I'd give 6 stars if I could.  I've worked with Jenni, Cathy, and Suzanne to rehabilitate after a painful back injury.  I couldn't do conventional mat exercises, so they developed a personalized set of exercises I could do on the reformers.  Within a month, the pain had largely disappeared.  Pilates helped me heal and gain strength; now I'm working on flexibility.  I've continued because The Pilates Studio staff is so knowledgeable, professional, and supportive.
