Junko is an operator-investor with more than 25 years of experience across healthcare and TMT, combining hands-on leadership of high-growth companies with a strong investment, M&A and capital raising background.
As founder and CEO of UNAVETS, she scaled an ambitious buy-and-build strategy into the leading veterinary services platform in Spain over five years. She also acquired and grew OneVet, building it into the leading veterinary services platform in Portugal.
In parallel, Junko played key roles in building other category leaders across Europe in the veterinary sector. She served as a Board Director and turnaround advisor for Oaktree Capital on Luxvet Group, helping to transform it into the leading veterinary services platform in Central and Eastern Europe, and as a Board Director of BSA, guiding it to become the leading veterinary blood bank in Europe. Following her exits from UNAVETS and Luxvet, she acted as a Senior Advisor to Oaktree Capital, supporting their healthcare services and buy-and-build initiatives, before relaunching Marconi Capital.
Junko has also served as an Advisor to the James Cameron Group and other institutional clients, and built a strong foundation in investment banking, where she advised on more than $30 billion of TMT capital raising and M&A transactions, with a particular focus on media and technology businesses.
Junko also serves as a Trustee to the African Wildlife Foundation UK Board and as a Trustee for the Cheam School Foundation, which provides life-changing bursaries to children.
She holds a BA from UC San Diego and an MBA in Finance from the Wharton School.

“Junko’s unwavering commitment to building a business founded on principles yielded unprecedented growth and, moreover, a dedicated, happy and collaborative team highly motivated to succeed. She delivered extraordinary results but achieved them in a way that never varied from the ethics and humanity too often forgotten in the sole focus on ROI.”

Co-Chair of the Cameron Group

“Because of my role, I have exposure to different management teams doing buy and builds. I can confirm Junko ranks extremely high compared to others. She is probably one of the best managers I have met for a buy and build situation.”
