Dr. Yaeger’s Story

In my junior year of high school, my father took me to his chiropractor after I began to experience lower back pain while playing football. It felt as if bolts of lightning were shooting down my legs when I tackled fellow players in certain positions. The doctor was stumped, and the orthopedist said it was just strain. If I relaxed the muscles, he said, it would go away, but I was not about to hang up my jersey.

My father’s chiropractor examined me, took some X-rays and discovered the problem. With his treatment plan, I was able to continue playing football, a sport I loved. Now, I had been to a lot of hospitals as a kid, so I didn’t really want anything to do with them, but the results I got from consulting my father’s chiropractor inspired me to pursue the same career path. I could help people and I didn’t have to be anywhere near a hospital.

In college, I traded football for weightlifting and enrolled in the sports medicine program. While helping my fellow athletes, I discovered proper eating and basic nutrition. After graduation from the National College of Chiropractic, I opened my own practice and began helping others with their health problems in the best way I knew how.


At first, I was able to see a good number of patients. Many of my patients referred their family and friends, and even a fair number of doctors added me to their recommendation list as well. I enjoyed each day, from consulting with patients on their back, neck, and/or joint pain, to diagnosing and treating their concerns. As I got further into my career however, I began to notice that a lot of my patients weren’t getting well as quickly as they had been. My treatments were getting better as my knowledge and the practice grew, but I was stumped. Why was it taking longer for my patients to heal?

After much thought, I realized that my patients had other health issues that were interfering with their treatment plans. We were becoming a sicker as a society due to the poor foods, environmental toxins, and increased stress we all faced on a daily basis. Now that I had diagnosed the problem, I needed to come up with a proper treatment plan.

Many hours of research later, I discovered Nutrition Response Testing (NRT), a way to analyze the body to determine if there is a problem and if so, what the cause(s) may be. Some of the problems I encountered included heavy metals, chemical toxicity, immune challenges, food sensitivities, and more. Rather than covering up these problems, I began to learn to treat them directly.

After implementing my new knowledge, my patients began to get better! They consistently told me how good they felt, that they were sleeping better, had more energy, and experienced better digestion. Spurred by this success, I became advanced clinically trained in the technique and have continued to expand my education and evolve my practice to continue to bring my patients relief and guaranteed results.


 Jessica Mercurio, Head Operations & Holistic Nutritionist

I have always loved helping people feel good. At the end of 10 years in the hospitality industry, I knew I needed more. I decided to take my love of yoga and become certified as a yoga teacher and a certified Theta Healer in 2015.

As my interest in anatomy and healing grew, I became certified in Massage Therapy and Proprioceptive Neuromuscular Facilitation in 2017.

Seeing these amazing modalities help so many when I was introduced to Nutrition Response Testing, I knew I had to learn more. I’m attending Bauman College will soon be graduating as a Certified Nutrition Consultant.

My work now is all about helping you to optimal health through customized programs. Programs that will help you reach goals in different areas of your life.

My programs range from remedial healing, stress management, to meal prepping and nutrition education.



I can show you what to choose when purchasing foods, label reading, understanding nutrition facts, and eating a diet filled with TRUE organic, raw, and healthy foods. I will help you choose dietary supplements to aid with digestive issues, pathogens, stressors, and much more.

For the last 3 years, I have been fortunate to work with Dr. Yaeger. I am the office coordinator and handle the front end of the office. I interact and assist all our patients with their questions and their care plans.

I can say I am loving my daily work. I find comfort in helping others; thus, my life feels fulfilling. Just in the midst of a dream, I can go home to my garden and continue to nurture myself, my partner, and my pup; finding abundance in every aspect of my life, leading to a delightful terminus.

Bianca Cevallos, Certified Massage Therapist


Graduating from Carrington College in 2009, Bianca has spent the last 7 years working for Massage envy, she has gained lots of familiarity and a love for deep tissue. 

Working with Yaeger Chiropractic & Nutrition, she will perform post-adjustment massage therapy for clients as part of a holistic approach to wellness. She likewise, continues to work some days at Massage Envy. 

Bianca loves to learn and is happy to come to a clinical setting where she can approach a new client base, exploring her gifts as a therapist!  She begins with traditional technique and works with the client to adapt the therapy to suit the needs. She has become particularly adept at “reading” the client’s body structure. Bianca is happy to perform in all types of massage from structured deep tissue to relaxation. 

She originally didn’t know that massage was right for her until she stumbled upon it, this decision has made the last 11 years very exciting and she has gained a love for the natural healing process. She had suffered from her own aches and health struggles, and when she found massage, she realized how much this modality can enable the key to optimal health. Bianca has a big heart and cares deeply for her clientele, we are so lucky to have her join our team!


Caitlyn Bryson,  Office & Nutrition Coordinator

I joined Yaeger Chiropractic after eight years in the marine industry. I have a bachelor’s degree in anthropology from the University of Oregon and a master’s degree in nutrition from the National University of Natural Medicine in Portland, Oregon. After over a decade in Oregon, I’m happy to be back home in the east bay where the sun shines even in the winter.

I played soccer in high school but a partially torn meniscus in my knee my senior year ended my soccer days. In college I learned how to sail- we raced small sailboats against other college teams and I still spend as much time as possible on the water. In racing sailboats, I found strength, confidence, joy, and lifelong friends. Sailing was a catalyst in my physical health journey too. It was the first sport I’d competed in seriously since high school, and it made me care about being fit and strong again.

I started backpacking in my mid-20s after a lifetime of camping and hiking. It was an immediate obsession and only fed my desire to be strong and healthy. Backpacking provides a place to think deeply, to live in nature, and to live life at its most simple. In 2018, I walked 1000 miles from the US-Mexico border along the Pacific Crest Trail. Backpacking is truly my happy place.

In my family, food is our love language. Many of my fondest childhood memories are centered around cooking or eating comfort foods. After college, I’d gained quite a bit of weight. What started out as learning the best way to lose weight turned into learning how to eat for overall health. I saw that by changing my diet, I could fix my achy knee and clear the acne that had plagued me since I was a teen.

In 2015 I went back to school to study nutrition. I learned how to think critically about the modern human diet and how to educate others about food and nutrition. I learned to cook with herbs and spices, and nutritious and flavorful ways to prepare food. I studied vitamins and minerals and the biochemical ways they work in our bodies. I value my education because my program balanced both cooking and science and I completed my master’s degree in 2017.

I do believe that emotional health and physical health contribute to our overall well-being. Being active has always supported both my emotional and physical health and I have learned in my studies and personal experience that adequate nutrition can support one’s emotional and physical health too. I will always encourage people to find whatever activity they enjoy and move their body, be it gentle yoga or running ultramarathons. Nutrition is so personal. What works for one person may not work for the next and it is so important for practitioners and clients to work together to create a plan that is sustainable and fits into one’s lifestyle. I am so excited to join Dr. Yaeger’s team and share my nutrition knowledge with you.
