative outlook and desire to pursue knowledge in those fields.

Launching his career at AT&T Bell Labs, Mr. Hollar excelled as a project manager of the technical staff from 1992 to 1997 and subsequently served as a systems analyst at Deutsche Bank. Following a year as an intern with A.T. Kearney Consulting, he shifted focus to health care after his uncle succumbed to cancer and, he said, “the medical system appeared powerless to intervene.” This would inspire his later pursuit of telemedicine and remote patient monitoring, driven by the belief that proactive healthcare intervention is crucial.

Mr. Hollar was active as a senior manager at Pfizer from 2001 to 2008, co-founded TeleMed Innovations, served as the Chief Product Officer at NavaFit Inc., and led as the Director of Product Management with the New York eHealth Collaborative. In 2016, he joined the Mount Sinai Health System, working as the Director of Digital Health for eight years and has been the Senior Product Owner for Digital Product Delivery since 2024. His work there, particularly his focus on the intersection of remote patient monitoring and device-based digital health, has been recognized in publications and greatly valued by patients. On one such occasion, a patient remarked on feeling supported and cared for due to the monitoring program. This sentiment, for him, encapsulates the realization of a long-held aspiration.

In addition to these positions, Mr. Hollar has been active since 2015 as an adjust professor at the Columbia University Mailman School of Public Health, where he teaches both in-person and remote health innovation and technology classes. He’s also been active in the last three years as a panelist, speaker, and author of articles in the healthcare field. He prepared for his professional journey with a Bachelor of Science in computer science from Stony Brook University and a Master of Science in computer science from Columbia University. Amid his career, he bolstered his credentials with a Master of Public Health in health policy and management from the Mailman School of Public Health in 2008.
