WPP is combining its health agencies, Sudler & Hennessey, Ogilvy CommonHealth, and ghg with three respective full-service marketing agencies as it retires the WPP Health & Wellness brand.

Sudler will be combined with the newly formed VMLY&R, creating the VMLY&R Health practice; Ogilvy CommonHealth will join Ogilvy; and ghg will merge with Wunderman, becoming part of Wunderman Health, according to WPP’s statement.

The holding company expects to finish integrating the firms in the first half of next year.

The WPP Health & Wellness group will become a specialty health practice within WPP without its former branding. Global CEO Mike Hudnall will continue to lead the unit. Claire Gillis, current CEO of WPP Health & Wellness International, will continue to lead the international health business.

WPP formed the Health & Wellness sub-holding company in February 2017, separing these health-focused agencies into a different group. In Q2 2018, the business group that includes the health and wellness brands, along with brand consulting, and specialist communications, saw a revenue increase of 2.2% over the previous year. WPP is set to release its Q3 earnings report tomorrow.

WPP named Mark Read, former Wunderman chief executive, as CEO in September, five months after Martin Sorrell stepped down from the role. Last month, WPP also merged VML and Y&R to create digital brand experience agency VMLY&R.
