17th Jun 2026 09:18

(Sharecast News) - Tristel announced the appointment of Christopher Lee as its chief executive officer on Wednesday, effective 1 August, following a competitive selection process.

The AIM-traded infection prevention products maker said Lee would replace Matt Sassone, who is leaving on 30 June to take a worldwide president role with a large US multinational.

Chief financial officer Anna Wasyl will act as interim CEO until Lee joins.

Lee was most recently chief executive of Summit Medical from 2020 to 2025 and previously led Venner Medical International.

Chair Bruno Holthof said Lee's medical technology experience, "especially in the US", made him "the ideal person to lead the business" as Tristel pursues further overseas growth.

At 0937 BST, shares in Tristel were down 1.1% at 380.75p.
