UMS Group Inc. was founded in 1989 by Jack Shearman. In 2007 UMS Group Inc. expanded its operations within Europe and moved the European office to Amsterdam, establishing UMS Group Europe. UMS Group was sold in late 2023, the European office was acquired by OHROS Energy Group and rebranded as OHROS Consulting Group B.V. Besides the office in The Netherlands, OHROS Consulting Group opened offices in Italy, Portugal and Spain.


Our team is driven by top-sport mentality and a collective commitment to go beyond the conventional. We believe teamwork is the foundation of success. Many of team members are high-level athletes in rugby, hockey and football, and the lessons learned on the sport field translate directly to how we work.
In sports, every position has a unique role and requires different talents, but all are equally important to win. “Alone we can do so little; together we can do so much.” The same principle applies within our organization. Every individual brings distinct skills and perspectives, and every role is essential to achieving project success for our clients. This dedication is not just what we do – it’s why we do it and who we are, as we stand alongside our clients, crafting legacies of enduring success.
Combined with our experienced staff we work with an eco-system of consultants, analysts, data scientists, programmers, and subject matter experts to respond to client engagements.
