Jay Mazelsky is the CEO of IDEXX Laboratories, a leading company in veterinary diagnostics. Born in 1965, he earned his B.S. in Business Administration from the University of Massachusetts and his M.B.A. from the University of Michigan. He has had a notable career in business, having served in various leadership roles within IDEXX since 2018, including President and Interim CEO. Under his leadership, IDEXX saw significant growth, but he did not receive performance bonuses in 2022, highlighting the challenges faced in delivering results despite a strong overall compensation package of nearly $10 million that year. What’s really interesting is his pattern in stock trading; his holdings fluctuated dramatically, with his net worth reflecting the performance of IDEXX’s stock. At one point, in June 2021, his holdings peaked at approximately $37 million, showing a strong alignment with the fortunes of the company he leads. Although not without challenges, Mazelsky's ability to navigate the pressures of executive leadership in a vital industry sets him apart.
