What is Gonstead Chiropractic?

The Gonstead Method isn't just a technique—it's a philosophy of chiropractic care that we embrace wholeheartedly at Intero Chiropractic. This method differs from traditional chiropractic due to its meticulous approach to diagnosing and addressing spinal misalignments. Here, we don’t just use Gonstead; it is the cornerstone of our practice, ensuring every patient receives the highest standard of care.

How Does It Work?

Detailed Analysis

An intensive assessment—combining detailed health history with a full spinal examination and cutting-edge tools like the Nervoscope.

Precise Adjustments

We perform adjustments with surgical precision. By targeting only the specific vertebrae that require correction, we ensure impactful, minimal interventions.

Meet Your Team of Doctors

Dr. Zakariya (Zak) Champa received his Doctor of Chiropractic degree from Palmer College of Chiropractic in San Jose, CA. One day, while playing football, he injured his lower back and couldn’t walk for two weeks. He found a Gonstead Chiropractor who helped him eliminate all pain in the first two adjustments. This inspired him to pursue chiropractic as a career to help others experience being freed from pain.
He is a passionate Chiropractor at Intero Chiropractic, where he is known for his precise adjustments and warm smile. Dr. Zak is on a mission to meet all types of people and get them to a better quality of life.

He’s attended more than 250 hours of Gonstead seminars so that he can remain focused on improving the health of patients and applying the Gonstead technique to transform their lives. In his free time he enjoys basketball, tennis, golf, billiards and taking hikes in nature or spending time with family.

Dr. Andrew Apuya, a graduate of Life Chiropractic College West in Hayward, CA, brings a unique blend of personal experience and professional dedication. Born and raised in Winnipeg, Canada, Dr. Apuya initially pursued a Bachelor’s Degree in General Science at the University of Manitoba. His journey into chiropractic care was sparked by personally dealing with severe low back pain and muscle spasms. The remarkable improvement he experienced through chiropractic care, including relief from headaches, muscle spasms, and enhanced sleep and digestion, motivated him to help others achieve a similar transformation in their health.

With over 200 hours of specialized seminars, Dr. Andrew has honed his skills in the Gonstead technique. His goal is simple: to improve the quality of life for his patients through the power of chiropractic care. In his free time, Dr. Andrew enjoys exploring new foods, going to the beach, listening to music, and practicing hip hop dance.

Dr. Michael earned his Doctorate of Chiropractic from Palmer College of Chiropractic in San Jose, CA, graduating with honors as a member of Pi Tau Delta. Originating from Taiwan, he is fluent in both Mandarin and Taiwanese. His educational journey also includes a Bachelor of Sports Medicine from Chinese Medical University in Taiwan.

Having played baseball since high school, chiropractic was pivotal in helping him overcome the numerous injuries sustained both on the field and in daily life. These experiences fueled his passion for the field and led him to pursue a career where he could offer the same relief and support to others.

Dedicated to his craft, Dr. Michael has invested over 100 hours in Gonstead seminars, aiming to refine his skills and deepen his understanding of this specific chiropractic technique.

Outside of his professional life, Dr. Michael enjoys staying active and engaged through hobbies such as playing baseball and basketball, golfing, and relaxing while watching TV shows.

Dr. Carlos graduated from Life Chiropractic College West in 2020, following his studies in Anthropology and Legal Studies at UC Santa Cruz in 2012. Born in Palm Springs, CA, and fluent in both English and Spanish, his path to chiropractic was deeply personal. Witnessing his mother's long struggle with back pain after a work-related injury in 2001, Dr. Carlos initially aspired to become an attorney to support her legally. However, the limitations of legal remedies and a desire to make a more direct impact on people's health led him to pursue a career in chiropractic instead.

His goal as a chiropractor is to provide lasting relief and elevate the standard of care by truly listening to patients and improving their mobility and function. Understanding the value of movement from his mother's experience, Dr. Carlos is passionate about helping others regain and appreciate their ability to move freely.

Dr. Carlos has received special training in the Gonstead technique, aligning with his commitment to offer precise and effective chiropractic care. Outside the clinic, he enjoys watching anime, reading psychology books, hiking and camping, exploring coffee shops, and conducting research. He also loves running with his German Shepherd around the lake, embracing an active lifestyle that mirrors the mobility and freedom he seeks for his patients.

What Our Satisfied Patients Are Saying

5 out of 5 stars


Here is a perspective from someone who was not a believer at all in Chiropractic care. I stumbled upon this clinic at a local city fair we were having and I had been struggling with severe sciatica for over 2 years. On this particular day I was in so much pain so figured I would give their pitch a listen.

Dr. Zack was so thorough in his approach and explaining to me where we would be correcting based off of x rays. The x Ray was very comforting knowing they were using data to address what was wrong and causing the pain.

My whole experience here from appointment reminders to being able to easily reschedule adjustments if needed was 10 out of 10.

The best part after about 3 months I have no more pain. It's gone. I know there is still work to be done to completely fix these lower back issues but having the relief after 2 years is something you can't put a price tag on.

I'd highly recommend coming here and taking a dive of faith if you were skeptic like I was. My experience here has been nothing short of amazing.


Can't even begin to express how awesome my journey has been at Intero. The staff is awesome, flexible scheduling (including last minute changes), and of course Dr. Zack. He was the best ever. Majority of my back issues have been resolved and looking forward to doing some form of maintenance to keep the improvement Dr. Zack adjusted. Thanks Intero :))


I recently switched to Intero Chiropractic after a few months of not seeing any real results at a different chiropractic office. From my first appointment, I knew this place was the real deal. They conducted a series of tests and scans that my previous office did not. I've suffered from chronic migraines for a few years now and after about a month of working with Dr. Zak, they're just about completely gone! I've had only one headache since beginning the adjustments, but I felt the difference after just the second session. I never write reviews but honestly this place has been a life saver. I am used to getting a headache about every 3/4 days and it is almost strange to have gone this long without one. I'm also happy about the fact that they address the multiple issues I was concerned with under the same plan. My last chiro would charge a whole different price for sinus adjustments but at intero it's super convenient that all of my issues will be taken care of without having to worry about paying extra. I'm super excited to see how I will feel after completing their adjustment plan. I plan to come back and update this review once complete!
