Discover Healthy Aging with Pure Longevity

Traditional healthcare is failing us when it comes to maintaining health and vitality as we age. By treating disease after it has already started, we are increasing lifespan while decreasing quality of life. Pure Longevity is here to change that.

Our goal is to help you avoid disease and injury altogether, so that you can live a long, active, and healthy life. Armed with the latest advances from the fields of longevity and lifestyle medicine, our doctors use evidence-based testing to identify your personal long-term risk factors and recommend interventions that you can take now to optimize your current and future health.

Body composition and fitness testing provide an in-depth look at your physical and metabolic health.

Make changes decades before disease starts with specific lifestyle, dietary, fitness, and medical recommendations based on your results.

How It Compares

Conventional Medicine vs Pure Longevity

Proactive healthcare has the power to transform the way we think about aging.

Conventional Healthcare

Intervention limited to patients with specific signs that indicate a 10% or greater risk of a heart attack or stroke within the next 10 years.
Most early testing is dismissed as unnecessary.
Fitness is not prioritized for long term health.
Goal is to stabilize cardiovascular disease once it is found.

Pure Longevity

Intervention appropriate for any patient with a heightented lifetime risk of heart attack or stroke.
Early testing has a massive impact on lowering your long term risk.
Fitness is the primary way to achieve cardiovascular health and longevity.
Goal is to completely avoid cardiovascular disease if possible, or at least significantly delay it's onset.

In Depth Program Information

Advanced Lipid and Apolipoprotein Testing delves deeper than your good and bad cholesterol, proving a comprehensive look at your current and long term genetic risk of developing heart disease.
Advanced CT imaging looks for pre-clinical plaques that may indicate you have hidden signs of early heart disease.
VO₂ Max Testing gauges your current cardiovascular abilities and how your body utilizes nutrients, providing a path to maintaining and improving heart health and physical and metabolic fitness into your advanced age.
Early Lifestyle Interventions and Treatment are possible based on your test results, from earlier usage of statin medication, to diet and exercise plans, and even novel therapies such as a sauna routine.

Conventional Healthcare

Screening limited to obese patients over 40 years old.
A1C considered sufficient screening.
No intervention recommended until diabetes is diagnosed.
Goal is to prolong life and decrease complications of diabetes.

Pure Longevity

Every patient is screened.
Insulin, glucose, and inflammatory markers are checked.
Intervention recommended at the pre-diabetic level or earlier.
Goal is to completely prevent diabetes, heart disease, and cancer.

In Depth Program Information

Full Biochemical Testing evaluates organ function, checks for evidence-based inflammatory markers, and looks for early evidence of diabetes and other metabolic or inflammatory disorders.
Continuous Glucose Monitoring allows you to see the immediate effects of your diet and lifestyle choices on your blood sugar, empowering you to make immediate changes, and helping us gauge your current and future risk for diabetes and other metabolic diseases.
Comprehensive Insulin Panel determines how effectively your cells are responding to insulin, which can affect your risk of numerous disorders including many cancers.
Recommendations can include early use of metformin and other medications, lifestyle modifications such as diet change and stress management, and Zone 2 cardiovascular training to improve cellular mitochondrial density and support a healthier metabolism.

Conventional Healthcare

Alzheimer's and dementia preventive screening is not common.
Pre-emptive intervention for neurodegenerative disease is not done.
Cancer screening, while common, is often done too late or not aggressive enough.

Pure Longevity

Your relative long term risk for Alzheimer's and dementia can be evaluated.
Improving sleep hygeine, lifelong learning, and temperature therapry are explored as preventive options for neurodegenerative disease.
Advanced early cancer screening can be appropriate for certain patients.

In Depth Program Information

Galleri Testing uses advanced DNA detection combined with advances in AI to detect DNA linked to cancer before you could otherwise detect it clinically (optional add-on test).
Genetic Evaluation looks at common genetic biomarkers such as APOE to determine your relative risk of developing neurodegenerative disease as you age.
Other Aggressive Early Screening Recommendations are discussed to help detect cancer earlier than standard medical recommendations. For many patients, earlier colonoscopies and/or mammograms and even MRIs may be recommended.
Lifestyle Recommendations including sleep, continuous learning, and temperature therapy are explored to reduce your risk of certain debilitating diseases.

Actionable Recommendations

Early Medical Treatment and Supplementation
High risk patients may benefit from early statin usage or metformin to help them entirely avoid heart disease or diabetes. Novel therapies such as rapamycin, PCSK9 inhibitors, and more can be explored to slow down disease and the process of aging. We may recommend long term medications to discuss with your PCP based on the results of your testing.
Specific Diet and Exercise Recommendations
When we intervene before disease starts, lifestyle changes can be used as a very effective treatment. Nutritional recommendations such as diet changes or intermittent fasting, and fitness routines such as a focus on strength training or Zone 2 cardiovascular training are all considerations to help reduce your specific risk factors.
Aggressive Screening, Alternative Therapies, and More
Your results may indicate that earlier screening tests are appropriate, or that cold water immersion therapy might reduce your risks of long-term disease. Some patients might need to prioritize sleep above all else. Armed with a personal toolkit of information, we can make specific recommendations that will actually make a difference in your life.

Rebecca Bub, DO

Owner of Pure Family Medicine
Board Certified Family Medicine Physician
Special Interest in Longevity and Lifestyle Medicine

Dr. Rebecca Bub has always felt that traditional healthcare waits too long to intevene and is stuck managing disease rather than truly preventing it. When she opened Pure Family Medicine, she was free to practice her way and immediately saw amazing results for her patients. From preventing diabetic patients from needing insulin through close monitoring and lifestyle changes, to early intervention for subclinical cardiovascular disease, taking the time to connect with patients and do things differently made a huge difference.

Dr. Bub's career-long interest in improving long term health and vitality through preventive care and lifestyle changes led her to create Pure Longevity. Her approach mirrors advice popularized by recognized health and longevity authorities such as Dr. Peter Attia and his book Outlive, Dr. Andrew Huberman and his popular Huberman Lab podcast, and others.

Optional Add-On Testing

Galleri Test (Cost is $949)

An advanced DNA test screens for over 50 cancers. Due to the expense and risk of false positives in certain patients, we will consult with you about whether this test is appropriate for you. Cost is $949.

Full Body MRI (Cost varies)

A full body MRI scan to look for early signs of disease that may be missed by traditional testing. We will consult with you on whether this test is appropriate, as it has a high risk of false positive results which may lead to further unnecessary testing. Cost varies depending on exact study type and facility.

CT Coronary Angiogram (Cost varies)

A detailed CT study of your coronary arteries. This test is very helpful in providing in-depth insight into cardiovascular disease but due to the risks associated with dye injection and radiation exposure is not appropriate for all patients. This test is typically done in a hospital setting. Cost varies depending on facility.

Not Included

Pure Longevity is a consultation service and does not provide ongoing care. Our program is meant to empower you with the knowledge and recommendations needed to make specific changes that will lead to a long and healthy life. It is not a substitute for a primary care doctor or specialist as we do not provide ongoing management, follow-up, or prescribe medication for illnesses that may be diagnosed through this program.

We strongly believe that ongoing primary care is vital to long term health. If you are looking for a PCP, Dr. Cameron is accepting new primary care patients through our direct primary care membership, or you can use the information we provide in this program to take a more proactive role with your current PCP or specialists.

Common Questions

Does Pure Longevity include follow-up care?

No, Pure Longevity is designed to be a consultation service for patients who want insight and actionable recommendations for their long term health. Many patients want to take a do-it-yourself approach and are comfortable following up when necessary with their PCP. However, we do offer long term primary care through our direct primary care membership for patients who are interested in continuing their long term wellness and longevity journey through our practice.

Will you prescribe long term medications if indicated?

Long term medications require long term follow-up, and so we do not prescribe medication as part of this program. If you decide to join our practice for ongoing primary care after your longevity program concludes, you can discuss long term medication with our doctors. If you do not join us for primary care, we will provide our recommendations that you can discuss with your PCP to make sure you get the appropriate follow-up care.

What if I decide this program is not right for me?

We require an initial payment to book your first consultation with our physicians, this payment is refundable until 48 hours prior to your consultation. If you decide to cancel within a 48 hour period before your initial consult we will refund 50% of the initial payment so that we can cover our staffing and payment processing costs. After your initial consult, if you decide not to proceed with our program there is no obligation for further payment. Once you decide to proceed with the program, the full fee is non-refundable.

What if I need additional testing during the program?

Every patient is different. While we do have a standard testing plan so that we can present a transparent and up front price, your needs may differ. During your initial consultation you and your doctor may discuss the need for modified or additional testing. If this is the case, we can bill you separately for the cost of these additional tests, with your approval.
