As a busy mom and entrepreneur, I know how difficult it can be to stay balanced and healthy in the world we live in!   As a Naturopathic Thyroid Specialist, I strive to integrate the medicines that nature has provided us with the science of laboratory testing and analysis to help you be your most energetic and fully functioning self.   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.   This careful analysis often finds gaps in thyroid care that are not addressed in a conventional medical setting. 

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, trouble making decisions
  • 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 thyroid hormone  imbalance!  If you have been to the doctor and they say your labs are normal, but you still feel awful, this is because conventional lab testing is just not enough!   In my practice we strive to support the patient in their current state, while  also working figure out the root cause of the deficiency to prevent further worsening of your thyroid condition over time.  After a thorough investigation using a variety of testing options depending on your case, 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, compounded 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.
