Thrive Natural Medicine
From the first moment I walked into Thrive, I could feel that I was in a different kind of doctor's office. The doctors who own the practice are gracious and knowledgable, and all of the healers with whom I have interacted there are equally skilled. I can't imagine looking for healing support in any other medical office now, there really is no comparison.

I had high hopes for Thrive. Didn't work out. Way too expensive and their approach and policies are too dogmatic. I can't recommend them.

Dr. Carlos Rios is an amazing doctor. Recently I had COVID really bad and suffering from post covid syndrome for the last 5 months. His treatment plan has changed my life with all the vitamin shots + IV & peptide shots. He has also helped my with a treatment plan for an infectious disease that took about a year to get better. Will always recommend him to all patients suffering from illness. He also does a happy hour with b12 shots that is a nice boost of energy when you're real tired from the day to day stuff.

Very nice people but literally requested an IV drip for dehydration (normally costs around $150), they quotes $180. After some conversations and recommendations on vitamins etc the final bill was $450!!!

$150 new patient consultation (never asked for this or was told about this) which still leaves another $120 which was never explained.

Please just do your work and have some integrity around charges...

Nice people but I called asking for an IV drip for dehydration (normally $150 give or take). Once I finished they charged me $450!!! Breakdown: $189. For The IV, $150 entrance interview and about $110 which could never really be explained.
I know times are tough and I tip like crazy these days but come on. Any medical advice or suggestions just lost all credibility with me.

Dr. Rios and the staff at Thrive literally saved my life!!! (22F, no preexisting conditions)
2 years ago my mom passed away and it was very traumatic and unexpected. I saw my PCP and was put on a series of different antidepressants. After trying a sample pack of a new prescription drug, I woke up a few days into the treatment in EXTREME PAIN. My entire body was sore and I could not stand straight due to the stiffness in my legs. This ended up progressing to the point where I needed assistance bathing and had to use a cane due to constantly collapsing from the weakness in my body. My PCP said it

I went in for a consultation because I was (and am) experiencing digestive issues. I was diagnosed with Diagnosis A and told to purchase several supplements accordingly.
Later in the week, I was able to receive a second opinion, and based on some blood, breath, etc. tests, Diagnosis A was cleared by the second practitioner (not at Thrive).
I have been trying to contact Thrive about this, as two of the supplements prescribed could have had a very bad outcome if I had taken them. They have not answered any of my messages, through the website, email, or phone.

This is a great place for the ones of us that don't fully believe in Western Medicine. Many times due to stress and mal absorbtion I ended up with B-12 vitamin deficiency. Here they offer this vitamin in injectable form which I was having a hard time finding in this area. They can also add other vitamins to your B-12 shot for an added boost. I tried the "mood" boost and truly felt great all day and all week to be honest. I am excited to come back and try their other homeopathic combos such as the "Skin Glow". Let me not forget to Mention that Dr. Valero was kind and caring

I highly recommend Thrive to anyone suffering from symptoms that are keeping you from feeling whole. Where the approach of traditional doctors doesn't always look at the whole picture, at Thrive, I've always felt fully cared for and seen. Although somewhat alternative, their approach is very grounded and sound. The doctors there actually care about my life, health, and purpose. Unlike traditional medicine, they are not just trying to mask my symptoms, they are actually dedicated to helping me achieve and maintain optimal wellness. So happy to have found them!

Got my first ever B-12 shot the night before I ran the half Wharf to Wharf and I turned in my fastest mile times in 7 years! Also took 2nd in my age group. Not to mention I felt great. I'm now a believer!

So, what am I looking for in a doctor?
Someone who is holistic and natural.
Someone who listens.
Someone who is compassionate.
Someone who incorporates powerful new wellness science such as genetics and immunology.
Finally, I am a certified nutritionist. Scientific credibility is important to me.
I am so pleased to say, I found all of this with Dr. Juli Mazi!
When I first entered the Thrive office Dr. Mazi directs, I was struck with how serene the office is. I was also struck by how my intake interview with Dr.Mazi was more like a conversation. She really listened to my input, and she took

I found the place frenetic, disorganized and extremely busy. It really worked more as a B12 body mill. On top of that, the naturopathic doctor visits were extremely expensive and the supplements pricey. The lab work is not recognized by most insurances. On top of that, after bleeding a lot of money on visits, supplements and lab tests, nothing really worked for me.

I visited thrive two months ago and was hoping for some help with my thyroid. I took a huge amount of labs and was told my thyroid was in horrible shape. She put me on thyroid nature pig thyroid and a lot of vitamins
$650.00 dollars later I left with high hopes. Two weeks in I felt horrible so I called to see if this was indeed the right meds for me to be on ( strength)
She said yes and to be tested in mid Jan. I decided to get tested towards the end of January even though she then suggested in the mid feb when I called in. Thank god I did as not only did this medicine hurt my thyroid even more

I have always felt welcomed and safe, from the first moment I entered Thrive. The staff is super friendly, making me feel comfortable, even when a B-12 shot was being injected in my behind. Dr. Juli Mazi is a medical creative genius, who is a Healing Master for sure. She stopped my symbolic bleeding out. In less than a month, I am on a recovery road to wellness. I feel it. I strongly recommend the experience one can get at Thrive. Body/mind/soul balance. The kind that heals the planet.

Everyone should be using Dr.Juli Mazi as their primary care physician. i didn't know this going in, but Naturopathic Doctors have the same education (and prescription rights) as medical doctors except naturopaths have a commitment to natural healing. Meaning that Naturopaths are committed to not using the big pharma drugs that we all know and have fallen out of love with and will try to use natural methods first. No matter what your condition I guarantee Dr.Mazi can help!
My experience with Dr.Mazi began with a free 20 minute consultation. In the meeting we got to know each and made sure that

I came here on a referral from an old friend who is a ND in Los Gatos. After reading reviews, I used my own judgement and started seeing Dr. Mazi. She has helped me with my low thyroid issues and adrenals, tremendously. I cant' recommend her enough.. She listens and understands and guides you to a better health. Also doing the B12 shots there too. Very friendly office. I just wish insurance covers alternative health. But its so worth the $ spent. Thank you so much,

I went here at the request of my chiropractor, Dr. Griffin. I was hesitant as I didn't want to spend more money on my back issues. I am so glad I listened! The office is right off the freeway and easy to get to. The office staff is very friendly and directs you if you don't know what you are doing. Dr. Mazi is very down-to-earth and attentive. She recommended several supplements for my back and anti-inflammatories. The price was high, but I did it anyways. After weeks of using the supplements, my back pain went way down. With continued use, my back pain is next to nothing! I noticed

Dr Juli Mazi and the other practitioners have created a wonderful community where one can find not only great Naturopathicdoctors but also other complementary services for both mind and body.
I greatly admire Dr Juli Mazi as an integrative healer. What impresses me most is that Dr Mazi combines the latest in science with ancient healing modalities. Add to that she listens, and is compassionate and supportive. That outlook is also reflected in the Thrive clinic as whole. It is warm and welcoming like Dr. Mazi herself.

I've been going to see Dr. Juli Mazi for a series of B12 shots. At first I wasn't sure if the shots would help me, and I'm pleasantly surprised that I was wrong. I feel great, I no longer have fatigue in the morning, which probably is due to the B12 helping me get better sleep. I've gone to see Dr. Mazi 3 Fridays now for the shot, and I plan to continue because I love how I'm feeling.

Dr German was my first naturopathic doctor at Santa Cruz Naturopathic Medicine years ago. She embodies "doctor as teacher". Dr. Holly's demeanor and and approach towards health is gentle and effective. I've always found that she gave more than any doctor I'd had in the past whether it was explaining a tincture or sharing a recipe. She was absolutely worth following to Thrive and I recommend her to everyone in the Santa Cruz area.

I went for my first B12 shot last week. I noticed a sign advertising B12 and was encouraged to purchase after seeing their Groupon. Of course I verified via yelp before purchasing!

They offer $5 add-on's with B complex, Niacin, or other options. I opted to add Niacin. It was a super small needle and I felt that it was painless. The Dr. recommended to have the shots weekly for 4 weeks until the body's B vitamins are up to par. Then, come as needed. With the Group on for 4 sessions, this is a perfect match. I am excited to see how I feel after the 4th sesh.

We met with Dr. Juli Mazi and we both were very impressed. Dr. Mazi was very knowledgeable, listened carefully and was easy to talk with as we shared our health concerns with her. She analyzed our health records and test results and made a specific plan of action for each of us, which has enriched our lives. On vitamin B12 Friday, Dr. Mazi gave us B12 shots which were virtually painless and left us feeling happy and energized. At another time, we each received nutritional IV therapy tailored to meet our specific needs and we both felt fabulous afterwards. We can easily purchase other items that
