As a busy mom and small business owner, I know how difficult it can be to stay balanced and healthy in this toxic world. As a Naturopathic Physician, I strive to integrate the medicines that nature has provided us with the science of laboratory testing and analysis. In my practice, I review lab work from a functional, not disease-based perspective, to help my patients to achieve optimal health before chronic disease occurs. 

Are you suffering from any of these?

  • Fatigue/lethargy/insomnia
  • Weight gain or inability to maintain a healthy weight
  • Foggy thinking or poor memory
  • Low libido, low vitality, low muscle tone
  • Depression, anxiety, irritability
  • Dry skin, hair, or nails
  • Body pain, joint stiffness, exercise intolerance
  • Your labs are "normal," but you do not feel normal!

If you have more than one of the above, you may have a hormonal deficiency or imbalance! If you have been to the doctor and they say your labs are normal, but you still feel awful, they may be missing the complete picture! I look at labs from a functional perspective and often find markers for issues that would otherwise go completely unnoticed!  After a thorough investigation, I use this information to create a customized program just for you, so that you can feel and look your best!   



I incorporate the use of professional grade vitamins, herbal medicine, prescription medications and homeopathy to help relieve the imbalances that often manifest as chronic disease. I also work with my patients to establish a healthy lifestyle through healthy eating, exercise, and avoidance of toxic exposures in their everyday lives. If you would like to reclaim the vitality that you've lost over the years, this is the place to start! Click here to read more about my practice and areas of expertise.
