About Mert
Over 10 years of treating children and adults
Our Process

Begin with a consultation with our clinician and have your qEEG taken, analyzed, and interpreted. These steps will help determine if MeRT is a good fit for you.


A personalized treatment protocol is developed based on your qEEG. Per your protocol, gentle magnetic waves are applied to targeted areas of your brain in our office by one of our technicians. Each treatment period is 2 weeks (Monday-Friday).

Progress Monitor & Evaluate

Every 2 weeks, surveys and scales are collected to help us monitor your clinical response to treatment. Near the end of each treatment period, a follow up qEEG and clinician consultation is done to evaluate your progress and guide additional treatment.

Synapse Parent of a Child with ADHD

Are you having issues with your child getting into trouble at school?  Or do school administrators ask you if you’ve had an assessment of your child?  Let me tell you, Dr. Yim and his staff saved our family!  If we didn’t stumble on Synapse, we would still be receiving daily behavior updates, with no clue what to do. Going through the therapy has been a game changer!  Rather than having to call my son 10 times before I get a response, he now answers by the first time.  This has truly been life changing and a blessing.  Thank you Dr. Yim, Audrey, Hope, Mel, and Shirley!  You guys are miracle workers!!  Thanks!

After just about every conventional treatment failed to reduce my PTSD symptoms, Magnetic e-Resonance Therapy at Synapse Hawai’i proved to be totally transformative for me. It significantly reduced my anxiety & depression, greatly improved the quality of my sleep, and had a lasting positive impact on my mood — truly remarkable considering it’s non-invasive, painless and does not involve the use of any pharmaceuticals. Dr. Yim patiently guided me through the science and helped me at every stage to optimize the treatment protocols for my specific condition and symptoms, while the MeRT technicians were always gentle, supportive & knowledgeable. I cannot recommend MeRT at Synapse Hawai’i enough for anyone who, like me, has struggled with treatment-resistant PTSD. Mahalo, Synapse Hawaii!

In the early phase of treatment, even though he slept, he didn’t sleep very deeply (didn’t sleep 9-10 hours deeply). After we came to Synapse, he started sleeping 9, 10, and even 11 hours a night. After he stopped taking his medications, he didn’t experience any side effects even though he did have side effects due to the medications. If it wasn’t for this treatment with Synapse, I don’t think this would’ve been possible. The way he speaks even changed after starting treatment. He puts more emphasis and emotion into the way he speaks rather than being monotone. He can even multi-task in a way where I talk to my child and he is something else at the same time after the treatment. This wasn’t possible before. He is able to be more playful with children his own age and be more involved in his group compared to before. Before, he wasn’t able to understand when a certain thing is appropriate to do at a certain time. For example, he really wanted to do something at this moment but couldn’t comprehend why he couldn’t, even though it was inappropriate to do so at that time. This issue has been overcome. Before, he didn’t want any material items but now he emphasizes more than he really wants something. The biggest thing I have noticed is my child’s ability to generate more emotion with everything. As for eating, he has become more open to eating compared to before. Before, he used to cause a fit when trying to be fed by me. Now, he is enjoying eating food by himself. His favorite food is ketchup! I never imagined him to change this much. I question myself if my child needs to keep continuing this treatment at Synapse Hawai’i. I recommend other people to consider this treatment because I never imagined how much it would improve my son’s life and how effective it would be. Doing this treatment was a last option for my child and it seemed to have worked to a great extent!

Mother of a Child with Autism

As a mother of an autistic non-verbal, six-year-old daughter, we went into MeRT not expecting much change. Dr. Gregory Yim and staff has exceeded my expectations with the MeRT. After our 6-week treatment with Hope and her kind patient ways with my daughter, we came out with more positive than could be imagined. My daughter has become more focused in school and at home. For the first time, she actually called her dad, ‘Dad,’ with she never said before. Her aggression has dramatically decreased. I’d always be bruised from her pinching, biting, and scratching but it has altogether stopped. Mahalo nui loa Dr. Yim and Staff!

Mother of a Child with Autism
Traveled from Korea for MeRT

This summer our child was treated at the Hawaii branch. There were many worries and difficulties, but I think it was a good thing to do. In terms of interaction, there are more and more areas where you can see positive changes. And after returning to Korea, you can sometimes see new expressions. There are still many problems to overcome, but I feel much more comfortable compared to before treatment. Even the slightest changes mean a lot to children and their families, so I recommend that you receive them with a little more relaxed mind rather than expectations that may be too grand. Thanks again to therapist Kyanna for always being kind and giving us the best despite our lack of communication 🙂

Traveled from Korea for MeRT

We did MeRT at the Hawaii center with my brother who has autism. It was not much easy to try this treatment in another country but I think it’s worth it. There are some positive changes with his interaction and more new benefits have occurred even after coming back to Korea. We still have many other problems to go through but he looks more calm and comfortable compared to before. Thanks a lot again for Dr. Yim and Kyanna technician who gave us all her best and for always being nice even we have language barrier 🙂

Synapse Parent of a Child with Anxiety

Synapse and MeRT made a huge difference for my son. He suffered from frequent anxiety attacks (several per week). The staff at Synapse were very kind and knowledgeable. They made the MeRT sessions fun and painless for my son. We did 6 weeks of treatment (5 days a week) and the improvement has been profound. His anxiety attacks have almost completely disappeared. This made a huge, positive difference for him at school and at home. Thank you Synapse!

Traveled from Korea for MeRT

I treated my child at the btc center in Hawaii in the winter of 2022. My child was diagnosed with autism in Korea and has a lot of difficulties. So, I tried various special treatments in Korea, but the results were disappointing. After much consideration, I did not have high expectations even though I was receiving treatment at the BTC Center in Hawaii. But by the end of the treatment, I noticed a definite change. However, I was curious about how people would react to this change I felt when I returned to Korea, and I wanted to see if the effect would be maintained.

This is the reason I am writing this after a month since I returned to Korea. My child has increased basic interactions since treatment and so far. The quality of eye contact and action imitation improved, and the number of verbal expressions increased. Also, my child often wakes up at dawn, but the quality of sleep has also improved. There is still a long way to go, but I hope it gets better. Although special treatment has been performed in Korea for a long time, no treatment has changed the quality of eye contact like this. Also, Hawaii’s weather, sea, and relaxation seem to have helped a lot. If I have a chance, I would like to visit the Hawaii btc center again. Finally, thanks to Dr. Yim and Kyanna for their kindness and professionalism.

Frankly speaking, we did not anticipate a dramatic miracle from the treatment coming to Hawaii. The most valuable lesson we have learned through this treatment was that we now understand the reasons behind my son’s behaviorism. We understand better why he acts in certain ways. We also realized a little more about the directions we should consider and approach in order to find solutions. Conclusively, the best treatment result we experienced was we noticed much better eye contact.  My son responded much more naturally when his name is called. We saw curious eye contact rather than discipline/trained eye contact.”
