  1. I have many lovely memories of Katie. I was Corrie’s friend and therefore saw Katie often. I think of her as a professional woman and also a very caring family person. She was bright, humorous and always interested in people. She was also very friendly to my own mother. She was very blessed to receive the wonderful care Corrie gave her in her last years.
