Wendy Bonnen, Ph.D. & Associates provides comprehensive assessments of children, adolescents, and young adults who are thought to have developmental or behavioral problems, autism spectrum disorders, attention-deficit/hyperactivity disorder (ADHD), or learning disorders such as dyslexia. We also provide services to children, adolescents, and young adults with other emotional and social difficulties such as mood and anxiety disorders, trauma exposure, adjustment problems, and interpersonal difficulties.         
















After a careful diagnostic assessment of an individual's strengths and weaknesses by an experienced, licensed psychologist, we will develop an intervention plan and make referrals for treatment if needed. 


We also offer parent and school consultation services to develop and implement highly individualized interventions with parents and school professionals.

The Assessment and Diagnostic Process:

  • Diagnosis of developmental conditions, including ADHD, specific learning disorders, and autism spectrum disorder, as well as diagnosis of anxiety, mood, and behavioral concerns

  • Comprehensive evaluation of an individual's development, including intelligence, language, attention, learning and visual motor skills, social and emotional functioning, and academic abilities, such as reading, math, spelling and writing

  • Individualized consultation regarding assessment results and referral for intervention

  • Comprehensive clinical reports

  • Follow-up appointments and reevaluation (when appropriate) for monitoring progress and response to interventions



Insurance & Fees:

  • Full payment for comprehensive assessments are due at the time of the initial appointment, unless you are being referred for an Independent Educational Evaluation (IEE) by your child’s school district, for which a signed contract and billing arrangements will be obtained in advance.

  • Fees for consultation services are due at the time services are rendered.

  • Dr. Bonnen is not a provider with any insurance plans; however, services provided are eligible for out-of-network reimbursement by insurance companies, depending upon clients' coverage constraints. 

  • We accept Visa, MasterCard, Discover and American Express, as well as cash and checks.


Developmental Assessment
For children ages 3 to 5 years

Includes parent interview; standardized measures of cognitive, language, memory, attention, pre-academic and motor and/or visual-motor development; play observation; review of any previous records; review of teacher or caregiver ratings; parent feedback meeting; and comprehensive written report with recommendations.



Parent Consultation


Sessions in which parents are able to talk with the psychologist about parenting challenges and receive expert guidance on child development and some of the social, emotional, and learning issues that are present. Consultations can occur on a periodic or regular basis. This can also be a time to talk about school supports and other activities that may enhance a child’s development..



Psychological or Psychoeducational Assessment
For children ages 6 to 13 years


Includes parent interview; standardized measures of cognitive, language, memory, attention, academic, and visual-motor development; child interview; review of any previous records; parent feedback meeting and comprehensive written report with recommendations.



School Consultation


We offer consultation to school staff as a method of establishing interventions for a student in a specific educational environment. School consultation is a collaborative process between the psychologist and school staff in an effort to promote success for students who are struggling. Together, the psychologist and school professionals develop specific interventions to help the student become more successful.



Adult ADHD Evaluations


These evaluations include a diagnostic interview, questionnaires, and brief cognitive measures. We also evaluate psychological and emotional functioning to rule out other issues that can exacerbate attention difficulties.



Psychological or Psychoeducational Assessment
For ages 14 to young adulthood
Services are the same as above. When needed, reports are structured to fit 
guidelines for documentation of need
for testing accommodations for
college entrance exams.






The comprehensive assessment process consists of three to four appointments:


The initial appointment in the assessment process includes a diagnostic interview with the parent(s) lasting approximately one hour. At the time your appointment is scheduled, parent(s) will be emailed several questionnaires which should be completed prior to your appointment and turned in when you arrive. These will include a developmental history form, a behavior measure, and a questionnaire for your child’s teacher(s) or another caregiver who interacts with your child on a regular basis. In the interview, the psychologist will collect information about your child’s developmental and family history, functioning at home and in school or childcare, any previous testing and intervention services, and recent events surrounding the reason for the current evaluation. 


The second and third appointments consist of direct assessment of your child. There may also be additional parent-report measures administered to obtain detailed data regarding the child’s communication skills, social-emotional skills, independent self-care and daily living skills, and/or atypical behaviors. Direct assessment of children younger than four years of age may take place with parents present in the room. Four to five year olds, and children of any age with significant developmental delays, may be evaluated separately or with parents in the room, depending on the child’s ability to separate from the parents and the level of the child’s communication skills. Typically, older children and adolescents will be evaluated separately from parents. The direct assessment portion of the evaluation typically lasts between three and four hours for younger children and up to seven hours for older adolescents and young adults.


We use a variety of different tests and observational measures depending on the age of the child and the presenting problem(s). Evaluation of younger children will typically include assessment of general cognitive development, speech and language (expressive and receptive skills), fine and gross motor function, social interaction skills, and play skills. Assessments for school-aged children and adolescents generally include intellectual ability, attention, memory, academic skills, executive functions, social-emotional functioning, and fine motor function/handwriting.


The final appointment is a parent feedback meeting that will be scheduled for one hour at a mutually convenient time. At the time of the feedback meeting, the psychologist will meet with the parent(s) to review the results of the evaluation; provide a diagnosis or diagnoses if appropriate; answer questions; and provide recommendations for interventions, school or classroom placement, relevant community services, medical follow-up, or other referral suggestions as appropriate. Often we can provide you with specific names of recommended therapists, tutors, schools, or programs that can meet your child’s needs. We also often provide informational handouts regarding your child’s diagnosis and/or specific issues, and we will recommend a schedule for follow-up assessments to monitor your child’s progress and continuing needs over time. Adolescents, and school-aged children upon request, are welcome to attend part of the feedback session if they choose to hear a summary of the results and recommendations and have their questions answered.
