Our Practice
We are a quality based practice. What does that mean? We believe that good medical care is predicated on our relationship with the families in our practice. That means we value lengthy well visits and will take the time that you and your child need to get to the bottom of any health issue your daughter or son is experiencing! We hope to become a meaningful part of your child's life and growth!
THE PRACTICE
What is the MTHFR gene?
The MTHFR gene is a genetic mutation carried by a proprotion of the population. It can be responsible for anxiety, ADHD, autistic spectrum disorders, and future health complications.
Why is baseline concussion testing so important?
The impact is a specialized test which is very sensitive at finding even mild injury. A baseline impact is instrumental in determining the safest return to school and sports plan for your child. Drs J and M are certified to administer testing at our office. Call to schedule your appointment today.
