Client Testimonials

  • I want to let you know how much I appreciate your nursing and support staff. You’ve assembled such a strong team. As regular patient, I so appreciate their professionalism and willingness to go the extra mile. They are a hard-working group.

    My rather lengthy (5+ hour) Vitamin C infusion treatments mean I spend a good portion of my day with your staff, once every two weeks. The atmosphere you and your staff offer is unfailingly upbeat and positive – that’s so important for patients like me dealing with cancer or other serious conditions. I find your clinic radiates a terrific energy and I honestly look forward to my “infusion days.”

    I also want to offer kudos for Dr Clark, who is part of my Naturopathic provider team. Her commitment, patient communication and approachability make her wonderful to work with.

    No doubt the pandemic has created a new set of non-trivial headaches for you and the clinic. From a patient’s perspective, I think you and your staff are handling it all beautifully, and I thank you for that.

  • I found the pellet procedure to be less painful than a T shot. Overall, my levels feel much more stable. This was definitely an improvement over self-administering shots. The staff is the best. Love these people!

  • Dr. Beades is the first physician I’ve worked with who truly listened to me and took a holistic approach to treatment, ensuring we looked at all options – not just medicine – to improve my health. She went above and beyond to explain her recommendations and made me feel empowered as a patient. This not only helped the conditions I sought treatment for but helped me be a better advocate for myself when interacting with other clinicians.

  • Dr. Kelly is truly a life saver. She is intelligent, compassionate and really thinks outside the box. Mille merci Dr. Kelly. Gros bisous!!

  • A shout out to NatureMed Clinic, Doctor Kelly Parcell and her amazing staff. For those of you in the know I have been suffering with Chronic Urticaria (hives) for over a year now. I spent my 20 year anniversary in Hawaii covered in itchy hives (thinking Chicken Pox has nothing on this…) Thanksgiving and Christmas holidays ruined because by the end of each day I was covered head to toe in hives.

    It has affected my work, because I was afraid to show properties or meet with clients not knowing if I would start breaking out in hives or my lip would start to swell.

    I went to Urgent Care 2 times. Saw an allergist, endocrinologist, my regular doctor, and a gynecologist. NOT one of them had any answers. Finally I went to see Dr. Parcell last Thursday, who BTW spent 1 1/2 hours seeing me. She read through all of the lab work and notes from each doctor. Put me on a totally different medicine that wasn’t an antihistamine. Not ONE hive since. Of course its only been 4 days since I’ve been taking the medicine….but after having hives everyday to not one hive is HUGE for me.

  • When we moved to Boulder, one of the first service providers I wanted to find was a great naturopath. I hit the jackpot with Dr. Kelly Parcell and her team! She is a keen listener, an excellent diagnostician, and a highly competent and compassionate provider. I am particularly grateful for her expertise in women’s issues, particularly maintaining hormone balance and a healthy weight. I recommend Dr. Kelly Parcell and her staff to anyone looking for a health care clinician who keeps current on research, understands and treats the whole person, and is committed to continuous improvement.
