In Harmony Health and Wellness is a functional medicine and aesthetic wellness practice located in Glendale, Arizona, founded and led by Nadia Applegate, FNP-C, FMACP, a board-certified Family Nurse Practitioner. We specialize in hormone optimization, medical weight loss, functional medicine, alcohol reduction support using the Sinclair Method, and aesthetic treatments including Botox, dermal fillers, and PDO thread lifts. We serve patients throughout Arizona via both in-person and telehealth appointments.

Your complimentary 15-minute consultation is a no-pressure conversation with our team to understand your health goals, review your concerns, and determine whether our services are a good fit for you. We'll explain what a full evaluation looks like, what to expect from your first appointment, and answer any questions you have. No medical advice or prescriptions are provided during this call. To book, request a consult via the contact us section of the website or call (480) 262-9066.

In Harmony Health and Wellness is a cash-based, direct-pay practice and does not bill insurance. This model allows us to spend more time with each patient and offer truly personalized care without the limitations of insurance protocols. Many patients find that the depth of evaluation and customized treatment they receive here is not available through insurance-based practices. We can provide a superbill upon request for potential out-of-network reimbursement — we recommend checking with your insurance provider.

We offer both options. In-person appointments are available at our Glendale, Arizona office at 6760 W. Deer Valley Rd., Suite 13. Telehealth appointments are available for most medical services — including hormone optimization, functional medicine, medical weight loss, and alcohol reduction support — for patients located anywhere in Arizona. Aesthetic treatments such as Botox, fillers, and PDO threads require an in-person visit.

Functional medicine is a root-cause approach to healthcare that looks at how your hormones, metabolism, gut health, nutrition, genetics, and lifestyle interact — rather than simply treating individual symptoms in isolation. At In Harmony Health and Wellness, we use comprehensive lab testing and detailed health histories to identify why you feel the way you do, then create a personalized treatment plan to address those underlying causes. Patients who have been told their labs are "normal" but still feel exhausted, unwell, or dismissed often find answers through functional medicine that they couldn't get elsewhere.

We commonly support patients experiencing hormonal imbalances (including perimenopause, menopause, and low testosterone), PCOS, unexplained weight gain or difficulty losing weight, chronic fatigue, brain fog, metabolic dysfunction, insulin resistance, thyroid concerns, gut health issues, and alcohol use disorder. We also offer preventive care and healthy aging support for patients who want to optimize their health before symptoms become serious. Every care plan is individually designed — we do not use cookie-cutter protocols.

Functional medicine is a strong fit if you are tired of being told your labs are normal when you don't feel normal, have been managing symptoms with medications without identifying the root cause, want an active role in your own health, or are looking for a provider who will take the time to truly listen. Our free 15-minute consultation is the easiest way to find out whether our approach aligns with your goals.

For women, we offer comprehensive hormonal evaluation and management including estrogen, progesterone, and testosterone optimization, thyroid assessment, adrenal function evaluation, and support for conditions like perimenopause, menopause, PCOS, and irregular cycles. We use both bioidentical and FDA-approved hormone therapies when appropriate, always guided by thorough lab work and a complete clinical picture — not just your age or a single lab value.

For men, we offer testosterone optimization including evaluation for low testosterone (low T), fatigue, decreased libido, mood changes, muscle loss, and metabolic concerns related to hormonal decline. We perform comprehensive hormone panels and design individualized protocols that may include testosterone replacement therapy (TRT), lifestyle optimization, and nutritional support.

es — this is one of the most common reasons patients come to us. Standard lab reference ranges are designed to detect disease, not optimize function. Many patients feel significant symptoms at hormone or thyroid levels that fall within the "normal" range. At In Harmony Health and Wellness, we interpret labs in the context of your symptoms, your history, and functional optimal ranges — not just whether a number falls within a broad population average. We frequently find treatable imbalances that have been overlooked.

Our medical weight loss program addresses the root causes of weight resistance — including hormonal imbalances, insulin resistance, thyroid dysfunction, metabolic adaptation, and inflammation — rather than focusing on willpower or calorie restriction alone. When clinically appropriate, we may incorporate GLP-1 medications (such as semaglutide or tirzepatide) alongside nutritional guidance, lifestyle strategies, and metabolic support. Every program is individualized based on your labs, history, and goals.

Yes. When medically appropriate, we prescribe GLP-1 receptor agonist medications as part of a comprehensive weight loss plan. These medications work best when combined with nutritional support, metabolic optimization, and lifestyle changes — which is exactly how we approach them. A full medical evaluation is required before any prescription is provided.

Weight resistance is rarely about effort. It is frequently driven by underlying hormonal imbalances (low thyroid, insulin resistance, cortisol dysregulation, low estrogen or testosterone), metabolic adaptation, poor sleep, or gut health issues. These are the factors we evaluate and treat. If you've done "everything right" and your body isn't responding, a functional medicine evaluation can identify what's actually standing in the way.

We offer Botox® and Xeomin® neurotoxin injectables, dermal fillers for lips and cheeks, and PDO lifting thread treatments. All aesthetic services are performed in-person at our Glendale office by Nadia Applegate, FNP-C, FMACP. We take a conservative, natural-enhancement approach — our goal is for you to look refreshed and like the best version of yourself, not overdone.

A PDO (polydioxanone) thread lift uses dissolvable medical-grade sutures to physically lift and tighten sagging skin — most commonly in the face, jowls, neck, and brows — without surgery, significant downtime, or scarring. It's an excellent option for patients who want visible structural lifting that goes beyond what injectables alone can achieve. Candidacy depends on skin laxity, anatomy, and goals, which we assess during an in-person consultation. Pricing starts at $1,200.

The Sinclair Method (TSM) is an evidence-based, FDA-approved pharmacological approach to alcohol use disorder that uses naltrexone taken before drinking to gradually reduce the neurological reward response to alcohol. Over time, this process — called pharmacological extinction — significantly reduces cravings and consumption without requiring immediate abstinence. It is one of the most effective and underutilized treatments for alcohol use disorder, with strong clinical evidence behind it. We offer TSM as part of a supportive, non-judgmental care plan.
