Jeff Greenstein


Jeff Greenstein’s passion for investing, trading, and collecting began over 4 decades ago with sports cards. The past 15 years these energies, or arguably obsessions, have been channeled into contemporary art. The Greensteins’ constantly-evolving interests and holdings arise from Jeff devoting significant time to studying from an extensive art book library, regularly visiting art fairs and galleries, and speaking with knowledgeable collectors, curators and dealers. Jeff finds the quest to identify, learn about and then source undiscovered and potentially important works to be intellectually stimulating, personally rewarding and a ton of fun. 

Jeff is also the Co-Founder, Chairman and Interim CEO at 98point6. 98point6 is pioneering a new approach to primary care by pairing deep technology with the expertise of board-certified physicians. Their innovative service offers consistent access to comprehensive care in sickness and in health, and includes diagnosis, treatment, prescriptions and labs as well as consultation for any health-related question. 98point6 provides accessible care with uncompromising quality—all at a massively lower cost than anything else on the market today.
