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 receives fees for administrative and marketing services from practitioners who are part of the Forever Health Practitioner Network. Forever Health provides a network where people like you can connect with BHRT practitioners. We do not provide medical advice or services directly.

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.
