Angela Sporopolis was an excellent instructor. Myself and my co-worker learned a lot. Angela was very patient which I think was tested very much that day.

Patrick, the owner of CTS, is great to work with. He cares about his clients. He makes himself available for advice and consultations. This is a great place to further your education.

Angela was a great teacher instructing both Part A and Part B of Photoshop to virtual classes of ~8-10 people. She knows the subject matter forwards and backgrounds to be able to answer any and all questions the classmates asked. At some point in time, I would like to take Photoshop again. Rose K.
