Katja is that very rare combination of expertise coupled with a friendly nature and without any degree of intolerance or lack of respect for those of us who use computers but really do not understand them! Her explanations are clear and concise and her speed of work is quite remarkable. After an unfortunate earlier experience with another she has been a real “breath of fresh air” for my Wife and I. Thank you so much Katja. May our relationship be a long and happy one.
