ISO- Puppy Social Anxiety Trainer

I have a 12 wk old dachshund that has pretty severe social anxiety. I am trying my best right now with finding people that can come in and out until she has all her shots for daycare but I also really want to work on her anxiety (also obedience).

Are there any trainers in the Houston area (or Katy, clear lake, pearland, etc) that are reputable for specifically dealing with social anxiety?

TIA
