Analysis

London – August 4, 2025 – Advent International, one of the world’s leading private equity investors, has appointed Robert Ohrenstein as an Operations Advisor focused on finance. With over 30 years of experience in global financial services, Ohrenstein will play a strategic role in guiding Advent’s portfolio companies through financial transformation and transaction execution.

Previously the Global Head of Private Equity at KPMG, Ohrenstein also served as a UK Vice Chair where he led a $1 billion investment strategy aimed at expanding KPMG’s private equity relationships—including its longstanding ties with Advent. His leadership at KPMG spanned nearly a decade and shaped how the firm partnered with global investment managers to support growth through financial engineering and strategic advisory.

Ohrenstein’s appointment strengthens Advent’s efforts to enhance operational value across its portfolio, a key priority as the firm continues deploying capital across its core sectors: business & financial services, consumer, healthcare, industrial, and technology.

“Robert brings unmatched insight and credibility from his work advising private equity firms and management teams around the world,” said Selim Loukil, Managing Director and Head of Advent’s Portfolio Support Group (PSG) in Europe. “We’re confident his partnership approach and deep understanding of the financial ecosystem will accelerate our companies’ growth journeys.”

Before joining KPMG, Ohrenstein was a partner in the Private Equity Group at Deloitte and began his career at Andersen. His academic background includes an MBA from the University of Warwick and a BSc (Econ) from the London School of Economics. He is a Fellow of the Institute of Chartered Accountants in England and Wales.

Strengthening Operational Value in a Competitive Market

This strategic appointment comes at a time when private equity firms are increasingly focused on value creation amid a more complex dealmaking environment. Advisors like Ohrenstein are critical to helping PE firms optimize portfolio performance without relying solely on leverage or market timing.

Advent’s use of Operations Advisors and Operating Partners reflects a broader trend across the private equity landscape where hands-on support and functional expertise have become essential to delivering returns. Firms such as TPG, EQT, and KKR have similarly expanded their value creation teams in recent months.

“I’m honored to join Advent and contribute to its mission of driving sustainable value across global investments,” said Ohrenstein. “My goal is to bring financial discipline, strategic insight, and executional rigor to help management teams achieve transformative growth.”

Advent currently manages over $94 billion in assets across 44 countries, having completed more than 430 investments since its founding in 1984. With a team of 660 professionals across 16 global offices, the firm continues to reinforce its commitment to building industry leaders through collaborative partnerships and operational excellence.
