Who We Are

The M Center was founded by two mothers on a mission, Dr. Maia and Dr. Monica. After walking through the experience of healing our own children with a Functional Medicine approach, we discovered our children were a catalyst to the realization of our life mission – to share our expertise, insight, and healing approaches with other families like our own.

Since we have personally experienced Autism, ADHD, anxiety, Sensory Processing Disorder, and learning difficulties, we truly understand the physical, mental, and financial stresses that are placed on the entire family. It is our mission to offer a medical home for all families, so they may be heard and cared for.

By combining our skills, expertise, and experiences, the concept of healing from the heart was born. Our experiences from both sides of the exam table as patients, parents, and healthcare professionals has provided us with priceless insight to help others along their journey to healing.

Monica Beckham, PhD, FMCHC

CEO and Clinical Director

I’m Dr. Monica Beckham and I hold a doctorate in Health Communication & Research. I am also a Functional Medicine Certified Health Coach, through the Institute of Functional Medicine. I specialize in personalized genetic nutrition analysis, holistic treatment options, biofeedback and energetic healing. Through a personalized plan for your child, I work with your family to provide education, guidance, and support through the ups and downs of healing your child! I have an amazing 7-year-old son.

Our Philosophy


Our goal is to help families separate signal from noise. Parents today are bombarded with confusing and often conflicting information regarding the optimal way to raise their children. The M Center helps parents parse through this information, creating a meaningful, personalized, and unified plan for how to help your child grow to be their best selves. The M Center uses a Functional Medicine paradigm to identify underlying patterns within a constellation of behavioral and health symptoms in children and adolescents. Once this key information is teased out, families can chart a course toward wellness.

We firmly believe in a collaborative care approach with our families. We do not believe in predetermined protocols as every patient is an individual. The journey to healing is a process that does not move in a straight line. We encourage parents to bring any and all information to us regarding research they may have discovered, things they may have heard from a friend or an online forum, or any other questions or curiosities. We believe in open and honest dialogue as something you mention could be beneficial for your child and others!

We look forward to meeting your family and joining you on our healing journey!
