I am a neurodivergent-affirming psychologist who helps adults seeking assessment. I help my clients answer the questions, "Am I autistic? Do I have ADHD?" Neurodivergence can look different in women and AFAB individuals, and it sometimes does not follow the stereotypes of what autism or ADHD are. Having a psychologist who specializes in these areas can be very helpful. Discovering neurodivergence later in adulthood can be a very positive event for many, helping them understand themselves and their life experiences more deeply.

Sometimes it is difficult to navigate life and the curve-balls that it throws at us! Having to get through the day and struggling with anxiety or feelings of depression are just a few. Maybe you endured a traumatic event and it's been causing you trauma and distress. Perhaps you have a child that has been diagnosed with Autism Spectrum Disorder (ASD) or Attention Deficit hypo/hyperactive Disorder? If so, your child may be having difficulty with paying attention, controlling emotions, communication or social interactions. I'd love to help build upon your strengths and help you further succeed in this world that we are navigating!

If you have been frustrated by past therapy experiences, you’re not alone. Traditional therapy approaches don’t always work for those of us with ADHD, Autism, and other types of neurodivergence. That’s why I do things a bit differently. My approach is strengths-based, empowering, and neurodiversity-affirming. Instead of trying to fit a square peg into a round hole, neuro-affirming therapy embraces the squareness. It recognizes that what works for one person may not work for another, and that's perfectly okay.

Autism Therapists

What is the most effective treatment for autism?

Applied Behavior Analysis (ABA) has come to be considered the standard treatment for children with autism spectrum disorder, and research has confirmed its effectiveness for many children. Therapists trained in ABA techniques work with children (and their parents) on developing social skills, communication and learning abilities, and everyday habits of hygiene and grooming. The clinician will tailor their program to the child’s particular need but the overarching goal will be to help them advance as far as possible toward independence based on their level of symptoms and decrease the need for additional special services. Families should seek a mental health professional specifically trained in ABA, and holding special certification in the technique, who has extensive experience not only with the approach but in using it with children with the same level of symptoms as the child who needs care.

How does ABA work?

Applied Behavior Analysis (ABA) sessions, which typically focus on positive reinforcement, can be intensive, lasting two or more hours several times a week, and continuing for two years or more. Therapists can also be expected to ask parents to take an active role in reinforcing lessons. Research has found that the technique can lead to major improvements that decrease the need for additional special services.

How does treatment for autism work?

Therapy sessions based on Applied Behavior Analysis will likely be frequent, intensive, and highly structured. After a thorough assessment, a therapist will help a child understand and develop skills in a range of areas, including communication, motor skills, social skills, self-care, play, and academic skills, as well as routines of daily living like hygiene. Typically, the therapist will help a child break down the components of a behavior—often referred to as the antecedent (what prompts an action), the behavior, and the consequence(what immediately follows)—and then reward the child at every step, while also asking parents to reinforce the lessons, and the rewards, throughout the day. This core therapy may be supplemented by occupational or speech therapy, and antidepressants, antipsychotics, and anticonvulsants may be prescribed to address specific severe symptoms.

How long does therapy for autism take?

Some people with autism spectrum disorder may be engaged in some level of therapy for many years, but research shows that treatment will be most effective if it is begun early and delivered intensively. When therapy begins by age 3, children tend to be better able to grasp and adopt the skills needed to manage everyday life, including attending school and establishing social relationships. This type of early-intervention treatment regimen is highly structured, typically involving 20 to 40 hours of one-on-one therapy per week, along with additional hours of engagement managed by parents, for a period of two years or more, although the duration of treatment is dependent on the child’s level of symptoms and pace of progress.
