Onna Lo MD

I went to Dr Onna Lo after a long period of stressful life events, mold exposure and years of overwork. I was in terrible shape and I knew it would take someone with vast knowledge of many modalities to bring me back to life. She was absolutely the right person! She got me started on a protocol that would get me feeling a bit better right away so that I could begin improving my lifestyle practices in ways that were necessary to start improving my health. Through my work with her we explored so many different aspects of my health. She takes everything into consideration in a very holistic way and is very fastidious in her work. You get the sense that she wants you to feel your best and won't give up until you do! It is rare to find a doctor with this much knowledge, interest and care for your health. I highly recommend Dr Onna Lo.

I have known Dr. Onna Lo for many years; first, as my general practitioner in another clinic 12+ years ago, and then again, all these years later as my health coach within her private practice setting at the Happy Health Institute. As my GP, Dr. Lo had truly impacted my life in a way no other doctor ever had. When she decided to follow her new career path, finding another GP to fill her shoes proved challenging and took many years for me to find someone I felt as comfortable with. Even once I did, something was still missing. When I needed to have a pretty major surgery and struggled with how to get healthy enough for it, I sought out the one doctor I had had so many years before, in hopes that with her support, I could get where I needed to be. I reached out to her, we met, and we discussed what my needs and expectations were and what Dr. Lo could help me with. We went over my health challenges and she had me get some labs done to see where I was as my starting point. Then she helped me to set up some goals, and advised me on some key elements as to how to move forward towards reaching those goals. Thus, the beginning of our journey together began. That’s one of the key words here too, “Together”, because Dr. Lo has been with me every step of the way! I met my first goals and had that surgery, but I have continued seeing Dr.Lo because good health and a happy life are an ongoing mission! Onna has the gift of listening beyond the spoken words so she is able to reel me in, keep me focused, and help me set new goals and visualize where I want to be next! She helps keep me accountable for what I do or do not do from one session to the next; reminding me where I came from, my achievements thus far, and where it is I want to be! I honestly cannot say enough wonderful things about Dr. Onna Lo. She has helped me beyond what my medical doctors, surgeons, and psychiatrist have been able to. I highly recommend her services to anyone out there like me!

I went to Onna after developing severe food intolerance after getting Covid that plagued me for 3+ years. Onna was able to help me reintroduce most foods back into my diet and exercise regularly again. Over the last year my health totally transformed.
