I am listed on Thumbtack too, but not impressed. The leads you receive tend to be looking for the “cheapest” trainer and I don’t think a lot of them even follow through with hiring a trainer. It’s a cheap way to advertise, but I don’t think it is effective. However, if a lead contacts you directly you can submit a quote and response for free. So, I would stay listed but I wouldn’t rely on the leads they give you.
