Ronnie was born and raised in New York. He has always had a passion for the Colorado Rocky Mountains. Throughout high school, college, and law school he made many trips out west to spend time on the ski slopes. During that time he also discovered a love for business and the law. He attended Cornell University for their excellent business program, and received his Bachelor's of Science in Business Management and Marketing in 1999. While attending Benjamin N. Cardozo School of Law he was able to spend a summer at the Central European University where he concentrated his studies on alternative dispute resolution techniques including arbitration, mediation, and negotiation. He received his Juris Doctorate with a concentration in alternative dispute resolution and intellectual property in 2003. With a law degree in hand, Ronnie moved to Colorado to be nearer to the mountains he loves. He was admitted to the Colorado Bar in 2003. Since then, Ronnie has focused his legal career to assist clients in the areas of intellectual property (i.e., copyrights, trademarks, and patents), business, real estate, personal injury and probate law. When Ronnie is not working, he is happily enjoying all the wonderful outdoor activities that Colorado has to offer: skiing, mountain biking, tennis, white water rafting, and four-wheeling.

Over his more than three decades of practice, David Japha has earned a reputation for resolving difficult and complex matters, sometimes being the second or third lawyer to take on a case. David has tried many criminal and civil cases to conclusion and argued numerous appeals, post-conviction cases and cases involving mental health issues. He also currently represents clients in federal and state administrative matters, including ongoing matters before the Consumer Products Safety Commission. David got his start in litigation before leaving the University of Denver College of Law, where he tried his first DUI case in state court through a program called the student law office. He also negotiated settlements and argued his first administrative appeal before the Social Security Administration in the winter of 1984, before his law school graduation in May of that year. Soon after starting out, David shared office space with his current partners, Don Jacobson and Daniel Levin at Ptarmigan Place. There he learned law office management hanging out his shingle and doing evictions, collections and court-appointed federal criminal cases. And, it was there, in federal court, that David truly cut his teeth in criminal defense litigation, culminating in his appointment to the Criminal Justice Act committee (which oversaw the appointment of conflict counsel in federal court) by then-Chief Judge Richard Matsch. Over 30 years of practice has given David the opportunity to be involved in some amazing cases, including taking depositions in Katmandu, Nepal in a complex criminal case in 1991; representing a witness in the trial of Timothy McVeigh (where David was also a credentialed reporter for the Intermountain Jewish News); handling criminal matters in Nebraska, Kansas and California and appearing in Washington State. David has been an expert witness for the Colorado Supreme Court Office of Regulation Counsel in the area of attorney fees for court appointed counsel.
