Schedule a Symptom Relief Strategy Session!

Want help to survive and thrive during your midlife transition? Work one-on-one with Dr. Mache from anywhere in the world to get a personalized plan to help you start feeling better and improve your most challenging symptoms. Visit to schedule a free Symptom Relief strategy session to help you live the life you want to live.


Dr. Mache works with you via phone or Skype to:

  • Create a crystal clear vision for the kind of relief you’d like to achieve
  • Uncover hidden challenges that could be sabotaging your success feeling better
  • Know what you need to say and do to feel better and live better so you can work with your local doctor

Dr. Mache offers both one-time coaching that lasts 60-90 minutes, and ongoing coaching in 3 to 6 months blocks because perimenopause and menopause symptoms last a while. This allows time to work through your most challenging issues and develop a personal strategy that works for you.

The coaching relationship is different from a doctor-patient relationship. Dr. Mache does not prescribe medication such as hormones over the phone because he has not seen you personally as a patient and performed a complete exam and workup. But he spends the time you need to share his extensive knowledge and experience with you. You’ll be able to bridge the gap between you and your local healthcare provider. You’ll know what things to do and say when you visit your local doctor so you won’t be afraid or confused.

Please take a few moments to fill out the online application and questionnaire so we can get to know you better. If coaching seems like a good choice for you, we’ll recommend a FREE 20-minute strategy session where we can discuss the areas that need support and what your next steps would be.

“Dr. Mache served as an expert on my company’s behalf in a legal proceeding in which we prevailed. The judge noted in his decision that Dr. Mache’s testimony was more credible and persuasive than the opposition’s medical expert. Dr. Mache did this by being thoroughly prepared and reasonable in his positions. He also happens to come across as honest, likeable and can explain complex ideas well.”

I read Dr. Seibel’s book, “The Estrogen Window” at the insistence of a Doctor I work with. I was in full menopause, and confused about what to do next. The book was straightforward and very educational, explaining how hormone replacement therapy can benefit women in my situation on many levels. The book explained in an easy to read format what the true facts are about the safety and risks of hormone replacement. My experience was enhanced by the opportunity to have a phone consult with Dr. Seibel. He reviewed my medications, and history, and was able to advise me on my whole system, not just one issue. I decided to begin hormone replacement therapy. Dr. Seibel told me what to look out for with follow up tests, (based on my complete list of medications) dosing, and how to use my new prescriptions most effectively. I was greatly comforted by Dr. Seibel’s responsiveness and guidance, since he’s a renowned expert in his field. I would highly recommend Dr. Seibel to any woman trying to gain more clarity on managing this confusing, but workable period of life.
