I've been around a few NYC dance studios (BDC, Alvin Aileys, etc.) and private instructors so I feel confident in the following assessment of Dariusz.
So far I've attended a few private salsa and hip hop dance lessons with Dariusz since this spring and found his style both enjoyable in terms of keeping the mood and feeling positive, while still providing solid technical and engaging feedback that would improve my dancing and general performance.
Dariusz rises to the top as someone who puts more than the average amount of thought and preparation not only into his material, but how he delivers his message. His methods, presentation and information are all rock solid. His awareness of technical terminology, basic dynamics, combined with a desire for excellence means he creates lessons that are just challenging enough to help you create a solid foundation and to have fun in the meantime.
Dariusz is one of the most well-trained, reliable, and most experienced salsa & hip hop instructors in the NYC Area. I recommend seeing him whether you are an absolute beginner, like me, or a competitive professional.
Keep up the good work Dariusz!
