I See Fewer People

While most docs want to see as many people as possible, I intentionally limit the number of clients we accept every month so I can keep both eyes (and ears) focused on you.

My first priority is to listen not just to your symptoms but to your “story”.  I want to know what YOU are concerned about most, and how it is affecting your quality of life, productivity and hopes and dreams.

Courtney is truly a master health Sherpa! In under a year of working with her, I’ve shed over 30 pounds after years of trying without success, increased my overall health and wellness and learned significant keys to self care which have become a daily practice. I’m deeply grateful to Courtney and remain steadfast in our ongoing work together. I could not recommend her more. Laurie G., Woodland, California

When I heard from my friend about her health Journey with Courtney, I felt I found hope. For years I have been gaining weight, having brain fog, suffering from tingles in my feet and other issues that I wanted to get to the bottom of to solve them from the root. One of the main issues I had was many moments of brain fog. I felt so embarrassed that in the middle of a conversation a word would not come through, I stop mid-sentence trying to find another word to express what I wanted to say. This was very worrying to me since I have a family history of Alzheimer disease. This was about my brain fog. But there was also my extra weight which I gain over the last 8-10 year with hormonal changes of pre menopause and menopause. When I went to my OBJYN he asked me to lose weight, when I went to mammogram the Dr. told me that I was at high risk. I tried different diets, but nothing stayed off as there was no way to really maintain what I was doing. I took on the commitment to heal my body, to understand it, to build a healthier life. With Courtney brilliance and guidance, I am now 35lb less, I have no pains in my body, no tingling, and my memory is the best it has been in years. I can carry on a conversation without the fear of forgetting words. The words flowing through and if I get stuck for a second, Coutney gave me so many tools to tune into my body to see what it’s telling me it needs. It has been, and still is a beautiful process of healing, with so much love and compassion for each moment, each and every day, for each and every lesson my body is teaching me. It has been a healing journey inside out. Courtney has taught me how to align with my body, how to give my body the information it needs to work better, she offers this and so much more with her fierce commitment to health, wisdom, love and compassion. I am excited to continue my healing journey with Courtney, knowing she has changed my life and many others that I met through her groups. Thank you Courtney for giving me hope and guiding me to a healthier life.

I have been trying to find a solution to my weight gain since going into early menopause in my 40’s … many years of yo-yo dieting. When I followed Courtney’s Metabolic Reset Program for 42 days I lost 22 lbs felt calmer, slept better, and many of my aches and pains went away. I am 65 years old and feel like 35. It taught me how to eat, what to eat, and how food is medicine. Thank you Courtney!!! I got my sexy back!!

I've been struggling with belly fat since I hit menopause. Nothing changed with what I was doing but something happened and have been frustrated with what was happening to my body. Courtney put me on a program that focused on supporting my detox and my estrogen metabolism, and I finally feel like I have my body back. I would highly recommend her practice for anyone wanting to understand what happens during menopause and how to move through it without feeling crazy.

The work I did with Courtney changed my life. Even though it’s been more than 3 years, I learned so much about what my body needed to feel good and be healthy. I was diagnosed with rheumatoid arthritis and was placed on a strong medicine. But after learning from Courtney I changed my food choices and significantly reduce the inflammation in my body. I’m off those medications and feel terrific. I’ve also lost 50 lbs. and have kept it off. Working with Courtney is a wonderful investment in your health…I highly recommend her.
