Prior to founding Bridge West, Jim began his distinguished career at a national accounting firm in Boston, MA and then spent more than 30 years as the owner of a public accounting practice that assisted small businesses reach their financial goals. After gaining an in-depth understanding of corporate accounting, partnership, and individual taxation, Jim founded his private practice in Longmont, Colorado in 1984. At his predecessor firm, Jim oversaw a team of experts who provided clients with full service accounting, business valuations, and expert witness services. In 2009, prior to the passage of HB 10-1284 and SB 10-109, the Colorado Medical Marijuana Code, Jim performed extensive research on the cannabis industry. Realizing the significance of the emerging industry, he searched for solutions regarding renting property to growers and/or dispensaries, opening a dispensary, supplying product to dispensaries and many other issues facing this new industry. Jim then traveled to San Francisco, California to meet with attorneys and accountants involved in the Champ case and other medical marijuana clients. As a result of his research, Jim decided to focus on the cannabis and hemp industries.

In 2015, Jim merged his non-cannabis clients with a CPA firm in Longmont, Colorado and dissolved Jim Marty and Associates, LLC.  At that same time, he created Bridge West LLC, a new firm exclusively focused on the cannabis and hemp industries In 2017 his practice was acquired by Boeckermann Grafstrom & Mayer, a full-service CPA and Advisory firm founded in 1982 and located in Bloomington, St. Paul, and Sauk Centre, Minnesota, and Florida.

In recent years, Jim and the Bridge West team have expanded into assisting clients in the hemp industry. Beginning with the 2014 Farm Bill and with President Trump signing the 2018 Farm Bill, hemp and CBD companies are a significant part of Bridge West’s client base.
