The Practice
Extend Medical is the independent private precision and longevity medicine practice of Dr. Christina Paul, a board-certified internal medicine physician (American Board of Internal Medicine; Royal College of Physicians and Surgeons of Canada), based in Atlanta, Georgia.
Extend Medical is an independent private practice. Consultations are by video across all 50 states. People who live outside the United States can still apply, and whether or how that can proceed is confirmed after you submit. Care is private-pay and is not billed through insurance. Visits are unhurried, with follow-up between them. Dr. Paul can work alongside your primary care physician and specialists, and coordinate with them. The practice does not provide urgent or emergency care. Care starts with the Work with Dr. Paul form, and Dr. Paul reviews every inquiry personally.
It is built for adults with persistent symptoms and results that have been called normal, for adults managing several conditions or medications across specialists who want one physician holding the whole picture, and for adults who feel well and want to stay ahead of disease. It is not for emergencies, same-day sick visits, or the care of children.

Questions People Ask
Yes. Extend Medical is an independent private practice. Care is private-pay and is not billed through insurance. Program details are shared after you submit an inquiry.
No. Dr. Paul can work alongside your primary care physician and specialists, and coordinate with them so everyone stays aligned, while she takes on the deep investigation, the root-cause work and the ongoing optimization. Keep your primary care physician for routine and acute care.
Long enough to do the work. Visits are unhurried, with follow-up between them, and the practice keeps a small patient panel so that stays true.
It depends on the person, but there are families of markers Dr. Paul considers essential for most adults and that are not always part of a standard annual panel: a lipid picture that includes ApoB and lipoprotein(a); fasting insulin alongside glucose and HbA1c; hs-CRP as a marker of inflammation; a thyroid panel that goes beyond TSH; and the liver, kidney, iron and nutrient markers that fit your history. What follows depends on what those show and on your goals.
Learn more about advanced biomarkers →Case by case, and never as a package. Imaging such as a coronary artery calcium score or a DEXA body composition scan is considered when your history, risk and baseline results make the result likely to change the plan. Continuous glucose monitoring is used for a defined period when glucose patterns are the open question. Genetic testing is discussed when a result would change screening or treatment for you or your family. Hormone therapy is considered when symptoms and testing point the same way, with the benefits and risks reviewed with you before any decision. The test serves the thinking, not the other way around.
Yes, where it helps. With your permission, Dr. Paul can share her assessment and plan with your primary care physician and specialists, and ask for their records where they change the picture. When a specialist referral is the right next step, she says so and refers you.
Consultations are by video across all 50 states. People who live outside the United States can still apply, and whether or how that can proceed is confirmed after you submit.
Yes. Perimenopause and menopause are part of Dr. Paul's internal medicine practice, assessed alongside thyroid, metabolic and sleep factors rather than in isolation. Her board certification is in internal medicine, through the American Board of Internal Medicine and the Royal College of Physicians and Surgeons of Canada.
How she approaches hormonal health →Yes. Results you bring, including from a lab membership, a whole-body MRI, a wearable or a genetic test, are reviewed as part of your care and read in the context of your history, your other results and your goals, rather than as a report on its own. Where something needs confirming or a next test, she orders it.
Partly yes, in the sense most people mean it. Dr. Paul looks for why a symptom is happening, across hormonal, metabolic, inflammatory, gut and nutrient systems, rather than managing it in isolation. She is a board-certified internal medicine physician with training in functional, integrative and longevity medicine, so that investigation comes with physician-level clinical rigor: testing chosen to answer a question, results read against your full history, and a plan she is accountable for.
