After over two-decades in the entertainment industry, Jansen has built a solid reputation as an effective and well-respected personal manager and communications professional. Beginning at 23 years of age, Jansen was not only one of the youngest nightclub owners in the country, he also boasted one of the premier live music venues in Chicago: Avalon Nite Club. Through the Avalon, he booked and promoted sold-out concerts with major national touring acts like Stone Temple Pilots, White Zombie, Crash Test Dummies, EMF, L7, Hole, and many more. Being the first major club to promote groundbreaking urban shows like DeLa Soul, The Brand New Heavies and Sir Mix-A-lot, the Avalon Nite Club became known across the country, and a regular stop for national tours. He also produced live theatre and musicals. 

Having built a solid relationship with these touring acts and their agents as well as the major label A&R community, Jansen went on to launch KMA Management in 1996. Shortly after founding KMA Management and solidifying his presence in the industry on a national level, Jansen was handpicked by Warner Bros. Records to act as a regional A&R Representative, while simultaneously building up his company and reputation. 

The following year, he also founded the annual music conference: MOBfest. As founder and director of the nationally recognized Chicago music festival MOBfest, Jansen has driven the annual event to become the biggest and most successful music business seminar in Chicago’s history. For over fifteen years, MOBfest was a launching pad for emerging acts like Disturbed, The Killers, Kill Hannah, Rachael Yamagata and the Assassins. 

Over the years, Jansen, and KMA Management, has closed multiple major record label and publishing deals; Disturbed (Reprise) sold over 4.5 million records, and the Riddlin Kids (Columbia) sold over 100,000 records independently of the label by utilizing touring and street marketing strategies implemented by KMA Management. Other signings include, Dovetail Joint to Columbia Records, From Zero to Arista Records, Absentstar to RCA Records, Extra Very to Warner Bros. Records and the Blank Theory to New Line Records. Having worked with major publishers over the years, Jansen honed-in his skills in music placement, film / TV synch licenses, and master usage licenses. In 2010, Jansen was brought on board by Red Bull as an A&R consultant, as the worldwide brand launched their label, Red Bull Records.
