Adult ADHD Evaluation in Marietta
ADHD Testing for Adults in Marietta, GA
Comprehensive, structured ADHD evaluations for adults with Dr. Alex Crenshaw at Peachtree Psychology's Marietta office.
You have wondered for a long time. Maybe you have always struggled to finish things, stay organized, or keep your focus where you need it. Maybe a therapist suggested it, or you recognized yourself in something you read. Or maybe you have been managing - just barely - for years, and you are tired of it.
A formal ADHD evaluation does not tell you what is wrong with you. It tells you what is actually going on, so you can stop guessing and start getting the right support.
Dr. Alex Crenshaw offers comprehensive ADHD assessments for adults at Peachtree Psychology's Marietta office. These are structured, thorough evaluations - not a quick checklist - designed to give you clarity and a clear path forward.
Do Any of These Sound Familiar?
Adult ADHD often looks different than people expect, especially when someone has spent years compensating.
You start tasks easily but cannot finish them, or you hyperfocus for hours and lose track of everything else
Deadlines feel manageable until suddenly they are not
You have been called "smart but scattered" your whole life
You are forgetful in ways that feel out of proportion: missed appointments, lost items, dropped threads
You have tried therapy, productivity systems, every app, and nothing sticks the way it should
You suspect ADHD but your doctor or previous therapist was not sure
These patterns do not always look like what people picture when they think of ADHD. In adults, especially those who developed strong compensatory strategies in school, ADHD can be subtle, inconsistent, and easy to misattribute to anxiety, stress, or personality. A diagnostic evaluation is the only way to know for certain.
Why a Formal Evaluation Matters
ADHD is frequently underdiagnosed in adults, particularly in people who succeeded academically or learned to mask their difficulties early. It is also frequently confused with anxiety, depression, and sleep disorders - conditions that can look nearly identical on the surface but require different treatment approaches.
It documents what you are dealing with.
A formal report with clinical findings can support accommodations at work, applications for academic support, and informed conversations with prescribers.
It gives you a starting point.
Whether the answer is ADHD, something else, or both, knowing changes how you approach treatment.

Frequently Asked Questions
How do I know if I need the Full ADHD Assessment or the Standalone Diagnostic Evaluation? ▼
The phone screening at the start of the process helps answer this. If your concerns are focused specifically on ADHD and a comprehensive evaluation is clinically warranted, the Full ADHD Assessment is the right fit. If you are seeking clarity around a broader range of concerns, such as depression, anxiety, or OCD, the Standalone Diagnostic Evaluation may be more appropriate. Dr. Crenshaw will help you determine which path makes sense for your situation.
Does insurance cover this? ▼
This evaluation is offered on a self-pay basis. Dr. Crenshaw does not bill insurance directly. Upon request, a superbill can be provided for potential out-of-network reimbursement through your insurance plan. Coverage varies, so contact your insurance provider to ask about out-of-network psychological testing benefits.
Why does the evaluation cost $2,300? ▼
A comprehensive ADHD assessment is a multi-session, multi-method process. It includes your clinical interview, structured diagnostic procedures, computerized testing, scoring and interpretation, the full written report, and a 90-minute feedback session. The cost reflects the clinical time involved, not just the testing itself.
How long does the process take from start to finish? ▼
After your initial phone screening, the in-person testing session takes most of a Saturday morning. Report preparation and the feedback session add additional time. Dr. Crenshaw's office will walk you through the full timeline when you schedule.
Do I have to stop my ADHD medication before testing? ▼
If you are currently taking medication, this will be discussed during your phone screening. For the computerized testing portion, you will be asked to avoid caffeine and stimulants on that day. Specific guidance for prescription medications will be addressed individually.
