States with BioBalance Health Patients

Dr. Kathy Maupin MD and Dr. Rachel Sullivan are leading experts in Bio-identical testosterone pellet hormone replacement, and in treating the symptoms of aging.  Dr. Maupin is the author of “The Secret Female Hormone“, the seminal work about testosterone replacement therapy for women, and “Got Testosterone?” the award winning book about testosterone pellet replacement in aging men.

The headquarters for BioBalance Health® is located in St. Louis MO, and has an office in Kansas City, MO.  People travel from all over the United States and several other countries to become a BioBalance Health patient.  Drs Maupin, Sullivan, and their staff are dedicated to providing personalized care and have extensive knowledge in bio-identical hormone replacement therapy for both men and women.

BioBalance Health addresses the symptoms of aging with an Individualized Treatment Plan for each patient.  We combine replacement of deficient sex hormones with medical weight loss, nutrition, lifestyle changes to reverse the symptoms of aging, and prevent the diseases that follow. We use bio-identical testosterone and or estradiol pellets to replace the hormones that are lost as a result of getting older.

Our patients are treated with bio-identical testosterone pellet replacement, the safest and most effective delivery system available.  We have created a unique combination of treatments that incorporate replacement of all deficient hormones (estradiol, testosterone, progesterone and thyroid) in the safest way with long term effective medical weight loss, nutritional supplementation and treatment of pre-diabetes, and other diseases of aging.

If you have noticed that you feel and look older than your age, become a Biobalance Health patient and you will experience the most comprehensive one-hour physician visit, with either Dr Sullivan or Dr Maupin, that you have ever had.  At your first consultation you will be given a detailed treatment plan and will start treatment on the same day.

Come see us at one of our two offices in Missouri (St. Louis or Kansas City).
