Best for
Children (5+), teens, and adults whose families want a veteran-owned, DNP-APRN-led practice that can complete autism or ADHD evaluations either in the clinic or via telehealth — with eight major insurers accepted.
Their approach
Evaluations are built around a doctorally prepared, APRN-led model supported by a multidisciplinary team that includes early childhood and counseling expertise; assessments can be paired with pharmacogenetic testing (GeneSight) and the Tranquility360 Mind+Life psychoeducation program.

A free 30-minute pre-testing consultation is offered before you commit; intake forms are completed online, and testing happens remotely or at the Kingwood center — reach the scheduling line at (832) 879-2107.
