· GRE · In studio The instructor was very professional and extremely well prepared. She tutored me for the GRE exam for about five months, and I can honestly say that my preparation was boosted by her great teaching skills as well as careful lesson planning. The sessions were planned in detail in order to work on all of the three sections of the test, paying particular attention to those topics that needed extra practice first. Weekly material was brought to class, and homework were regularly assigned and checked. The tutor was reliable and could be reached by email during the week for any questions and/or clarifications regarding the course work. Would recommend to anyone.

· · Great with kids

My 10-year-old daughter has studied with Kate for several months now, and we both adore her. Not only is Kate extremely knowledgeable about many aspects of singing and performing, but she knows how to impart that knowledge to a young student in a way that is both effective and fun. Brava!
