About Dr. Daniel Riordan
I am a primary care doctor specializing in men's health, including low testosterone replacement, advanced cardiovascular and cholesterol labs, gay men's health, and PrEP therapy.
I am fortunate to be a Naturopathic Doctor, having earned my Doctor of Naturopathic Medicine from Bastyr University and completed a residency at the Institute for Natural Medicine. This training allows me to prescribe pharmaceuticals as well as use supplements in my practice. I take pride in getting to know my patients and their unique situations. First office visits last 60 minutes, and return visits are 45 minutes, giving me the time to fully tailor treatments to your needs. This also allows me to review your lab results line by line with you, explaining each test even if the results are normal.
Please note that the only controlled substances Naturopathic Doctors can prescribe are testosterone and codeine. I cannot prescribe Adderall, Xanax, or controlled pain medications.
While mask mandates have changed, our office still requires masks to be worn in the facility.
Please be aware that our office is unable to verify insurance benefits. We recommend you contact your insurance provider directly to confirm that your provider is in-network and that you have naturopathic benefits.

I've honestly never had an experience this good in my life with the medical field. Dr Dan is a prime example of how the medical system should treat their patients. I have been Dr Dan's patient for a little more than a year now and you can tell he cares about his patients. The open conversations, discussions, and the sincere interest in helping you with any ailment is the reason he is my doctor. If you are in the market for a great doctor, look no further. Thank you, Dr Dan.

I recently visited Dr. Daniel Riordan, ND, and had an outstanding experience. He was incredibly responsive to my needs, promptly replying to my email regarding an additional test without requiring another appointment. Dr. Riordan took his time to explain the testosterone mechanism in simple, understandable terms, which I greatly appreciated.
The office environment was clean and welcoming, and the staff was friendly and efficient. My insurance coverage was accepted, and the copay was as expected. The office was aware of my appointment, and I received a reminder call beforehand, which was very helpful. I was seen by Dr. Riordan promptly, and there were no unexpected issues during my visit.
I highly recommend Dr. Riordan for his excellent bedside manner, clear communication, and dedication to patient care. I will definitely return for future visits.

Dr. Riordan made me feel very well taken care of. He gave me space to talk about my health concerns without being rushed, and he provided wonderful recommendations on treatment, both naturopathic and conventional. I really gravitate towards Dr. Riordan's naturopathic approach; it's what I've been missing in my past healthcare experiences. Having a doctor with such care for their patients is very important to me, and Dr. Riordan delivers that and more.
March 11, 2024Ian B.Verified patient
Dr. Dan is a fresh breath of air in his approach to health. He truly listens and gives good insight on how we can proceed with my care. Mainly focusing on life style changes and natural care before moving towards pharmaceutical treatment as a final decision. I'm glad to say I have found my primary care doctor and so quickly since moving to Washington.

A fantastic return to having a primary care physician. Dr. Dan was wonderful, explaining everything in deep detail, checking in with me after each topic to see if I had any questions before moving on. The patience and thoroughness makes me excited to have him as a doctor as I felt like he went above and beyond for me.

March 21, 2023Will K.Verified patient
Doctor Dan was top notch and I would highly recommend to everyone looking for a great doc. I hadn’t been to the doctor in years because I’ve been in good health and generally don’t enjoy the visit. While no health issues to speak of; I was long overdue for a check-up so made an appointment. Was a very great experience and I plan on following through with my my annual checkup going forward. Highly recommend even if you don’t line going to the doctor; I actually enjoyed the visit and plan on repeating.
March 6, 2023Sam K.Verified patient
This was my first visit to Dr. Dan. His review of my condition was very thorough. He spent over 1 hour with me. He listened carefully, took notes, typed up his recommendations, and followed up after the visit. I would recommend visiting Dr. Dan if you are looking for an alternative to traditional medicine.

Other doctors freaked me out about my cholesterol and told me here is a pill and that was pretty much it. Dr. Riordan took out a diagram and showed me how cholesterol impacts my arteries so I actually saw it and understood what is happening in my body. He then ran some advanced cholesterol labs and did an amazing job explaining what they all meant and why I needed to do something about my cholesterol. He also then gave me dietary and exercise advice that can help my cholesterol as well as reviewed a supplement and a pharmaceutical option and told me about the pro and con of each. I felt so informed and empowered. I actually feel good about taking on my cholesterol issues now instead of scared.

Great doctor! Wish I would have met him sooner. I'm always nervous going to a new doctor, but he's just so nice that you get comfortable really fast. I also appreciated that he waited about halfway through the visit to take my blood pressure. It was the first time at a doctor's office in I don't know how long that I didn't have a high blood pressure.

Dr. Riordan was an excellent listener and took the time to explain how things work, why he prefers certain methodologies and he even walked me through a particular chemical reaction that was relevant to my family history.
June 2, 2022Nick F.Verified patient
I really appreciated how he went over every lab with me instead of just saying everything looked fine. Always very thorough. I never feel rushed.
More than 1 year agoMP
Dr. Dan has helped both my husband and me exponentially. He is kind, prompt, and really takes the time you need. He looks at your case as a whole picture, not just a list of symptoms. I think the best thing was his testing options. He finds stuff that allopathic doctor's just glossed over and we actually had results!
