Adam M. Trenk

Adam M. Trenk practices law in the areas of public policy, zoning, aviation, equine, and business transactions. He also works as a strategist consulting across multiple industries on matters of government relations and corporate development, and is an entrepreneur.

Adam has been with Rose Law Group pc since 20210 and was named partner in 2018. Trenk is the founder and chair of Rose Law Group’s Equine Law and Aviation Law Divisions, and blends his passions and his profession by capitalizing on a wealth of knowledge accumulated from living actively engaged in these industries.

The Equine Law division at Rose Law Group is the most robust in the State of Arizona. Built upon the equestrian knowledge Adam accumulated from a lifetime of involvement in various disciplines across the country, his team can handily facilitate a range of transactions including breeding, boarding, buying, selling, or leasing of horses. He is also able to help resolve conflicts and litigate matters arising out of the pursuits of horsemen and women.

As chair of the Aviation Division, Adam is also available to assist with anything related to the business of civil aviation. He understands the intricacies of owning and operating aircraft and he and his team can guide you through the complex business transactions and matters of regulatory compliance with local, state, and federal agencies that the industry entails.

Drawing on his experience helping maximize the productivity of agricultural operations, Adam has positioned Rose Law Group’s Hemp Law Department as the premier hemp practice in Arizona. Under Adam’s direction, the Hemp Law Department has worked closely with the Department of Agriculture to formulate the rules that govern the state’s new and growing hemp industry.

Adam has been instrumental in Rose Law Group’s Cannabis Law Department since its inception when he began in the area working on the original implementation of Arizona’s medical marijuana program. Adam draws on his considerable experience in business transactions and navigating the cannabis industry’s legal landscape to support Rose Law Group’s clients in all facets of their cannabis businesses.

He attended Arizona State University, where he obtained a Bachelor of Science in Small Business Management and Entrepreneurship from the W.P. Carey School of Business (2005). After graduating he launched a career in real estate, working for a New Jersey based real estate investment firm and then branched out on his own as a real estate property asset consultant while investing in and managing his own investment properties and pursuing his education.

Adam went on to earn a Masters of Real Estate Development (2007) and then his Juris Doctorate (2010) from Arizona State University. In law school, Adam built his curriculum around alternative dispute resolution and real property law. In addition to Arizona, Adam is now licensed to practice law in Kentucky and Oklahoma.

Adam has been active in his community, serving as a board member for the Cave Creek Merchant’s Chamber of Commerce and sitting on the Citizen’s Advisory Committee to the Town Council prior to making a run for a Council seat himself. Adam was first elected to hold a seat on the Cave Creek Council while he was in law school in 2009. He did not run for re-election in 2011, but in 2012 established a PAC that successfully defeated a ballot initiative aimed at implementing a new property tax. Adam Trenk was re-elected to the Council and served as Vice Mayor from 2013 to 2015.

In 2014, recognizing a threat to the helicopter tourism industry in the Greater New York City area, Adam worked to establish the Helicopters Tourism & Jobs Council (HTJC), organizing industry stakeholders and coordinating a lobbying effort and public relations campaign to ensure the continued viability of the helicopter operators in and around New York City. Adam continues to serve as the executive director of the HTJC today.

Adam’s work in local government, his experiences practicing as an attorney, and his efforts to develop and preserve business interests in the aviation sector give him a unique perspective. He is able to navigate complex regulatory schemes and negotiate to add value in legislative affairs and transactional matters.

Adam feels strongly about giving back. He was once very active with the Communication Alliance to Network Thoroughbred Ex-Racehorses, CanterUSA, a 501c3 that rehabilitates and rehomes horses off the track.

Recognizing the importance of education and supporting the industry that helped him develop his work ethic, Adam serves on the Advisory Board for the Scottsdale Community College Equine Science Program.

In addition to his philanthropic pursuits, Adam is an entrepreneur. He acquired the Billy Cook Harness & Saddle Manufacturing, Inc. in 2019, saving it from bankruptcy after the passing of the company’s namesake. He preserved more than twenty jobs in so doing. He has rebranded the company Genuine Billy Cook Saddles which continues to operate a business that is internationally recognized as one of the finest western saddle manufacturers in the world since 1953. Adam is working to expand Genuine Billy Cook’s offerings to appeal to a broader demographic than dedicated horsemen, and they now incorporate branded merchandise and apparel.

Adam’s worked to establish Charm Aviation, LLC, a part 135 air carrier that operates helicopters for sightseeing and charter in the greater New York City Area in 2021. (www.flycharmny.com).

Adam has been a lifelong western horsemanship enthusiast. Throughout high school and college, he spent several summers as an apprentice horse trainer in Montana and Idaho. Today his home is in Cave Creek, AZ and he has a small horse breeding operation on a ranch outside of Sulphur, OK. He splits his time between the two.
