Does anyone know about this dr?(Reading,PA area)

My chiro recommended Dr. Joseph T. Kang to me today. She has met with him and really liked him. He is a part of Callowhill Medical Associates on N. 5th st . (Other drs in the practice are: Dr. Jamie Schrenk(do) and Dr. Claire Murphey ). My almost 5 month old has a bad curve in her spine and my chiro strongly suggested getting her fully checked out by a dr(She also has low weight gain). But I just feel our current dr is a waste of time. I was going to switch to Stiner Medical (http://www.steinermed.com/html/about_steinermed.html ) But if there was a good dr closer that would be wonderful,lol!

So if you know anything about Dr. Kang or Callowhill Medical Associates I'd love to hear it! Thank you!
