Endocrinology:
Sequoia Medical 360

Precision Hormone & Metabolic Care in Westchester, NY

The endocrine system is the body’s command center for energy, metabolism, reproduction, and overall vitality. Its network of glands and hormones influences nearly every organ system. When imbalances arise, the effects ripple across the body — from weight and energy levels to bone strength, cardiovascular health, and fertility.

At Sequoia Medical 360, we provide comprehensive, concierge-level endocrinology tailored to restore balance and optimize long-term health. Led by Dr. Tony Mathews, a quadruple board-certified endocrinologist with fellowship training in Preventive Cardiology and Endocrinology/Metabolism, our practice integrates advanced diagnostics, cutting-edge therapies, and personalized lifestyle medicine.

Explore the areas of endocrine care we specialize in:

Diabetes

Diabetes is more than a sugar problem — it is a complex disorder of insulin regulation that affects the entire metabolic system. At Sequoia, we manage the full spectrum, including Type 1, Type 2, gestational diabetes, and rarer forms such as MODY and Type 3c. Our care includes continuous glucose monitoring (CGM), insulin pump integration, and advanced pharmacologic therapies. Beyond glucose control, we address cardiovascular risk, kidney function, and long-term complications.

Obesity Management

Obesity is a chronic, relapsing disease shaped by hormones, genetics, and environment — not simply willpower. At Sequoia Medical 360, we go beyond calorie counts to address the root causes of weight gain and metabolic dysfunction. Our board-certified obesity medicine specialist integrates next-generation therapies — including GLP-1 and GIP receptor agonists, SGLT2 inhibitors, and tailored pharmacologic strategies — with precision nutrition frameworks, resistance and aerobic training plans, and InBody 770 body composition analysis. The result: personalized, sustainable weight loss that improves both healthspan and longevity.

Metabolic Syndrome

Many patients with prediabetes also meet criteria for metabolic syndrome — a cluster of conditions including elevated blood sugar, high blood pressure, abnormal cholesterol, and abdominal obesity. Together, these dramatically raise the risk of cardiovascular disease, stroke, fatty liver, and type 2 diabetes.

At Sequoia Medical 360, we specialize in identifying and reversing this condition through advanced diagnostics, cardiometabolic screening, body composition analysis, and personalized treatment. By addressing insulin resistance, lipid abnormalities, inflammation, and visceral fat simultaneously, we help patients not just manage risk but actively restore long-term health.

Hormonal Health

Hormones regulate energy, mood, reproduction, and vitality. Subtle shifts can lead to fatigue, weight gain, mood changes, infertility, and loss of performance. We offer specialized care for men and women, including testosterone optimization, peri-menopause and menopause support, PCOS evaluation, and fertility-focused endocrine care. Our goal is not just balance, but optimal quality of life across every stage.

Bone Health

Strong bones are the foundation of long-term vitality. Osteoporosis and calcium disorders often go unnoticed until fractures occur. We use DEXA imaging, metabolic bone panels, and advanced calcium regulation testing to identify issues early. Our therapies combine pharmacologic treatments with nutritional optimization, vitamin D balance, and exercise prescriptions to protect skeletal strength.

Thyroid Disorders

The thyroid is a small gland with far-reaching effects on metabolism, weight, energy, and cardiovascular health. We evaluate and treat hypothyroidism, hyperthyroidism, thyroid nodules, and thyroid cancer, using ultrasound imaging, antibody panels, and molecular testing when indicated. Our approach ensures treatment is precise, avoiding both over- and under-treatment.

Pituitary Disorders

As the body’s “master gland,” the pituitary regulates thyroid, adrenal, reproductive, and growth hormones. Pituitary nodules or tumors can cause hormonal imbalances that impact multiple systems. We provide detailed pituitary hormone panels, imaging coordination, and precision treatment to ensure comprehensive management

Adrenal Disorders

The adrenal glands govern stress response, blood pressure, and metabolism. Disorders such as adrenal insufficiency, hypercortisolism (Cushing’s syndrome), and adrenal-related hypertension require specialized evaluation. We deliver advanced endocrine testing, imaging review, and long-term treatment plans to restore adrenal balance and safeguard overall health

Lipid Disorders

Cholesterol and triglyceride disorders are among the most powerful drivers of cardiovascular disease. Standard lipid panels often miss key risks, which is why we go further with apoB, lipoprotein(a), particle size, and advanced lipid testing. With expertise in Preventive Cardiology and Clinical Lipidology, Dr. Mathews provides evidence-based strategies to reduce risk and optimize cardiovascular protection.
