Arnold is a partner at Straus & Eisler PA, a general practice firm. He formed the firm in 2000 with Michael Eisler, with whom he shared the same philosophy of how to practice law: treat the clients as part of the family, and they will remain clients for life. Arnold began taking pro bono cases from Legal Aid in 1994. He has handled 20 cases since then, including Real Property, Probate, Estate Planning, Family Law, Employment, and Housing for both Broward Lawyer’s Care and the Veterans Pro Bono Project.
