Patient Testimonials

PLEASE consider seeing Dr. Prieto as one of her Concierge patients. She is a miracle worker!
I suffered months with arm nerve pain which I described as 7 out of 10, 24/7. I saw my GP several times, and tried chiropractic care, saw an orthopedic specialist, went for massage therapy, physical therapy, and acupuncture. I have had X-rays, a nerve conduction test, and an MRI. I have taken three different prescriptions for pain relief, all of which have raised my blood pressure, but on the positive side made the pain almost bearable.

And then I heard about Dr. Prieto. No, she doesn’t take insurance. As a result, she takes the time to really listen to you — to look at your history, to follow through. I was able to make my first appointment right away. She called me to follow up on my first treatment (a trigger point injection.) She suggested changing my medication and then followed up to see how that worked. It has been just 2 months since my first appointment, and under her care, my pain is never more than a 2 and often I don’t hurt at all!
Truly, this is a miracle.

Dr. Prieto is simply amazing. Why? Well for starters, she didn’t hesitate to see me on a holiday when I called in for an emergency! She also goes above and beyond with everything she does. She’s witty, has a caring chairside manner and fantastic personality. Fully recommended! Thanks again Dr. P!

I was at home, bedridden battling a viral infection for about a week unable rebuild my immune system to fight it off and was suffering from dehydration as I kept sweating out whatever fluids I put in. I went in a got the “Protector” IV. Within an hour of leaving I was feeling better and the next day it was like I was never sick. I cannot recommend this place enough, never again will I be fooling around with any illness I have, I’ll be coming here first thing. The staff was extremely courteous and kind to me, explaining everything thoroughly for me and took care of me the whole time. A wonderful experience start to finish, I would give more than 5 stars if I could.

One of the best medical experiences ever! I came in with a horrible stomach bug, throwing up every 30 mins. The doctor listened to me and is very educated in holistic ways of healing! She gave me customized fluids and vitamins to help with my nausea and dehydration, all for less than $200

I love Privacy so much!! Especially Doctor Prieto!! I’ve gone for aesthetics and for vitamins and had great experiences!! Recently I was in an accident and in extreme pain!! Dr. Prieto did trigger point injections and I have zero pain now!! They do so much!! Had surgery recently and needed to pick me up because I was feeling dehydrated. The list goes on and on of how amazing this place is!!

About Us

Privvy Modern Health was founded by Dr. Nerissa Prieto, a board-certified anesthesiologist with Stanford ICU fellowship training and more than 18 years caring for the Chico community. Dr. Prieto built Privvy on a standard most medspas don’t offer: she personally performs every CO2 laser treatment and every filler and neuromodulator injection herself, bringing hospital-level medical judgment to aesthetic and wellness care that’s often delegated to a nurse injector elsewhere.

Privvy has also become Chico’s only physician-led concierge medicine practice, giving patients direct access to Dr. Prieto for the kind of unhurried, relationship-based care that’s disappeared from most modern healthcare. We help patients manage everything from Crohn’s disease, Lyme disease, and long COVID to PCOS, fatigue, and menopause, restoring vitality through personalized, physician-led treatment.

But we don’t stop there, our exclusive nutrient blends, when combined with regenerative laser treatments, facial fillers, and Neurotoxins all administered by Dr. Prieto herself, ensure your skin ages beautifully. The result? A rejuvenated, radiant appearance backed by real medical credentials, not just marketing. At Privvy Modern Health, we seamlessly merge inner wellness with outer transformation.
