Ms. Cox was more than helpful in updating our phone messaging system. She was easy to work with, offered suggestions for improvements and was professional at all times. We received numerous comments from both our patients and referring physicians about the quality of our new message. I would strongly recommend her for voiceovers or narration at any business.
