At Hormone Rejuvenation Center, our mission is to educate men and women about the importance of balancing your hormones for balancing your life.

We believe that the loss of natural hormones, stress, unhealthy digestion, and build-up of toxins contribute to illness and decline. Through our unique approach, we make use of functional medicine techniques, bioidentical hormone replacement, nutrition programs, and detox programs to counteract these processes.

We will design a custom program tailored specifically to your needs. Get more energy, lose weight, and feel vibrant at any age!

Dr. Seibert is recognized nationally for her award winning bioidentical hormone research on menopause and its impact on weight gain, thyroid problems, and depression.

She graduated from National College of Natural Medicine in Portland, Oregon, the oldest naturopathic school in the country. She is a board licensed naturopathic doctor in California and Oregon. She completed an evidence-based integrative medical residency program in family practice and other specialties working with doctors at Medical College of Wisconsin, Cancer Treatment Centers of America, and Oregon’s Legacy Health Systems.

She has held numerous medical faculty positions, has appeared on several television and radio programs all focusing on healthy eating and natural bio-identical hormone balancing for men and women.

Prior to becoming a doctor, Dr. Seibert worked at The Dow Chemical Company in city and industry wastewater treatment where she learned about hormonal disrupting agents.

NOTE: Forever Health provides a directory where people like you can connect with BHRT and other physicians and innovative health practitioners. We do not provide medical advice or services directly. While BHRT and prevention are important to the physicians and health practitioners listed, each has his or her own approach to practicing medicine. So when scheduling your appointment, be sure to clarify the reason for your visit, as well as your goals for seeking out such treatment.

NOTE on Insurance: Innovative practitioners and insurance companies have long debated the importance of preventive medicine and services such as BHRT. Due to variations in coverage for novel treatment options, many practitioners will resolve this issue by providing their services on a cash-only basis. Forever Health encourages you to contact the practitioner to determine if any alternative payment options or post-visit reimbursements exist.

DISCLAIMER: Inclusion in this directory is free to practitioners and does not constitute endorsement by Forever Health. All health practitioners who appear on this list do so on the sole basis of their own expression of interest in the fields of BHRT or other integrative medicine. Forever Health does not verify the competence, professional credentials, business practices or validity of the expressed interests of these health practitioners. Forever Health makes no recommendation of any health practitioner on this list and makes no suggestion that any such health practitioner will cure, treat, or prevent any disease or condition.
