Executive search firm ZRG Partners Inc. acquired certain assets of HM Long Global Partners, bolstering its global life sciences executive search practice.

The transaction closed July 5; terms were not disclosed.

As part of the asset acquisition agreement, Helga Long, formerly the chair and CEO of HM Long/RSVP Group, is joining ZRG Partners. She will remain as the CEO of HM Long Global, a division of ZRG Partners, and will assume the role of chief client officer in ZRG’s global life sciences practice following the integration of the assets. Long has 30 years of experience with senior-level talent acquisition. Prior to the merger of HM Long Global Partners and RSVP, Long spent 10 years with another global search firm as a vice chairman of the firm’s life sciences practice.

“Our current life sciences team, led by Adam El Din, as global practice head and David Fortier, North American leader, have delivered amazing results the past few years,” said ZRG Partners CEO Larry Hartmann. “The addition of Helga Long and the team creates the most powerful super-boutique solution for life sciences clients globally. We could not be more excited about the addition of the entire team that has worked together in the market for years.”

Others joining ZRG Partners include Charles Rohaut, managing director in France; Derick Haire, senior client partner in Texas; and Lydia Coleman in Virginia.

Headquartered in New York, with branch offices in Austin, Texas, and Paris, France, HM Long/RSVP Group counts approximately $4 million in annual revenue. The business, through its various ownership structures, has completed more than $35 million in senior-level executive search work worldwide during the past 10 years.

ZRG’s global headquarters is in Rochelle Park, NJ. The multipractice global search firm targeted sectors include life sciences, industrial, financial services, consumer, private equity and technology.
