I don't know the area at all mroades, but what is not close (I have to drive 50 miles to get to anything so my definition may be different than others -- also traffic isn't an issue where I am -- don't know about Charleston)?
I only got one reply and it was for Herritage Hall? I guess there is a trainer there that trains at a few barns though....and her name is Charity....I have her number if you want it....just pm me. Good luck in your search!!
Heritage Hall is nice--love the covered arena... I have a friend that boards out there. It's a bit far with traffic from the area the person would like to be in, I think. And I don't know that Charity has the best program for adult beginners...
I know a girl who lessons at Silver Meadows Stables and she loves it. Also I know a girl who takes dressage lessons at One Tempi Farm; not sure if they do beginners but she really likes it too so it might be worth checking out.
Not sure where you are located, but we have just built a new facility off of Hwy 41 N about 15 min north of Mt. Pleasant. We will be starting a lesson program in the next few weeks. While we specialize in ponies, we do have a couple of lesson horses and plan to offer lessons to all ages.
