Dan Holdwick, PhD Licensed Psychologist in Michigan

Welcome to GLPG and Holdwick Psychological Services. I provide psychological evaluations [child, adolescent, adult] for:

• ADD/ADHD
• Autism Spectrum / Developmental
• Disability / Workman’s Compensation
• Emotional Support Animal
• Gender Confirmation Surgery
• General Diagnostic/Psychological Evaluation
• Memory and related cognitive concerns (dementia)
• Military Fitness for Duty
• Presurgical evaluation (e.g., bariatric, kidney, liver, etc.)

Upon scheduling an appointment, you will be emailed an Intake (Life History) Questionnaire to complete prior to your initial intake. This helps guide the initial interview and selection of psychological testing. Upon completion of testing, Dr. Holdwick will meet with you to review test results, ask clarifying questions that may arise from testing, provide recommendations and answer questions you may have.

The overall structure of a psychological assessment tends to follow this pattern:

1.       60-minute Initial Diagnostic Interview

2.       Psychological Testing is done online, at the client’s pace and schedule. For example,

a.       Autism Spectrum / Developmental: broad symptom questionnaire, daily functioning questionnaire(s), Autism specific questionnaire(s)

b.       ADHD: Broad Symptom Inventory, Cognitive Concerns Questionnaire, Cognitive Performance Test, ADHD specific questionnaires,

c.       Disability/ Emotional Support Animal (ESA)/Workman’s Compensation: broad symptom questionnaire, daily functioning questionnaire(s), cognitive concerns questionnaire and cognitive performance testing as relevant to claimed condition(s)

                   NOTE: Each are dependent on specific details of the state/federal agency and regulations involved and their definition of “disability”.

d.       Memory/Dementia: Broad Symptom Inventory, Cognitive Concerns Questionnaire, Cognitive Performance Test, additional symptom questionnaires based on history (e.g., trauma, depression, anxiety, mood)

e.       Military Fitness for Duty & General Diagnostic/Psychological Evaluation: broad symptom questionnaire, daily functioning questionnaire(s)

f.         Presurgical: Questionnaire specific to pre-surgical candidates, broad psychiatric symptom questionnaire.

Most assessments will include some brief additional symptom questionnaires based on current identified concerns and history (e.g., trauma, depression, anxiety, mood)

3.       60–90-minute Follow-up Interview.
