The Root Cause Specialist
You’re Closer to Answers Than You Think
From surviving to thriving is the shift. Many patients are told their labs are normal, yet they still feel exhausted, foggy, inflamed, or off. Being within range is not the same as being well. That in-between space has a name: the Gray Zone — when nothing is clearly wrong, yet nothing feels fully right. We look deeper, restore balance at the root, and move you beyond the gray into real vitality.

Skin & Hair Health
Hair thinning, skin inflammation, and premature aging can reflect deeper imbalances. We evaluate hormones, nutrient status, detox pathways, and inflammation to restore healthier skin and stronger hair from within.
Hormonal & Endocrine Disorders
Hormone imbalances can affect energy, weight, mood, sleep, and metabolism. Through advanced testing, we identify underlying disruptions and develop personalized strategies to restore hormonal balance and stability.
Adrenal Fatigue
Estrogen Dominance
Hypothyroidism
Irregular Menses
Menopause / Premenopause
Infertility
PMDD or PMS
Andropause

Autoimmune & Immune Conditions
Autoimmune conditions often develop from complex interactions between inflammation, gut health, toxins, and immune dysfunction. Our approach focuses on identifying triggers and calming the immune system to restore balance.

Chronic Infectious Disease
Persistent infections can contribute to fatigue, inflammation, and immune dysfunction. We evaluate underlying factors that allow infections to linger and support the body’s ability to restore immune resilience.

Infectious Conditions
Neurological & Cognitive Health
Brain fog, memory changes, and reduced focus can stem from inflammation, toxins, nutrient deficiencies, or metabolic imbalance. Our approach supports brain health by identifying and correcting these deeper contributors.
Mental Health
Mood, stress resilience, and emotional well-being are closely tied to hormones, gut health, inflammation, and neurotransmitters. We evaluate these interconnected systems to support lasting improvements in mental health.
Pain & Inflammatory Conditions
Chronic pain often reflects underlying inflammation, metabolic dysfunction, or toxic burden. Our goal is to identify these drivers and support the body’s natural ability to heal and reduce persistent discomfort.
Metabolic & Cardiovascular Health
Conditions like insulin resistance, metabolic syndrome, and cardiovascular risk often develop gradually. Advanced testing helps identify early markers so we can restore metabolic balance and protect long-term heart health.
Digestive & Gut Health
Digestive symptoms can signal deeper imbalances within the gut microbiome, immune system, or detox pathways. We focus on repairing gut function to improve digestion, immunity, and overall health.
Chronic & Multi-System Conditions
Some patients experience complex symptoms affecting multiple body systems. Our comprehensive Functional Medicine approach examines the full picture to uncover root causes and create a coordinated treatment strategy.
The Health & Vitality Method
For when you're ready to feel your best again
Phase 01 Address Metabolic Dysfunction & Inflammation
Focuses on stabilizing blood sugar, reducing inflammation, and restoring metabolic balance to improve energy, recovery, and stress response.
Phase 02 Address Gut Health
The gut regulates digestion, immunity, inflammation, and hormones, focusing on repair, nutrient absorption, and reducing internal stress signals.
Phase 03 Address Heavy Metals & Detoxification
Toxin and heavy metal exposure may cause fatigue, inflammation, and cognitive issues; this phase uses guided detoxification protocols.
Phase 04 Optimize Hormones
Focuses on optimizing hormones like testosterone, DHEA, thyroid, and cortisol to support metabolism, mood, strength, and performance.
Chelation Therapy The heart and soul of restoring wellness.
What is chelation therapy? It's a medical treatment that helps your body release toxic metals and chemicals that build up over time, often without symptoms—until they start interfering with energy, hormones, focus, and immunity.
Most patients don't know they're carrying this hidden burden. But even when nothing else is working, this is often the missing piece. Dr. Shiva Lalezar has used chelation therapy for over 20 years as part of her root-cause approach, helping patients reset what's blocking them so the rest of their treatment can finally work.
This hidden toxic burden can impact:
- Mental clarity & memory
- Immune response
- Sleep quality
- Detox and liver health
- Thyroid and adrenal function
- Hormonal balance
- Energy and mood
“People think detox means a juice cleanse. But real detox treats chemical exposures that can live in your tissues for decades.”
