New York, NY/Santa Monica, CA (May 28, 2013) – MTV President of Programming Susanne Daniels today announced that Lauren Dolgen has been promoted to Head of West Coast Reality Programming, Executive Vice President of Series Development for MTV. Her previous title had been Head of West Coast Reality, SVP Series Development. In her expanded new position, Dolgen will oversee the strategic creation and development of all of the network’s west coast based reality television slate, including oversight of such current hits as “Teen Mom 2,” and “Ridiculousness,” the upcoming “Teen Mom 3,” as well as adding on the next season of “The Real World” to her responsibilities, among others. Based in Santa Monica, she will continue to report to Susanne Daniels.

“I have worked with many talented television executives but Lauren’s ability to tap into such a vast array of characters, formats and narratives is truly extraordinary,” said Daniels. “From mining the antics of a group of hysterical pranksters with “Jackass,” to producing one of the most exciting music and dance competition shows with “Randy Jackson Presents: America’s Best Dance Crew,” to developing the honest, bittersweet stories of teenagers navigating parenthood in “Teen Mom 2,” Lauren’s influence can be felt across MTV.” Daniels added, “Her sensibility resonates with our audience with just the right blend of outrageousness and heart. Producers love to work with her and I’m very much looking forward to working with her in this new role.”

During her more than 16-year tenure at MTV, Dolgen has played integral roles in the production, development and creation of a number of top-rated series and specials. In 2009, she created and developed the groundbreaking docu-series “16 and Pregnant,” which captivated millions of viewers with its honest depiction of the lives of pregnant teens. The follow-up series, “Teen Mom,” and “Teen Mom 2” resonated strongly with viewers, with the most recent season of “Teen Mom 2” drawing in an average 3.4 million viewers (Live+3) each week. “Teen Mom 2” is also one of the top cables series of 2013, with last season ranking as Monday’s #1 cable series. Critics and the media have hailed the franchise for acting as one of the best safe sex PSAs ever, and experts have cited it as contributing to the recent decline in teen birth rates.

Earlier this year, Dolgen and her team developed “BUCKWILD” for MTV, capturing the hearts of viewers and ranking as Thursday’s #1 cable series during its run. She has also been involved in the production, development and creation of such well known MTV series as “Ridiculousness,” “Jackass,” “Randy Jackson Presents: America’s Best Dance Crew,” “Rob Dyrdek’s Fantasy Factory,” “Rob and Big,” “Viva La Bam,” and more. The most recent season of “Ridiculousness” was also Thursday’s #1 cables series during its run, and – over eight high-energy seasons, “Randy Jackson Presents: America’s Best Dance Crew,” averaged an impressive 2.3 million viewers (Live +3) per week.

A lifelong TV junkie, Dolgen joined MTV immediately after graduating from college, following a successful internship abroad in the communications department at MTV UK in London. Her first official position within Viacom was in 1997, when she was hired as a Production Associate on “Behind the Music” for VH1. She moved to MTV in 1998 where she became a Production Coordinator. In 1999 she shifted from production to development, where she quickly moved up through the ranks. Most recently, she acted as Senior Vice President of Series Development for MTV, West Coast. Born in New York, Dolgen grew up in Los Angeles and holds a Bachelor of Arts degree from Pitzer College.

In addition, Daniels announced that Kimberly Rach and Andrew Portnoy will now co-head production for MTV. Portnoy, Senior Vice President and Co-Head of Production for MTV, is based in New York and Rach, Senior Vice President and Co-Head of Production for MTV is based in Santa Monica. The two will split east/west coast production responsibilities for all of MTV’s programming including scripted, reality, pilots and specials. Both will now report to Daniels.

In announcing Portnoy’s and Rach’s new roles, Daniels said “Andy and Kimberly have been integral in running one of the most aggressive television production slates in television.” She added, “They make a great team and are well poised to lead MTV’s productions moving forward as we continue to build MTV’s eclectic programming schedule.”
