Don is a knowledgeable, caring instructor. I have been with him for 3+ years now. He has worked diligently with me, gradually making me stronger and more flexible at a safe pace. Safety is his priority so once you communicate to him you have a back problem or knee issue he is sure to adapt his teaching style to suit your needs. He's very friendly and his classes are usually small (no more than 6 people) so you get one-on-one attention. His prices are also reasonable. I highly recommend Don over any Pilates instructor in Dallas.
