About The Functional Medicine Center

The Functional Medicine Center in Irvine was founded by Dr. Steve Hyjek to provide natural healthcare solutions using the best diagnostic testing and treatments. Designed for clients seeking real solutions and results, the center offers services including Functional Medicine, Lab Testing, Chiropractic Care, Holistic Medicine, and Low Level Laser. Patients have praised Dr. Steve’s ability to listen carefully and tailor treatments to individual needs, leading to effective results. Many have experienced significant relief from issues such as back pain, Hashimoto's symptoms, acid reflux, joint pain, headaches, and gastro problems.

One patient, who had been suffering from Hashimoto's for many years, shared that after following Dr. Steve’s eating plan, supplement protocol, and exercise suggestions, most symptoms disappeared without medication. They lost 30 pounds in six months, and their acid reflux, joint pain, and headaches nearly vanished. This marked a major improvement after feeling horrible and skeptical for a long time.

Another patient reported that Dr. Steve’s extensive testing uncovered underlying issues like candida, unbalanced hormones, vitamin deficiencies, and toxins. Treatment with natural medicines helped treat these problems effectively, avoiding crazy prescriptions. They expressed high appreciation for Dr. Steve’s detailed research and genuine care.

A third patient praised Dr. Steve’s chiropractic adjustments, noting a remarkable reduction in lower back pain that affected their leg. They appreciated his clear explanations and level of care, leaving each session feeling much better.

Overall, the center provides personalized, natural healthcare that has helped many improve their health and well-being.

I had a great experience with Dr. Steve Hyjek. I had lower back pain for years, and after just one treatment, I felt significant relief.

He performed a very thorough and detailed examination and truly understood the root cause of my pain.

Highly professional and knowledgeable—I strongly recommend him to everyone.
