Our Team
Jochem Overbosch
Founder and Managing Partner
Jochem Overbosch brings a unique blend of personal resilience, global perspective, and strategic expertise to his role as Founder and Managing Partner of Overbosch & Co, an executive search firm specializing in healthcare leadership. His journey reflects a lifelong commitment to excellence, purpose-driven work, and building trusted relationships across sectors.
Jochem began his journey at the University of St. Gallen in Switzerland, where he developed a foundation in business and leadership. Early roles at Deutsche Bank and Booz Allen Hamilton provided him with extensive international experience, honing his analytical skills and igniting his passion for solving complex challenges. It was through these experiences that Jochem identified his calling in executive search, particularly within the healthcare sector—a field marked by its complexity, societal impact, and the extraordinary dedication of its professionals.
This focus became deeply personal when Jochem served as a non-executive Chair for a small healthcare provider. This role underscored the transformative power of (medical) leadership in driving both quality and accessibility in healthcare delivery. This realization became the cornerstone of his career, inspiring him to pursue impactful leadership solutions within the sector.
For over 15 years, Jochem led the healthcare practice at Odgers Berndtson, where he cultivated deep relationships across Europe and contributed to transformative initiatives within the industry. Driven by a desire to make an even greater impact, he founded Overbosch & Co in 2024. The firm is dedicated to partnering with organizations to identify and place visionary leaders who align with their strategic objectives and can catalyze meaningful change.
Jochem is recognized for his strategic acumen, industry expertise, and unwavering commitment to integrity. Under his leadership, Overbosch & Co aims to play a pivotal role in shaping the future of healthcare by strengthening the leadership structures that drive innovation and progress.
Jochem lives just north of Amsterdam with his wife and two daughters.

Thomas Coenen
Consultant
Thomas Coenen is Overbosch & Co’s most recent addition. His exceptional curiosity and analytical skills enable him to quickly understand complex organisational challenges and their broader context, and to identify how people can be part of the solution in navigating them.
Thomas began the academic part of his journey at Erasmus University Rotterdam and later continued his studies at the Korea Advanced Institute of Science and Technology (KAIST) and the University of Groningen, focusing on International Business & Management and International Economics.
While writing his master’s thesis, Thomas somewhat stumbled upon healthcare. He was struck by the parallels between international banking and finance and the transformation of the Dutch healthcare system - similarities that proved both unexpected and compelling.
His career has taken him through several boutique consulting firms and one larger firm - PwC / Strategy, the successor to Booz & Company - and has given him the opportunity to work with a substantial number of hospitals (nearing 30) and multiple health insurers, both in the Netherlands and internationally.
He is particularly driven by the challenge of helping healthcare evolve towards a much more future-proof model, preserving access to high-quality care for generations to come.
Thomas lives in Hattem, Gelderland, a small town near Zwolle, with his wife, a dermatologist MD at Isala, and their two daughters.
