      • "I can not speak highly enough"

        I can not speak highly enough for the experience I have received from Cogan & Power Attorneys at Law. I was introduced to John Power through a mural friend. I was impressed from the very first phone call with John Power to us meeting through the pandemic. His professionalism and his medical knowledge is unbelievable… I have to say from that day moving forward John Power, Sara Davis and Kim Stefanek all put me at ease. My cases lasted just about 3 years and I was notified every step of the way on what was going forward and keeping me in the loop. John and Sara made sure that I was ready and comfortable for my Deposition, they made sure every stone was unturned! Kim Stefanek is one of their paralegals and she is awesome. I can go and I highly recommend Cogan & Power for your legal issues. John Power & Sara Davis are amazing attorneys and exceptional, caring, compassionate people!!
