I know that the regulars are going to notice me harping on this point over and over (as we often get your "where to start" question),,,but I'll say it again...Ballroom dance is a buyer beware market! You will find that ballroom dancing (like any hobby) can tie up a signifigant amount of funds. So, be sure you have a good, reputable instructor right from the very beginning! Know why you want to dance...are yo ujust into being a better dancer, or are the social aspects more important? Either way, start calling those studios in the yellow pages and ask them if they have any instructors certified by the ISTD or the USISTD (US Imperial Society of Teachers of Dance). If they meet the standards of the ISTD exams then you can at least be sure that they are knowledgable. Hopefully you'll find several certified teachers...then you can take lessons with all of them and find a studio, or instructor that suits you personally.
I am in KansasCity...we have roughly 6 studios here, but ONLY ONE with experienced and certified instructors. Doesn't mean that the others aren't doing well enough teaching a lower standard of social dance...but many students realize (much to their chagrin) that they need better instruction only after spending a lot of time and money with a very inexperienced and sadly undertrained instructor. So, my advice is simply to do a little looking around first...and don't get emotionally attached (laugh now but it often happens) to a studio or teacher who will ultimately disappoint you.
That said, don't give up! If you love to dance then you will surely find a way to pursue it...besides, men are always in high demand...if we had a decent amateur male in KC looking to do amateur competition there would be a huge cat fight over him!
