Meet Mergers & Acquisitions' 11 Rising Stars of Private Equity.

Ethan Liebermann led TA Associates’ investments in Aldevron and MedRisk and co-sponsored CCRM, Datix and SoftWriters. Jennifer Roach helped Yellow Wood Partners build PDC Brands and sell it to CVC Capital Partners. Liebermann and Roach are among 11 private equity investors identified as emerging leaders by Mergers & Acquisitions.

In choosing the Rising Stars of Private Equity, Mergers & Acquisitions sought full-time private equity investors whose best days are expected to be in the future. These are the folks predicted to one day play a key leadership role at their PE firm – or to be heading up their own firm. There was no specific criteria, but investing in middle-market companies and growing them had to be the focus of the candidates’ day-to-day activities. Promising candidates were likely recently promoted, or had recently launched a new endeavor. There was no age cut-off.

To help identify emerging leaders, we reached out to the industry and requested input from our readers through articles on our website,, and in our Daily Briefing e-newsletter. The nomination process was informal, and all decisions were made by our editorial team, headed by Editor-in-Chief Mary Kathleen Flynn. There was no fee and no limit on the number of individuals recommended. The deadline for nominations was June 8.

As we spoke with dealmakers about the 11 Rising Stars, common themes emerged. All have demonstrated the ability to handle many aspects of the PE business, including: fostering trusted relationships and developing deep networks throughout the sectors they invest in; forging and/or expanding their firm’s investments in key sectors; identifying add-on acquisitions and other opportunities for portfolio companies; representing their firms well in the marketplace; and taking on leadership roles within their firms, including developing new systems and tools and training other dealmakers.

Daniel Hopkin
Partner, Kainos Capital

“Dan proactively develops relationships,” says Kainos Capital managing partner Andrew Rosen, when asked to describe partner Daniel Hopkin’s role at the Dallas firm. “That’s what he did in the case of Kettle, and his skills have been instrumental in helping the company double in size since we purchased it.” Kainos bought Kettle Cuisine in 2015, and quickly developed a deep network within the refrigerated soup category, which led to two add-on acquisitions within the first year of Kainos’ ownership.

Kettle is just one of many investments Hopkin has worked on since he was one of the original team members when Kainos was spun out of HM Capital in 2012. He has also worked on: Bonewerks Culinarte’, Country Fresh, Fempro, InterHealth Nutraceuticals and Olde Thompson.

Hopkin received his B.A. in accounting and his Master of Professional Accountancy from Brigham Young University. He worked in the M&A department of Morgan Stanley and joined HM in 2004 as an associate and was quickly promoted to vice president. He made partner at Kainos in 2015.

“Dan’s work ethic and insights into the underlying drivers of a business are key,” says Rosen. “He has terrific instincts and a lot of runway ahead of him.”

John Kos
Principal, GTCR

It’s been a busy five years for John Kos, who has been spearheading GTCR’s foray into the healthcare information technology sector. Back in 2013, the firm had no healthcare IT companies in its portfolio. Today, the firm has four and has already enjoyed return of invested capital through some dividend recaps in the vertical.

Kos earned a BS in finance with highest honors from the University of Illinois. Early in his career, he worked as an analyst in the healthcare investment banking group of Citigroup Global Markets in New York. He first joined GTCR as an associate in back in 2006, then left to attend Harvard Business School, where he earned an MBA with distinction. He rejoined GTCR as a vice president in 2011. Since coming back to the Chicago firm, Kos has closed 33 M&A deals associated with 7 portfolio companies he acquired and/or oversees. He was promoted to principal in 2017.

One of the GTCR portfolio companies Kos nurtured is Cole-Parmer, a carve-out from Thermo Fisher,in a $480 million transaction in 2014. Under the firm’s ownership, Cole-Parmer, which makes test and measurement products for laboratory research, acquired six companies. It all added up to GTCR’s selling Cole-Palmer to Golden Gate Capital in 2017.

Erik Latterell
Director, Stone Arch Capital

Erik Latterell wears many hats at Stone Arch. His responsibilities include sourcing and reviewing new investment opportunities, negotiating transactions, leading financings, conducting due diligence, and working with various portfolio companies on add-on acquisitions and other strategic initiatives.

“We are a little different. We all do everything here,” says director Michael O’Neill. “Erik does a great job listening. He’s also smart, which makes him great at finding opportunities, but also seeing the challenges. He will then find the right people to help him tackle those challenges.”

Latterell first joined the Minneapolis firm as an analyst in 2007, and then rejoined in 2013 as a vice president, after graduating from the Carlson School of Management at the University of Minnesota. He was promoted to director in 2016. Prior to joining Stone Arch, Latterell was an analyst at the Minneapolis-based boutique investment bank TripleTree LLC.

At Stone Arch, Latterell has been involved with six of the private equity firm’s portfolio companies in a range of industries.

Jaime McKenzie
Managing Director, Monomoy Capital Partners

A freshly minted managing director, Jaime McKenzie has become a vital part of Monomoy Capital Partners. McKenzie has been involved in more deals than any other professional at the firm, reports Justin Hillenbrand, co-founder of the New York firm. She has worked on everything from a traditional leveraged buyout to a complex special purpose acquisition company (SPAC). She is also the first woman at the firm to be the chair of a portfolio company.

McKenzie has become a great ambassador of the firm, presenting to investors and at management meetings. “She articulates our message very well, and it became clear we could put her in front of any audience. At just 33, she already has so much experience, which is unique,” says Hillenbrand. “She is definitely a proven leader at the firm.”

McKenzie started at Monomoy as an analyst in 2008. In addition to her outward-facing responsibilities, McKenzie takes on training and developing vice presidents, associates and senior associates at the firm.

Shainberg started his career as an investment banker with JP Morgan and then moved to Brookfield Asset Management before joining Balmoral as a senior associate in 2012.

Shainberg has increasingly sought and excelled at transaction due diligence and arranging debt financing. In the second quarter of 2018, Shainberg ran his first deal, purchasing burger chain Mooyah. He led all aspects of the deal, including due diligence and execution, front to back, stepping into board level roles, expanding business development capabilities, growing his network, and working closely with operating advisors, CEOs and industry consultants.

“David has been looking to take more of a leadership role, and it happened on this deal,” says Balmoral managing director Robin Nourmand. “Before leading this deal, he had been putting pieces of deals together, but he took the reins on this, and he did a good job soliciting feedback from us, negotiating on all points and serving as a liaison between the operating advisors and everyone else.” Today, Shainberg is responsible for finding and vetting all potential deals in the restaurant sector.

Vice President, Shore Capital Partners

Nicholas Stone
Managing Director, Cyprium Partners

In early 2017, Nicholas Stone was promoted to managing director. He leads the firm’s deal origination efforts and oversees the Chicago office. “There’s a lot of capital out there,” says managing partner Mike Conaton. “We distinguish ourselves by building a rapport with management teams. Nick is incredibly talented at doing that. There’s a trust factor he establishes with people early on, and it helps us win deals. He is able to really resonate with folks, which is critical in our business,” says Conaton. Stone’s background of growing up on a farm in Nebraska may be one reason Stone appreciates hard work and loyalty, Conaton suggests.

When Stone is not on the hunt for new deals, he is managing Cyprium’s six operating partners who help the firm evaluate various investment opportunities. Although working with very experienced professionals, Stone is able to keep them engaged and involved in every process.

Stone was a member of the investment team previously known as Key Principal Partners, which became Cyprium in 2011. Before joining KPP in 2007, he worked at Northlight Capital. He holds an MBA from the University of Chicago Booth School of Business.

She is a strong member of our team and we have high expectations for her.”
