For anyone looking for voice instruction, Linda Strasser is a pro. I had learned so many bad habits over the years, but working with Linda really helped me improve my diction and my range, and also helped reduce the negative "self-talk" which often occurs at a subconscious level, like the one which says, "Oh, no, here comes that high note!"
I've been working with Linda for several years, and I can honestly say she is well worth the money... she uses various techniques to help target a student's trouble areas, and makes it fun at the same time. If you want to work with a professional, I highly recommend Linda.
