"I needed security cameras installed, and I am so glad I ran across Mitchell through Angi. I canâ t say enough good things about this guy! He was on time and communicated well in person and through text. He was fast, efficient, thorough, honest, hardworking, and just an overall decent guy. Once again, my wife and I are so glad that we ran across Mitchell at Freedom Electrical, and we are looking forward to working with him on future projects!"
