About ADHD Philadelphia: Adult ADHD Evaluation & Treatment in Pennsylvania and Delaware
Clear answers. Compassionate care. Practical adult ADHD treatment.
ADHD Philadelphia provides specialized adult ADHD evaluation, testing, treatment planning, medication management, and executive-function support for adults throughout Pennsylvania and Delaware.
Our focus is adult ADHD. We work with adults who may have struggled with attention, procrastination, organization, time management, working memory, follow-through, emotional regulation, or other executive-function challenges for years—sometimes without realizing that ADHD may be contributing.
Some patients come to us because they have always suspected ADHD. Others have built successful careers, completed advanced education, raised families, or developed complicated systems to compensate, yet still feel that everyday responsibilities require far more effort than they should.
The goal is not simply to assign a diagnosis. The goal is to understand the full picture, identify what may be contributing to your difficulties, and develop a treatment plan that supports more sustainable day-to-day functioning.

Meet Charles Thornton, PMHNP-BC
Charles Thornton, PMHNP-BC, is a board-certified Psychiatric Mental Health Nurse Practitioner and the provider behind ADHD Philadelphia.
His practice focuses on adult ADHD evaluation and treatment, including diagnostic assessment, computerized cognitive testing when clinically appropriate, medication management, treatment planning, and practical strategies for executive-function challenges.
The approach at ADHD Philadelphia is collaborative, respectful, and individualized.
ADHD does not look exactly the same in every adult. Symptoms can be influenced by work demands, education, family responsibilities, sleep, stress, co-occurring mental health concerns, medical conditions, culture, relationships, and the systems a person has developed over time to compensate.
For that reason, ADHD evaluation should consider the whole person rather than relying on a single symptom checklist or computerized test.
Why ADHD Philadelphia Exists
Adult ADHD can be misunderstood.
Some adults spend years hearing that they need to try harder, become more organized, stop procrastinating, use a planner, or simply become more disciplined.
But when ADHD is present, the problem may involve differences in attention regulation and executive functioning rather than a lack of intelligence, motivation, or concern.
ADHD Philadelphia was created to provide adults with a clearer and more accessible pathway to evaluation and treatment.
Our goals are straightforward:
Provide respectful adult ADHD care without unnecessary stigma.
Make the evaluation process easier to understand.
Maintain transparent appointment pricing.
Help patients understand how ADHD may affect real-world functioning.
Consider alternative or co-occurring explanations for symptoms.
Develop treatment plans based on the individual rather than a one-size-fits-all approach.
Provide convenient telehealth access throughout Pennsylvania and Delaware.

Our dedicated guide explains how ADHD can affect demanding careers even when overall performance appears strong.

Adult ADHD Evaluation at ADHD Philadelphia
Adult ADHD diagnosis should not be based on one symptom, one questionnaire, or one computerized test.
The evaluation process considers your current concerns along with your broader clinical and developmental history.

During this appointment, we may review:
Current ADHD symptoms
Childhood and developmental history
School and academic experiences
Employment and professional functioning
Relationships and household responsibilities
Time management and organization
Emotional regulation
Sleep
Medical history
Mental health history
Current and previous medications

Step 2: ADHD Testing & Results Review — $150
When ADHD testing is clinically appropriate, the $150 ADHD Testing appointment includes both the ADHD testing and the review of your testing results.
Testing may include computerized cognitive assessment and standardized ADHD rating scales.
Testing can provide useful information about areas such as attention and other aspects of cognitive functioning, but testing is not interpreted in isolation.
Your results are considered together with your clinical history, symptoms, functional impairment, developmental history, and other relevant information.

ADHD Is About More Than Attention
Many adults initially think ADHD is simply a problem with concentration.
In reality, ADHD can affect several executive functions that help adults manage everyday responsibilities.
Executive functions help the brain decide what to focus on, begin tasks, remember information, manage time, organize responsibilities, regulate reactions, adapt when plans change, and continue working toward longer-term goals.
ADHD Philadelphia has developed an extensive educational resource center covering these areas.
Executive Function Topics Include
Working Memory
Time Management & Time Blindness
Task Initiation
Emotional Regulation
Planning Skills
Organization Skills
Prioritization
Sustained Attention
Response Inhibition
Goal-Directed Persistence
Self-Monitoring
Cognitive Flexibility
Explore the Executive Function in Adults With ADHD Resource Center
Understanding these individual skills can help adults describe their difficulties more accurately than simply saying, “I cannot focus.”

Respectful, Individualized ADHD Care
Adults often arrive for ADHD evaluation after years of wondering why certain responsibilities seem more difficult than expected.
Some have previously felt dismissed.
Others have learned to hide their difficulties because they are successful at work, academically accomplished, responsible for other people, or afraid of being judged.
ADHD Philadelphia strives to provide care that is respectful, collaborative, and free from unnecessary stigma.
We recognize that ADHD experiences can also be influenced by culture, race, gender identity, sexual orientation, family expectations, professional responsibilities, neurodiversity, and previous healthcare experiences.
BIPOC adults and LGBTQ+ adults are welcome at ADHD Philadelphia.
Adults who would like to learn more about how race, culture, healthcare experiences, and ADHD care can intersect can explore Adult ADHD Care for Black & BIPOC Adults.
Our goal is to understand your individual experience rather than assume that every adult with ADHD looks or functions the same way.
