Welker was the launch publisher for the magazine when it started regular six-times-a-year publication in early 2014. She is stepping down at the end of the year.

The decision to leave Dr Oz. The Good Life was Welker’s. She plans to spend time with her family and volunteer with the Muscular Dystrophy Association.

Before becoming launch publisher of Dr Oz. The Good Life, Welker was the founding publisher of Cosmo Girl!, from 1999 to 2008. She then built the early digital sales and marketing organization for Hearst Magazines, from 2008 to 2013.

Seelig was senior vice president, corporate development at Hearst since leaving O, The Oprah Magazine, as former publisher and chief revenue officer in October 2014.

Previously, Seelig was advertising director at Vanity Fair, and before that, beauty director at Self. She began her publishing career at New York.

As Publishers Daily previously reported,  Dr. Oz The Good Life launched its online site this September.

Led by Sarah McNaughton, previously a senior editor at Everyday Health, the site features content about the core topics explored in the magazine, including healthy recipes, natural beauty, balanced diet and fitness plans.

The print edition of Dr. Oz the Good Life debuted last year with a rate base of 450,000. This year, it moved to a schedule of 10 issues annually, while the rate base increased to 800,000 in July 2015.

Dr. Oz, a peppy and sometimes controversial heart surgeon and TV personality, has said he hopes the magazine eventually reaches 2 million readers.
