Dart Winkler represents clients in complex contract litigation and fiduciary responsibility cases, as well as cases involving insurance, construction, real property, banking and creditors’ rights, derivative shareholder suits, employment law, and injunctive relief. Mr. Winkler also counsels financial institutions and other partners in credit and collections matters, dishonest business practices, lender liability, depository agreements, discriminatory and predatory lending, wrongful foreclosures, and problem loan workouts.

Mr. Winkler litigates to defend insurance providers against policyholder claims, to protect and assert terms of real property contracts, and to protect the rights of homeowners with regard to enforcement of covenants, assessments, insurance, and contracts. He often collaborates with construction attorneys to resolve disputes on behalf of owners, contractors and suppliers in construction claims related to bad faith, breach of contract, defects, insurance, liability, liens, and property damage caused by design and other defects. Mr. Winkler also represents policy holders in claims against insurance carriers, including disputes based on catastrophic losses. His experience working for both sides on insurance-related disputes provides insight others may lack, leading to an objective review of the facts and related policy language.

Mr. Winkler is experienced in all facets of discovery and case management including depositions, client negotiations, and drafting of case documentation, memoranda, and motions. He collaborates with clients to develop and enact best business practices, and is also experienced in jury trials, arbitration, mediation, and administrative proceedings when conflicts should arise.

In appropriate cases, Mr. Winkler works with clients and opposing parties to attempt to resolve disputes through means alternative to litigation. Clients often find that alternative dispute resolution is best approached with a clear understanding about the strengths and weaknesses of their case, and a willingness to continue with litigation in the event the discussions end without resolving the dispute. Mr. Winkler helps guide clients through that process.

Mr. Winkler helps breweries and distilleries with a wide range of business and legal issues likely to arise in this continuously developing market. In addition to attending and participating in legal courses on brewery and distillery law relating to common issues, he has consulted with other professionals in the industry, including banking and marketing specialists that focus on these growing and developing businesses. He has turned a social pastime into a professional mainstay.

Familiarity with the law and procedures in these jurisdictions facilitates a more comprehensive approach to legal representation. He is also available to work with other attorneys as local counsel in locations throughout Colorado and California.
