Client Testimonials

  • 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.

  • I am Glennis, a patient of Dr. Kelly Parcell. I started seeing Dr. Kelly in November of 2009 because I was diagnosed with Osteoporosis by my Medical Doctor. I was not anxious to go on pharmaceuticals for my Osteoporosis. I went to Dr. Kelly looking for an alternative. I met with Dr. Kelly and we discussed different avenues to pursue. I am glad to report that my Dexa scan this year is very positive, I am getting better. This has been achieved by eating plans, supplements, and continuing to stay active. The meetings with Dr. Kelly were very individualized and I felt very good about being heard. Time well spent, from a patients point of view. No questions unanswered or not discussed, and the personal support was of great value for me. I found for me, a blend of tradition medicine and naturopathic medicine was what has worked for me. Finding Dr. Kelly has been a major step in the right direction for healing my body. At the age, 63, I continue to be active, snow skiing, biking, hiking and enjoying the out doors. Life is Good!

    Thank you Dr. Kelly.

  • As has been the case over many years now, NatureMed has been able to fulfill my needs and guide me to the best practices for my ongoing health. It is a boon to have them where I live.

  • NatureMed Integrative Medicine is a beautiful synergy of doctors and staff. It is exceedingly rare that I meet doctors who really keep up with new science/technology as well as scholastic articles (and even meet with these new scientists/doctors pioneers!) AND put it to use in their treatment protocol for their patients—especially doctors who have had their degrees up on their walls for a comfortable amount of years.

    NatureMed is fully attuned to each patients’ needs and treats them with science that has long been proven as well as the newest, medicinal break-throughs for an effective blend of integrative medicine. All the doctors are available just a portal email away if anything ever comes up in between follow-ups, which is not something many practices offer and a comfort for those whose health is less stable/have longer travel times to Boulder.

  • After months of struggling with West Nile Virus, a family friend recommended us here after traditional medicine didn’t offer any treatments. AMAZING PLACE!! Everyone at this clinic is exceedingly kind, gracious, and helpful. They spend incredible amounts of time with each patient, answering any questions and concerns. The office is always spotless and clean, and IV treatments here are a breeze in the nicely appointed IV room. If traditional medicine isn’t helping you or you prefer integrative medical approach, THIS IS THE PLACE FOR YOU!!!
