Gregg Michaelson, the integrated marketing president and chief marketing office with Rodale, has left the company. Michaelson was with the publisher since 2001, beginning his tenure with Rodale’s book division.

According to Adweek, Michaelson’s departure follows the exit of former Rodale COO and CIO Ken Citron in late September. A source tells FOLIO: that Michaelson left the company to focus on developing digital businesses, and no replacement has been named.

In a board meeting today, Rodale CEO (and company founder J. I. Rodale’s granddaughter) Maria Rodale discussed the future of the publisher as “a media and lifestyle company”. Adweek cites a company email in which Rodale wrote that she would expand on a strategy further within coming weeks.

Other changes at Rodale include the recent naming of Laura Frerer-Schmidt as publisher of Women’s Health. Frerer-Schmidt joined Women’s Health from Self (where she was associate publisher) on September 6.
