Why people come here
A doctor, a dietitian, and a trainer who share one set of your numbers
Most people are running two appointments and a gym membership that never talk to each other. Here is what sits under one roof at neXendo instead.
Ten rows. Scroll inside the table to read them all.
| What you get | neXendo Wellness | Standard doctor visit | Your gym |
|---|---|---|---|
| Hormone and metabolic lab work | neXendo WellnessYesOrdered and read by an endocrinologist before any plan is written. | Standard doctor visitSometimesDepends on the visit and the reason you came in. | Your gymNoNot offered. |
| Resting metabolic rate testing | neXendo WellnessYesMeasured directly, so your calorie number comes from a test, not a formula. | Standard doctor visitNoNot part of a standard visit. | Your gymSometimesSome gyms offer it, without clinical review of the result. |
| Body composition analysis | neXendo WellnessYesBody fat, muscle mass, and how both move over time. | Standard doctor visitSometimesUsually weight and BMI only. | Your gymSometimesOften a handheld device or a smart scale. |
| Bone density scanning | neXendo WellnessYesDEXA on site in Long Island City, read in context with your labs. | Standard doctor visitSometimesReferred out, and the result often comes back without a plan attached. | Your gymNoNot offered. |
| A written plan built from your own test results | neXendo WellnessYesNutrition and training are written after the numbers come back. | Standard doctor visitSometimesAdvice in the room, rarely a document you leave with. | Your gymSometimesA workout plan, built without any of your test results. |
| Registered dietitians who work across disease states | neXendo WellnessYesOn staff, and reading the same results your doctor is. | Standard doctor visitSometimesA referral out, if the practice has someone to refer to. | Your gymNoNutrition coaching is not the same credential. |
| Supervised exercise | neXendo WellnessYesLed by our medical fitness trainers, working with your doctor. | Standard doctor visitNoYou are told to exercise, not shown how. | Your gymYesNo medical data behind the session. |
| Care for chronic conditions | neXendo WellnessYesDiabetes, thyroid, bone health, PCOS and menopause, all in one place. | Standard doctor visitYesThe medical side, with nutrition and exercise handled elsewhere. | Your gymNoNot a clinical setting. |
| Retesting, with the plan adjusted as your numbers move | neXendo WellnessYesThe plan changes when the data does. | Standard doctor visitSometimesAt the next annual, if you book one. | Your gymNoNothing clinical is being tracked. |
| Insurance, FSA and HSA, or self-pay | neXendo WellnessYesWe verify your coverage before your first visit, so you know the cost going in. | Standard doctor visitYesCovered, for the medical portion. | Your gymNoMembership and training come out of pocket. |
This compares categories of care, not any named practice or gym. What a given doctor's office or gym offers varies, and plenty do more than the middle and right columns describe.
-
One endocrinologist, four dietitians, and three medical fitness trainers, reading the same test results for the same patient. That is the whole idea.
The team works across women’s health, bone health, diabetes, and medical weight loss, with metabolic testing, body composition analysis, and labs done before any plan is written.
-
Our team consists of endocrinologists to registered dietitians, personal trainers, and social workers for a truly holistic and personalized approach to your wellbeing. We emphasize the power of food, medicine and movement.
As providers, we ultimately understand that health can be achieved with knowledge.
Knowledge about proper nutrition.
Knowledge about the importance of movement.
Knowledge about the advances in medicine.
And knowledge about the various aspects of life that impact our overall well-being.
Because we understand that so much more is vital to health.
