Leadership Commentary
“This union is a transformative step forward, combining the strengths of two industry leaders,” said Carmen Castillo, President Emeritus of SDI International. “The synergy between our companies is immediately beneficial for our clients,” added Allison McCrea, Managing Director of HCMWorks. “By unifying our capabilities, we will empower organizations to transform how they manage strategic and non-strategic spend, unlocking previously unattainable savings and strategic opportunities.”
Looking Ahead
The merger enhances both organizations’ ability to serve key industries – including pharmaceutical, healthcare, technology, and banking/finance – while opening new pathways for innovation and client growth.
HCMWorks will adopt the SDI brand in the coming months, with Allison McCrea leading the combined company as CEO. Carmen Castillo will assume the role of Strategic Advisor. Clients and partners can expect full continuity of service throughout the transition, along with access to new capabilities and expertise.
