Welcome
At Second Brain Immunity, we look beyond the diagnosis to the gut-brain connection — often called the body's "second brain" — as a key piece of your child's developmental puzzle. Serving families throughout Marietta, Cobb County, and the greater Atlanta area, Dr. Angela Karvounis uses specialized testing to identify the underlying imbalances (nutritional, immune, environmental) that may be contributing to your child's symptoms, then builds a treatment plan personalized to what your child's own body is telling us. Our mission is to help your child grow and thrive with results you can trust, and a process that gives you clarity every step of the way.
We Focus On The Root Cause
Our Specialized Biomedical Treatments can create lasting changes in your child's life. By addressing the "Second Brain" we aim to uncover and resolve one of many root causes of developmental delays and autism. We also address many other underlying issues such as:
-Vaccine Injury
-Chemical Exposure
-Pans/Pandas
-Heavy Metals
-Mitochondria Issues
-Neurotransmitter Imbalances
-Nutritional Deficiencies
-Methylation/Sulfuration Pathway Irregularities
-Immune System Imbalances
-Microbiome Dysbiosis/Leaky Gut
***Specialized testing is key to finding root causes of symptoms.

The Second Brain
At Second Brain Immunity, we focus on the gut-brain connection to improve your child's overall health. We examine the essential role of the Vagus Nerve, a key pathway that links the gut and brain's sensory communication. Research is now calling the Vagus Nerve the Sixth Sense of the body. This Nerve is crucial for promoting calmness, reducing anxiety, and maintaining a balanced immune system. The Vagus Nerve connects to all major organs and is especially responsive to the gut microbiome, significantly impacting children with special needs. Our aim is to promote a healthy microbiome, helping these children experience meaningful improvements in mood, focus, and overall well-being.

Dr. Angela is an angel on earth. My son has been with her for roughly 7 years and she has walked me through the highs and lows. He has shown great improvements throughout the years. We thought we would never hear him speak and by the grace of God and Dr. Angela - something that seemed unreal, was achieved. The best investment, for your child!

She is a MAPS Doctor and is very intelligent and knowledgeable about the treatment of ASD and other special needs. She helped me and my wife get started on the journey of healing for our Daughter. She was 4 at the time. She is 6 now and is speaking almost full sentences & has ZERO issues with socialization and playing. In fact nowadays its the "other kids" that don't want to play with her. Not the other way around!

If you're on the fence about starting with "Second Brain Immunity" read this fully and start your child treatment today. When I first received my son diagnosis of AUTISM. I was heartbroken and didn't know where to begin my sons healing journey. I knew nothing about Bio Med nor did my pediatrician tell me about it. I started getting in autism groups and that is when I discovered biomed. From that point I started searching for the best doctor to be able to help me with my sons journey with autism.
