Utilizing his strengths, Stefan makes his clients feel comfortable and breaks down each piece of their plan cutting through the legal jargon and providing quality advice.

Stefan enjoys working with clients to help them understand and develop a strategy that solves their problem and alleviates their concerns. Stefan says, “When my clients and I execute the final plan, often one resulting from multiple sessions discussing and strategizing with that client, it’s a great feeling knowing that my clients understand the importance of what they’ve done and the impact it will have on their lives and the lives of generations to come. Building legacies is extremely meaningful work.”

Stefan’s profound commitment to his clients and his ability to make complex legal matters easy to digest makes everything he does ‘Worth It’ and a valuable asset to the Goosmann Law Firm.
