Prior to joining Hasan, LLC in 2017, Brian was the Staff Attorney for Ent Credit Union, a $5 billion financial institution headquartered in Colorado Springs. As sole in-house counsel for Ent, his responsibilities included negotiating and drafting all contracts with vendors; re-writing and significantly enhancing the third party management program; ensuring compliance with stringent regulations for financial institutions; collaborating with and supervising outside counsel in the defense of claims; drafting, reviewing, and revising policies and procedures for various departments; and providing advice and support for unique member situations such as lending against trust assets and distribution of assets to beneficiaries in accordance with wills and trusts. Through this experience, Brian became knowledgeable of the day to day legal needs of businesses, effective strategies for negotiation, and methods to successfully build collaborative coalitions.

“After gaining valuable experience as in-house legal counsel, I had a strong desire to enter private practice and work closely with a variety of successful entrepreneurs and business. Based on my prior experience, I knew Hasan, LLC would be a perfect fit.”

As a Denver native, Brian enjoys everything outdoors Colorado has to offer – from hiking and camping in the summer to skiing and snowboarding in the winter. He is also an avid soccer and softball player.
