Who We Are

The Integrative Medical Group of Irvine blends the best of conventional, naturopathic, and holistic medicine, providing comprehensive, integrative healthcare for women of all ages.

Integrative Medical Group of Irvine provide a wide range of services, including physical exams and annual women’s visits, acute and chronic care, and a full spectrum of preventive and wellness care.

Because coordinated care at one site provides the best opportunity for achieving optimal health, IMGI provides:

  • Comprehensive healthcare
  • Integrative gynecology
  • Complex disease diagnosis and management
  • Advanced testing
  • Anti-aging medicine
  • Aesthetics and skincare

We believe that…

A doctor and her patient are equal partners in health. As our patient, you should fully understand and consent to all recommended treatments.
The best treatment is the most natural, least toxic treatment. Many pharmaceuticals have terrible side effects. These powerful drugs should be last resorts, not first-line treatments.
Illnesses are usually interconnected. We want you to tell us about all of your symptoms so we can treat them together.
In many cases, the body can heal itself. Your body is designed to be healthy. If you give your body what it needs, it can usually heal all on its own.
The goal of medicine is optimal health, not tolerable illness. We want you to feel amazing.
Health is an ongoing journey. As you travel through life, we will be here for you.

Dr. Felice Gersh Interview

Dr. Gersh is the medical director of IMGI and is board-certified in Integrative Medicine and OB-GYN. She is a globally-renowned expert in women’s health and complex disease management.

Why do women live longer than men? Does the ability to bear children play a role and to what extent do evolutionary forces discriminate between men and women?

In this in-depth interview Dr. Gersh explains why she “had to unlearn” about half of everything she learned at medical school calls for a fundamental “shake-up” in the delivery of health care.

Hi, I’m Dr. Felice Gersh, an OB/GYN and Integrative Medicine physician. I’m a member of the plusOne Wellness Collective and I’m here to tell you about the new @_myplusone Vaginal Dilator Set, a unique personal wellness device that may be useful in improving vaginal flexibility and addressing symptoms associated with painful penetration and intercourse.

�Vaginal dilators can provide significant therapeutic benefits for many medical conditions that affect women of all ages. Some conditions that can be improved with vaginal dilators include postpartum vaginal atrophy and painful intercourse, involuntary vaginal wall muscle spasms known as vaginismus, and vaginal stenosis or narrowing that may develop after a vaginal tightening or prolapse surgery or radiation treatment. Additionally, vaginal anomalies, chronic vaginitis, endometriosis related painful intercourse, interstitial cystitis, and other causes of painful intercourse can all potentially benefit from the use of vaginal dilators. In my older patients, dilators may also improve vaginal thinning and narrowing due to menopause, now known as genitourinary syndrome of the menopause.

When choosing a dilator, you want a product that is easy and comfortable to use and that encourages blood flow and muscle relaxation so that the tissues can stretch while also improving muscle tone and integrity. I recommend the plusOne dilator set because it has an ergonomic, slightly curved form that follows the natural shape of the vaginal canal. There are 10 vibration settings plus a heat function, which encourages blood flow and relaxation while also building muscle tone. And it has 4 graduated sizes, so you can start with where you are and size up as you are ready.

If you are struggling with any of the conditions I’ve just described, please be sure to discuss your symptoms with your healthcare provider and consider adding a dilator set to your intimate wellness journey.

Dr Felice Gersh discusses the use of BIEST in menopausal women ...

There is a lot of energy around prescribing estriol (often as Bi-est, which is usually 80:20 estriol to estradiol) for women in menopause. I think there are some really interesting applications for estriol, primarily in situations where it could be beneficial to downregulate a woman`s immune system. But for standard Hormone Replacement Therapy, I always default to estradiol

This Sunday at 4:30PM Pacific, I`m doing an Instagram Live where I will go into more detail on my position and the data, so if you have any questions about estriol or Biest, post them in the comments and I’ll address as many of them as I can on Sunday.

And please excuse my froggy voice! I was getting over a bad case of laryngitis.

Check out my discussions of the pros and cons of estriol vs estradiol and learn why I default to estradiol for menopausal Hormone Replacement Therapy.
