Dr. Adam Martinez received his Doctor of Chiropractic degree from Parker University in Dallas, Texas. Originally from Amarillo, Texas where he was heavily involved with sports his entire life, thus, graduating with a bachelor's degree in Sport and Exercise Science.

Dr. Adam's first experiences with chiropractic prior to attending college were underwhelming, to say the least. The combination of his sports background, past experiences and overall lack of chiropractic knowledge led him to believe that he would go into chiropractic school with a focus on exercise and rehab. However, he saw the amazing physiological healing abilities we all possess and how Chiropractic can affect these processes. So, he wanted to find the "Gold Standard" of the 250+ chiropractic techniques when entering graduate school and quickly focused in on the Gonstead System dues to its scientific and systematic approach to health.

So far, Dr. Adam has accumulated 200+ hours of Gonstead Techniques outside of the curriculum, has been certified in Upper, Lower and Advanced Gonstead Extremities, 20+ hours of Gonstead Pediatric Care and 400+ hours with Chiropractic mentors ranging from 17-36 years of experience in the Gonstead System.

Spending time with his wife and 2 young children is Dr. Adam's favorite past time (along with watching the Philadelphia Eagles).


Dr. Anthony Lai received his Doctor of Chiropractic degree from Life Chiropractic College West in Hayward, CA with a full scholarship.

Though he was born in Canada, Dr. Anthony spent his early childhood in Hong Kong. He then went on to study abroad in the United Kingdom and graduated from Durham University with a bachelor's degree in Biomedical Sciences. The human physiology has always fascinated Dr. Anthony, but it was not until discovering chiropractic that he truly understood what the innate body is capable of.

Dr. Anthony has been practicing the Gonstead system for over 3 years. He has accumulated over 200 additional hours in Neuro-Structural chiropractic. He loves to give back to the community and has been on volunteer mission trips to serve underprivileged patients all over the world!

Aside from spending time with his family and friends, Dr. Anthony loves to travel and explore the world whenever he has the opportunity. He believes that food is the gateway to culture. When you come to the office, ask him where he's been!


Do you take insurance?

We currently only take Medicare and Personal Injury/Auto Accident cases. Although we would love to get reimbursed for our services, most major medical insurance companies only reimburse for traditional chiropractic services, and do not reimburse for most of the things that we do above. However, we can give you a receipt/superbill to submit to your insurance for out of network benefits.

Can you give me an adjustment on my first visit?

Our best care is after we thoroughly complete our 45-60 minute analysis of your 30+ point exam, full spine x-rays, thermography, etc. (see above), which is typically performed in the evening (yes, we stay late!). In certain acute scenarios, we can definitely perform an abbreviated analysis, but this is not preferred.
