Patient Portals
When I had my first session with Oscar I was extremely impressed with his ability to identify problem areas and recommend natural protocols to address them. I was apprehensive about acupuncture, but it was just one part of many protocols he addressed, and felt so natural and easy, and it relieved pain immediately. I look forward to working with him in the future, and feel hopeful about addressing health problems adequately for the first time in years.

I have visited many acupuncturists from the US and abroad. I’m big on holistic health and alternative medicines. My case is a pretty complex auto immune condition and Oscar not only took the time to listen to me and wrap his head around what I’m going through, but he is working in cohesion with my N.M.D’s treatment And helping me in my healing journey. I’m thankful to the higher powers for letting meet and work with Oscar. This man is passionate and knows his craft. Highly recommended!

I have recommended Sierra Botanica to a number of my friends who continue to seek out Oscar’s advice and guidance towards their health. Meeting and working with Oscar Sierra continues to be one of those magic high points in my life. To find a practitioner who can guide you into your own power to engage with the ability of the body and spirit to actively and consciously participate in one’s own health and healing has been a blessing for me. I am grateful for Mr. Oscar Sierra.

Oscar and his team are truly dedicated to your wellness and health. Acupuncture, herbs, tinctures, supplements have made an enormous difference in my health in so many ways, from treating low blood pressure to helping to manage chronic pancreatitis. I highly recommend Oscar and his team.

More Data, Better Outcomes
Seeing Beneath the Surface
Most doctors only look at the tip of the iceberg - meager test results, insufficient scans, and superficial symptoms. Oscar knows that healing requires looking beneath the surface. That’s where MOJO Health comes in.
​
Together, Oscar and MOJO use 13 types of data to create a fuller picture of your health, your environment, and your cancer. This isn’t just about numbers - it’s about connecting the dots so your story makes sense.
​
By analyzing the molecular DNA of your cancer, Oscar can help predict which treatments will be effective for you in real time. He looks at deeper layers like immune function, cellular health, and inflammation to reveal the root causes of disease. And just as important, he helps prepare your body - so you can face treatment with fewer side effects and greater healing potential.
