Our Differences and Our Promises

The human body is not designed to last forever. But what if, instead of just letting things happen to your body, you could take control of it, could make it work better, so you could get the most out of every single day?

Since 2006, The Hormone Zone has been offering elite concierge health services and comprehensive naturopathic care to patients in and around the Valley, long before many of our competitors. While other clinics have been trying to catch up to the benefits of longevity medicine and alternative treatments, we’ve been perfecting our medical protocols and expanding our offerings. After almost two decades of watching imitators come and go, we are still the first and the best at providing proven, effective therapies for helping you look, feel, and function better than you have in years.

Led by renowned hormone specialists Dr. Cristina Romero-Bosch and Dr. John Robinson, the team at The Hormone Zone understands that, for your best health, you need cutting-edge solutions, not cookie-cutter ones.


As early adopters of treatment options like the O Shot, the P Shot, and peptide therapy, we’ve been at the forefront of alternative and natural treatment modalities long before they became a trend. We’re one of the few original providers of the now-ubiquitous subcutaneous hormone replacement pellet therapy, and we are constantly seeking effective and innovative ways to help our patients experience the best possible outcomes. Our clinically proven treatments are carefully researched and implemented, tailored to your unique needs and designed to help your body work the way it was meant to.

Drs. Romero-Bosch and Robinson have more than 34 years of combined experience in:

  • Hormone Replacement Therapy
  • Bioidentical Hormone Replacement Therapy
  • Thyroid disorders and disease, including hypothyroidism (low thyroid), hyperthyroidism (high thyroid), and autoimmune thyroid disease, or Hashimoto’s Disease
  • Sexual wellness, including erectile dysfunction and hormone disorders

The Promise of Potential

For the expert physicians at The Hormone Zone, the pursuit of better health isn’t a fad—it’s fundamental for a happier, more successful life. What’s more, we believe true, sustainable health happens from within, at the cellular level. Our comprehensive approach to longevity and wellness is based on a holistic perspective and driven by data, with in-depth testing, leading-edge diagnostics, and advanced analysis that goes beyond the standard to provide you with a deeper understanding of your health.

Your body works best when all of its systems are working efficiently, effectively, and in sync. Instead of treating individual symptoms you may be experiencing, we work to identify the root causes of your condition and address multiple areas of dysfunction or imbalance simultaneously with complementary therapies designed to enhance and optimize results. From gastrointestinal wellness and advanced hormone balancing to longevity and anti-aging medicine, we do more than simply offer effective treatments; we know how to coax even better outcomes from already proven solutions.

The Hormone Zone combines the best in traditional and naturopathic medicine to help treat all areas of health and wellness, such as:

  • Hormone regulation and optimization, including testosterone replacement and human growth hormone (HGH) optimization
  • Sexual wellness for men and women
  • Aesthetic medicine
  • Regenerative injection therapy (in partnership with Regenezone)
  • Thyroid health
  • Nutritional IVs and injectables
  • Weight loss
  • Adrenal health
  • Insulin imbalance
  • Metabolism support
  • Gut health
  • Brain and cognitive health
  • Cellular and DNA repair

The Value of Quality

After decades in the wellness and longevity sphere and helping thousands of patients meet and exceed their health goals, we’ve learned that optimal health doesn’t have a price tag and the value of a happier, fuller life doesn’t have a dollar sign. At The Hormone Zone, we offer elite treatments and therapies of uncompromising quality that can be life-changing, with returns that can’t be measured and rewards that more than outweigh the costs.

That’s why we keep our value proposition simple and straightforward—no gimmicky flash sales, no group discounts for subpar products or services, no coupons for generic or impersonal care. At The Hormone Zone, our pricing is designed to provide exceptional support with the most advanced technology and techniques available. We don’t cut clinical corners and we keep our team small, so you always have immediate and direct access to some of the best physicians in the country.

We also streamline your experience by not wasting valuable time tied up with insurance companies, the majority of which will, at best, complicate the reimbursement process for the type of advanced and specialized care we offer, or, at worst, outright deny it, holding your optimal health potential hostage. So while we do provide you with a detailed super bill with diagnosis codes just in case, foregoing the insurance hassle allows you the flexibility and freedom to make the medical decisions that are right for you the moment you’re ready to make them.

Discover a Different Approach at The Hormone Zone

For many people, the traditional model of medicine simply isn’t working; it isn’t meeting your needs, and it isn’t improving your life. However, to whom you entrust your health matters, and it’s important to choose wisely. Start-up and corporate clinics are a dime a dozen these days, delivering false promises and unsatisfactory care. At The Hormone Zone, our board-certified doctors are trained in naturopathic medicine and members of the American Academy of Anti-Aging Medicine, the country’s leading medical authority on the most advanced ways to improve health. Our physicians and specialists keep pace with the best medical science has to offer and are committed to maintaining the integrity of their patient-doctor relationships.

If you aren’t ready to settle for “good enough,” schedule a no-obligation consultation with the doctors at The Hormone Zone. Rediscover the energy, vitality, and verve of your youth and start living the life you were meant to live.
