I asked my friend Rebecca who sees a doctor out in Webster, and she e-mailed this back:
"My infant son and I both see Christian Wessling at Webster Family Physicians on Big Bend. Dr. Wessling is an MD who also works in homeopathic medicine. He's a family doctor rather than a pediatrician, though he sees tons of kids. He's reserved, which may not make him especially easy to talk to for some, but very thorough, unhurried, and a good listener. He has a lot of ideas about asthma and allergies and nutrition in general that might be helpful for your son. I don't like the nurse-practitioner on staff quite so much (but she's perfectly competent in a pinch). I wouldn't recommend the practice to someone who wasn't open to alternative medicine, but it sounds like you might be a great fit. And you can't beat the location!"
Hope this helps!
