Client Testimonials

  • 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.

  • 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.
