Are you one of the millions suffering
from yeast infections?

You should not have to endure symptoms of yeast infections for weeks or months – or even years! – when definitive diagnostic tests, effective antiyeast treatments and preventive programs are available.

This website offers all the information you need to overcome yeast infections and related yeast allergies.

Welcome to Yeast Consulting Services!

My name is Dr. Marjorie Crandall. I am a Ph.D. microbiologist with expertise in infectious diseases. I am a Candida researcher and former Candida patient. In order to cure my own yeast problems, I started pursuing academic research on Candida in 1978. The knowledge I gained about Candida yeast infections allowed me to recover my former good health in the mid-1980s.

At that point, I realized that my unique perspective would allow me to help other patients who were suffering from chronic candidiasis. So, in 1988, I founded Yeast Consulting Services. The mission of YCS is to provide accurate information to help patients overcome yeast infections and yeast allergies. YCS offers the following products and services.

Help for patients with yeast infections

Paperback Book

OVERCOMING YEAST INFECTIONS: A Ten-Step Program of Medical Care and Self-Help for Candidiasis” was published on Amazon in March of 2023. Use this link to purchase book:

The eBook is forthcoming on Amazon. If you sign up on this website to receive Yeast Updates, you will be notified when the eBook is available for sale, and you will receive updates on current topics about yeast infections.

Registration for Yeast Updates
Sign up to receive e-mails on new information about yeast infections. Confidentiality is guaranteed. None of your information will be given or sold to others.

Phone Consult
To receive personalized support for your battle against chronic yeast infections, please prepay for a telephone consultation. When I receive your payment and email address, I will send you a yeast questionnaire to fill out about your medical history. During the consult, I will discuss your case with you, identify your risk factors for yeast infections, answer your questions, and make treatment recommendations. My consulting fee is $60 for 30 minutes and $1/min thereafter. During your consult, I Review Tests you have had. After your consult, I will be able to write a Patient Evaluation to help you obtain testing and treatment for yeast infections from your doctor and reimbursement from your health insurance.

The ten-step program of diagnostic tests, effective antiyeast treatments, and preventive steps explained in the book are effective. Read these testimonials written by people just like you who have found relief from their symptoms, and are on the road to recovery, or have been cured of their chronic yeast infections.

Physician Referrals
A list of Physician Referral Services is on this YCS website. If you go to the websites of these referral services, you can ask them to provide the names of doctors who treat yeast infections in your city in the U.S. You can also request referrals to doctors who diagnose and treat chronic  yeast infections from the websites listed for laboratories in Table 7 on page 105 of my book. However, I strongly urge patients to stay with their own personal physicians. They know your risk factors for yeast infections and your medical history. Ask for the tests recommended in my ten-step program. If they are positive, then ask for the effective anti-yeast therapies explained in my program. And don’t forget to follow antifungal prophylaxis maintenance after your symptoms resolve. I sincerely hope that you can find a doctor who will devise a treatment plan tailor-made for your individual yeast problems.
