Longevity Medicine in California
Personalized medical care with Stephanie Daniel, DO, for long-term health, strength and clear thinking as you age.
Together, we make sense of your history, health data and priorities, and decide what your body is ready to respond to now. The result is a plan you can put into practice and adjust over time.

A plan built on priorities
Hormones, peptides, supplements and advanced testing can all be useful. How much any of them helps depends on what else your body is managing, and on what comes first.
Dr. Daniel's Longevity Hierarchy™ is her clinical framework for identifying those priorities and sequencing care. It weighs the factors that may be limiting your health and recovery alongside the foundations that support long-term function, so each step builds on the last.
Optimization sits above the hierarchy, not in place of it. As load comes down and capacity grows, therapies your body couldn’t tolerate before may become feasible, and they finally have somewhere to land.
Who it's for
- You feel reasonably well and want a physician-guided approach to staying that way.
- You're navigating perimenopause, menopause or other midlife changes and want to protect sleep, energy, cognition, bone and heart health.
- You have labs, wearable data or a regimen of supplements and treatments, and you want help knowing what matters.
- You want one physician to make sense of your labs, history and goals together.
- You value careful prioritization and a physician who follows you over time.
Already have lab results?
Many people have a detailed report from Function Health, Superpower or a similar service, with dozens of markers flagged and no physician to put it together. Bring those results to your Longevity Assessment. Dr. Daniel will interpret them in the context of your history and goals, decide what actually matters, and prioritize what to do about it.
What your longevity care includes
Assessment and prevention
The core of your care
- Your medical history, goals and current regimen
- Cardiovascular and metabolic risk assessment
- Sleep, movement, nutrition and body composition
- A written, prioritized care plan
Treatment and follow-up
Individualized over time
- Hormone therapy for perimenopause, menopause and midlife changes, when appropriate
- Weight and metabolic health, including GLP-1 medications when appropriate
- Medication and supplement review, often simplifying what you already take
- Reassessment and coordination as your needs change
Additional tools
Considered case by case
- Wearable (Oura, Whoop) and continuous glucose monitor review
- Genetic and biological age testing
- Home sleep apnea testing
- Imaging, functional testing and specialist referrals, such as coronary calcium scoring, DEXA or VO₂ max testing
- A considered opinion on other interventions you're weighing, including peptides
These tools are not a standard battery. Dr. Daniel recommends them only when the results would change your plan. Lab testing and outside diagnostics are separate costs, quoted before ordering.
Your physician
Stephanie Daniel, DO, founded her practice in 2012 and sees patients across California. She trained at Touro University College of Osteopathic Medicine and completed her residency in USC's Family Medicine Program. Before medicine, she spent three years at a Silicon Valley hedge fund, where evolutionary biology shaped the investment research and her view of the roots of disease.
Her approach brings your history, test results, priorities and response to treatment into one picture, and adjusts the plan as that picture changes. More about Dr. Daniel

Apply for a Welcome ConsultationCommon questions
- Is this "anti-aging" medicine?
- It's healthspan medicine: helping you stay strong, clear-headed and resilient as you age. No one can promise a longer life, but you can make well-informed decisions about your health.
- Do I need to be sick to start?
- No. Longevity care is for people who feel mostly well and want to stay that way.
- Do I have to join a membership after the assessment?
- No. The Longevity Assessment is available on its own. If you'd like ongoing care afterward, the Longevity Membership is an option.
- Do you offer hormone therapy?
- Yes, when it's appropriate for you. Bioidentical hormone therapy is often part of longevity care in midlife.
- Will you order biological age testing or full-body imaging for everyone?
- No. These tools are considered case by case, when the results would change your plan.
- I already have results from Function Health or Superpower. Can you use them?
- Yes. Send them before your Longevity Assessment, and Dr. Daniel will review them in advance so your visit focuses on what they mean and what to do next.
- Not sure which option fits?
- Start with the application. At your welcome consultation, Dr. Daniel will recommend the right starting point.
