We met with Dr. Christina Ralph at Mindwell Psychology -
http://www.mindwellpsychology.com/ . We didn’t have them do the testing, as we already had a lot done through the school, we just had them look through everything the school had done and the reports they’d written for DS to advise if we needed more and whether there was anything more we should ask for to be put on our IEP. I could not have been more happy with Dr. Ralph. She asked for all our reports ahead of time and really read them in detail so I didn’t have to re-teach everything when I got there; although it would’ve been in her financial interest to recommend additional testing, she was very clear that she didn’t think we needed more or that she had anything that would give us extra information; and when DS's IEP was ready – two weeks after my appointment with Dr. Ralph and when she knew I wouldn’t be coming back for services – she STILL read the whole thing and gave me really good feedback and I didn’t have to pay any extra money.
I was interested in sticking with them for counseling services - but their location (Herndon or Chantilly, I forget) and my home were too far apart to make it convenient.
