Go to Gillette Children's Specialty Healthcare in St. Paul (Regions Hospital.) My son was having some behavioral issues that puzzled his teachers, and our pediatrician (at Central Peds) sent us to Dr. Raymond Tervo at Gillette. We had an impressively thorough (and long! it took eight months from start to diagnosis) evaluation - audiology, opthamology, extensive psychological eval, and an OT eval. It took a long time, but by the time we got to a diagnosis (which did, full disclosure, end up being ADHD) both my husband and I felt truly confident that it was accurate and appropriate.
Feel free to contact me if you have more specific questions about our experience.
