About Brianna

Assessment for clarity, performance, and the future. I’m Brianna Staley Shumaker, PhD, a board-certified clinical psychologist providing psychological and cognitive assessment for adults, particularly high-performing professionals. A primary service in my practice is cognitive baseline assessment for healthy adults who want to understand and document how their brain is functioning today. This establishes an objective benchmark that can be used in the future if cognitive changes, illness, injury, or concerns arise. I also provide comprehensive evaluations for ADHD, autism, personality, and complex diagnostic questions—particularly when symptoms overlap or the correct diagnosis is unclear. My forensic and occupational services include fitness-for-duty, employment and pre-employment evaluations, FAA psychological evaluations, and select legal/forensic evaluations. Self-referrals and professional referrals are welcome, including referrals from psychiatrists, therapists, physicians, attorneys, and employers.
