What is Neuromodulation Therapy?

Neuromodulation therapy uses gentle, targeted stimulation such as mild electrical currents, magnetic fields, or infrared light to stimulate cellular energy, healing and regulation of the nervous system. By promoting neuroplasticity, this therapy helps the brain form healthier patterns to improve mood, sleep, cognition and performance.

Neuromodulation May Benefit the Following Conditions:

Concussions & brain injuries
Migraines & headaches
Dizziness & balance disorders

Neuropathy
Anxiety & depression

Our Neuromodulation Services

At NeuroAxis Health in San Francisco, we offer a full spectrum of non-invasive neuromodulation therapies designed to improve brain function and quality of life. Each treatment is guided by qEEG brain maps that reflect your unique brain patterns, and specific needs to support healing and recovery from physical and neurological injuries.

Photobiomodulation (PBM)

Safe, therapeutic light (near-infrared, far infrared, or red light) absorbed by your cells to boost energy production, healing, and repair. Research suggests benefits for concussion recovery, stroke, cognitive impairment, and neurodegenerative conditions.

Vagus Nerve Stimulation (VNS)

Provides mild, controlled stimulation to the vagus nerve, which influences mood, stress, and body regulation. VNS is an approved treatment option for depression, migraines, and certain headache syndromes.

Trigeminal Nerve Stimulation (TNS)

Applies gentle electrical stimulation to the trigeminal nerve, helping modulate pain, regulate mood, and support cognition. Studies show promise for migraines, depression, and chronic pain conditions.

Stimpod Pulsed Radio Frequency Stimulation (PRFS)

Delivers controlled radio frequency stimulation to peripheral or cranial nerves. Supports nerve repair, neuromuscular strength, and relief from pain conditions such as nerve injuries, headaches, and mobility challenges.

Audio Visual Entrainment (AVE)

Uses light and sound pulses to guide brain activity into healthier rhythms. AVE supports relaxation, better focus, mood regulation, and improved sleep. Research suggests benefits for stress, anxiety, ADHD, and headache disorders.

What a godsend! I had been suffering near constant debilitating migraines from a car accident injury that kept getting worse. I tried steroid shots, radio frequency ablation, you name it, I was desperate to get rid of the awful pain and regain my once active life. Dr. Jesse Tolentino at NeuroAxis is a true miracle worker. Such impressive skill and very compassionate, she has changed my world with her committed care to my healing. I was a bit scared at first because I have a really tricky neck with many complications including osteoporosis. But she assured me with her experience in resolving such issues. Thank god I'm able to function normally again! I can't say enough good things about this wonderful doctor. I highly recommend going here. You will be well taken care of...

I am seeing both Dr. Tolentino and Dr. Chung for sleep issues (I wake up pretty much every hour) and migraines on occasion. My sleep patterns have improved significantly. I am now doing remote-neurofeedback and doing my treatments before bed. Training my brain to sleep through the night. So grateful for these two Docs!

Before I went to Dr Chung, I was having imbalance issues, unable to move my eyes in certain ways without causing immediate and severe neurological issues, and plagued with insomnia and night terrors. Dr Chung's treatment was literally the ONLY thing that helped improve my symptoms.

He genuinely cares about his patients' wellbeing and is even willing to work with them on financial issues. I can't recommend him enough!

Dr. Chung is the best in the city, along with his entire staff who are all so friendly, caring, and knowledgeable! I had a horrible nerve issue that was ongoing for a year post-ankle fracture surgery, and saw 5+ doctors that couldn’t diagnose or figure out why I was having the issue. At one point it was difficult to even walk or day to day activities without feeling chronic pain. Then I saw Dr. Chung, who helped me beyond addressing the root cause - and provided a holistic and long-term treatment. My treatment included advanced red-light therapy, physical therapy, chiropractor sessions, and recommendations for lifestyle changes. He’s changed my life for the better, now living pain-free and back to a very active life - so couldn’t recommend Dr. Chung and his team more!

This is a place where healing happens. My brain and I are in a much better place than when I walked through the doors 5 1/2 months ago. Dr. Chung and Dr. Jessica know how to transform the quality of life for each and every patient. My family and friends are happy to see the new me. I’m grateful that I chose NeuroAxis Health and I hope you do too.

Dr Chung was extremely attentive and caring, and had a lot of tools in his belt. I felt that he was genuinely determined to help me heal my migraines. Really quality care, and a myriad of offerings.

In just a few months, Dr. Chung has made such a difference in my life. When I came to Dr. Chung about my migraines, I was at the end of my rope. I’d tried just about every preventative pharmaceutical on the market and was still having migraines multiple times a week, usually requiring triptans for relief. Within weeks of working with Dr. Chung, I was experiencing significantly fewer migraines and today I am happy to report that I’m two months headache-free. I feel better than I ever thought possible and am working with my primary care physician to taper off preventive pharmaceuticals. I know this would not have been possible without Dr. Chung and his team.

Dr. Chung has a comprehensive, innovative, and compassionate approach to diagnostics and care -- he really tried to get to the bottom of what was causing my migraines, and then designed a customized program of treatment that included neurofeedback, chiropractic adjustments, laser and electrical stimulation, and balance and visual rehab. At each step of the process, he explained the data and science behind the process, which helped engage me in the treatment. He is and his colleague, Dr. Fox, are also incredibly kind, and it is a pleasure to work with them. I am so grateful for their work.

Dr. Chung is the reason I’m a functional human again. I had 2 serious head traumas that left me severely impaired, and he helped me heal and resume cognitive and neural functions. I was a wreck! People don’t believe me when I tell them how I was after my injuries. Forever grateful to him. Super knowledgeable, kind, patient, and overall wonderful human! I recommend him to anyone & everyone who suffered a concussion. He’s the best!!

Working with Dr. Chung has been revolutionary for my traumatic brain injury. For the last few years, I have been experiencing post-concussive symptoms related to vision, balance, and coordination. I came to Dr. Chung feeling defeated and hopeless and through his in-depth assessments, he put many of the pieces together and provided personalized treatment that targets my weaknesses. He keeps all of the details in mind when creating the exercises so that nothing is overlooked or missed. He provides his treatment with the push, persistence and understanding that I need to overcome my symptoms. If you are someone who is suffering from balance, vision issues, concussions or brain injury symptoms, Dr. Chung will provide you the right help towards recovery.

Dr. Chung is everything you’d want in a practitioner; he’s kind, knowledgeable, caring and exceptional in his skills. I originally came for migraine help (and haven’t had a single migraine since my first appointment) and am excited to continue the work on this through his very holistic and comprehensive approach (adjustments, Biofeedback and more). Last week I had a serious inflammation in my knee which completely debilitated me. Just left his office with range of motion and significant less pain after he carefully and methodically worked to uncover the source of the injury and how to relieve the pain and adjust the muscles and joints. He also sent me home equipped with gentle exercises to continue the healing. I’ve seen many practitioners in my life and so far Dr. Chung stands out in all the ways that matter when choosing a doctor.

I've been seeing Dr. Chung since July of 2016 for a lower back issue I developed nearly a decade ago playing collegiate soccer. I've seen a number of chiropractors, orthopaedists, and physical therapists in the interceding years but nothing seemed to work. However, Dr. Chung has managed to accurately diagnose and treat me. I still see Dr. Chung occasionally for routine maintenance as I can't seem to stay away from the soccer field! Dr. Chung's a personable and considerate professional and is a pleasure to work with.

I came to Dr. Chung because of an injury I sustained in a car accident. I'd been to several doctors previously who were unable to heal my injuries and I was suffering from post concussion symptoms as well as a great deal of neck and back pain.

What I liked best about working with Dr. Chung is how patient he is with me and how he takes the time to answer every single one of my questions. Healing from an injury this big can be a very scary experience but I was glad to know I was in very kind and capable hands.

I fully trust Dr. Chung, I think he cares about his patients and he is ALWAYS driven by his desire to help heal people. He came into this practice because of his own experience healing from an injury and that is helpful because it makes him empathetic since he knows how it feels to be the patient as well.

I am truly grateful to Dr. Chung for helping me through this experience and I will be revisiting him for maintenance care as long as I live in the Bay area.

Dr. Chung has helped me with several different issues. I've had problems with a fractured foot, different back problems, and a concussion.

One of the problems with my back I've had for many years . Since I've been seeing Dr. Chung my problem has cleared up completely. I'm able to do things now I could not do before without having a flare-up with my back.

Dr. Chung is comprehensive in his evaluations. He often finds areas I didn't know were not working right and I feel so much better after his treatment.

He is very kind and caring. He is a good listener and educates his patients about how you can continue to improve your health.

I've also had some cognitive issues and was beginning to withdraw from some parts my life. With Dr. Chung's help and recommendations for home self-care I'm feeling better overall.
