In 1999, Ronnie relocated to the the State of Washington and chose to step away from sports management & dedicate his attentions to developing his mediation practice. In Washington, he was fortunate enough to forge solid friendships with a number of Washington State Superior Court Judges who advised him and guided him in his quest to become an effective mediator. At their urging, Ronnie founded Sound Mediation which he then renamed Newport Beach Mediation, LLC upon relocating back to Southern California in 2005. Thus establishing Newport Beach Mediation as a premier entity in the Southern California mediation community.

In 2017, Ronnie, channeled his mediation skills back into the world of professional sports. This came by way of his then 38 year relationship with Los Angeles Lakers and the Buss family. In February of that year Johnny & Jeanie Buss, with the cooperation of the Lakers Legal Department, reached out to Ronnie requesting that he take an active role & intervene in order to prevent any escalation and legal challenges within the Buss/Laker Family. Since that day, Ronnie has worked closely with both of them on a number of fronts from the family, to the Los Angeles Lakers, to Johnny Buss's long time love of comedy which resulted in him purchasing the world renowned comedy club, The Ice House in Pasadena. In light of Ronnie’s long running history with Dr. Jerry Buss, Ronnie considers his accomplishments within the Buss family some of the most personally rewarding of his entire career.

Jerry Buss and Jerry Colangelo, then owner of the Phoenix Suns and Arizona Diamondbacks, lured Ronnie back into the professional sports field in 1991. With their guidance, Ronnie built what many will argue was the most successful professional sports league, at inception, ever created in the United States; the Continental Indoor Soccer League, CISL.Ronnie and his legal staff were the first professional sports entity to develop what is now commonly known as the single entity formula. The CISL consisted of 15 teams primarily made up of NBA and NHL owners along with a number of entrepreneurs throughout the US and Mexico. The CISL was the first professional sports league in North America to have teams from Mexico.

As founder and Commissioner of the League for its entirety, Ronnie oversaw and was involved in every aspect of the league from national marketing and advertising to national television negotiations to player/management disputes. Under Ronnie’s leadership, the CISL had over 50 percent of its teams turning a profit by year three, secured a 3 year nation wide deal with Fox Sports to televise prime time and negotiated a 3 year, multi-million dollar, deal with General Motors. Ronnie's mediation skills truly became fine tuned while playing the middleman in all league disputes and negotiations. During his tenure as Commissioner, Ronnie served on the Board of the United States Soccer Federation for the duration of the CISL.

In 1989 Ronnie decided to step away from professional sports. He entered into the world of music entertainment by teaming up with Jerry’s eldest son, Johnny Buss, to create Buss-Weinstein Productions, an entity geared towards developing wholesome music television for the “tween” generation.

In 1982, Jerry Buss called upon Ronnie to create and bring to fruition the Los Angeles Lazers professional indoor soccer team of the Major Indoor Soccer League (MISL). Along with Johnny and Jim Buss, Ronnie oversaw every aspect of operating a major league professional sports team from 1982 to 1989.

Upon graduation from UCI in 1978 Ronnie joined Jack Kent Cooke, then owner of the Los Angeles Kings and Los Angeles Lakers, in the marketing and promotional field.

Dr. Jerry Buss purchased the Lakers, Kings, and Forum in 1979 under the umbrella of California Sports. Ronnie remained with California Sports for the next 11 years. While under Jerry's reign, one of Ronnie’s major accomplishments was playing a key roll in the creation of the Senate Seat Program which became the foundation for what are now commonplace suites in all entertainment venues throughout the US. Ronnie also cofounded the Los Angeles Lazers of the Major Indoor Soccer League MISL with Johnny Buss, Jerry's eldest son.

Ronnie's sports management career began in 1977 at the University of California at Irvine, when he was hired by UCI’s Athletic Director to fill the first ever roll of Student Assistant Athletic Director.

During the summer months and School Vacations Ronnie helped to perfect his communication/people skills by working as tour guide at Universal Studios Hollywood.
