“I contacted Don at High Swartz for legal guidance for my brother whom had people he was allowing to live at his residence for a 2 months. They did not leave when they were suppose to so Don guided us with the steps to have them removed in the most gentle, but firm way possible. I chose Don, because I know he cares a lot about his clients, he is very thorough, and is outstanding in his profession. With the well written letter from your office, the people living in my brother’s home realized that we were serious about them leaving the premises and they did not have any legal right to remain there. My brother and I am very thankful for Don’s guidance in this matter, resulting in them moving out of my brother’s home.”
