John Grogan

In the spring of 2012, he joined Lehigh University as an adjunct professor in the department of journalism and communication. He teaches a writing course called Memoir and Me: First-Person Non-Fiction Narratives.

In 2007, he began working full-time on his new book, a memoir, The Longest Trip Home. It was released on October 21, 2008. The Longest Trip Home is a coming of age memoir about Grogan's relationship with his family, particularly with his parents, revolving around the theme of "powerful love of family." According to his website, it is "a book for any son or daughter who has sought to forge an identity at odds with their parents', and for every parent who has struggled to understand the values of their children."

In 2004, Grogan began writing Marley & Me, which is told in first-person narrative. Marley is a yellow Labrador retriever, boisterous, somewhat uncontrolled, powerful and often destructive of property but loyal and loving and always forgiven. Released in 2005, Marley & Me was an international bestseller, having sold over five million copies in over thirty languages. It spent 76 weeks on the bestseller list, and 23 of those weeks it stood at the #1 spot. His first book earned him Quill Awards in the Audiobook and Memoir/Biography categories in 2006. It was later adapted into a film that was released on December 25, 2008, starring Owen Wilson as Grogan.

In 2003, when Grogan's dog, Marley, died at age thirteen, Grogan wrote a column in The Philadelphia Inquirer honoring him, and he received over 800 responses from his readers. The readers' astounding response and interest in Marley sparked Grogan's decision to write a book, due to the realization that he had "a bigger story to tell" and "owed it to Marley to tell the rest of the story."

He met his future wife, Jenny Vogt, while working at the Herald-Palladium, where she was also a reporter on the staff. They married on September 2, 1989 at Our Lady of Refuge Church, Orchard Lake Village, Michigan.

His first college internship was at a community weekly paper called The Spinal Column. Upon graduation from Central Michigan University in 1979, he was hired as a police reporter for the St. Joseph Herald-Palladium. In 1985, he received a fellowship into the Kiplinger Mid-Career Program in Public Affairs Reporting at Ohio State University, where he earned a Master's degree in Journalism, graduating in 1986. He was later accepted as a fellow at the Poynter Institute of Media Studies in St. Petersburg, Florida. After the fellowship, he was hired as a bureau reporter at the South Florida Sun-Sentinel in Fort Lauderdale, eventually being promoted to metropolitan columnist. In 1999, he was named managing editor of Rodale's Organic Gardening magazine and moved to Pennsylvania. Three years later, in 2002, he joined The Philadelphia Inquirer as a columnist. The Inquirer published a volume of his best articles in 2007 called Bad Dogs Have More Fun.

Grogan notes that his mother's passion and gift for storytelling "wore off" on him. By eighth grade (1970–71) at the Our Lady of Refuge, he was writing humorous stories about the nuns. He transferred from the Brother Rice Catholic High to a public high school, West Bloomfield High School (class of 1975), as a sophomore. He wrote for his school newspaper in high school and started an underground tabloid.
