Our Clinical Staff
Our clinical team is composed of licensed nurse practitioners trained in comprehensive, physiology-based care.
Each clinician at Hygenerate practices within structured care pathways developed under the leadership of our Clinical Director. While individual providers may lead your visits, our standards of care, protocols, and treatment philosophy remain consistent across the practice.
We believe in collaborative, patient-centered medicine — combining evidence-based clinical training with deeper functional investigation when appropriate.

Julianne M. Tondreau, DNP, FNP-BC
Founder & Clinical Director
Hygenerate
Clinical Director
Julianne Tondreau is the Founder and Clinical Director of Hygenrate. She established the practice to move beyond protocol-based medicine and toward a precision, systems-driven model focused on physiologic restoration.
With over a decade of clinical experience, Julianne specializes in complex hormone regulation, metabolic dysfunction, stress physiology, and inflammatory conditions. Her work centers on identifying upstream dysregulation across thyroid, adrenal, reproductive, immune, and metabolic pathways — recognizing that these systems rarely function in isolation.
Under her leadership, Hygenrate operates as an integrated care model. All clinical pathways are structured around comprehensive evaluation, measurable response, and longitudinal monitoring — not symptom suppression.
Julianne works closely with patients who have been told their labs are “normal” but continue to feel unwell. Her approach emphasizes pattern recognition, diagnostic precision, and individualized treatment plans designed for sustainable physiologic balance.
She founded Hygenrate with a clear objective: to build a practice where data guides decisions, care is collaborative, and restoration — not temporary stimulation — is the standard.
Clinical Philosophy
Modern medicine often fragments complex physiology into isolated specialties.
​
Her work centers on regulatory networks:
-
Thyroid signaling
-
Reproductive hormone balance
-
Cortisol rhythm
-
Metabolic efficiency
-
Inflammatory burden
-
Immune activation
By evaluating how these systems interact, care becomes cohesive rather than reactive.
Treatment decisions are measured, data-informed, and continuously reassessed.
Areas of Clinical Focus
-
Hormonal restoration and bioidentical hormone therapy
-
Perimenopause and menopause support
-
Testosterone optimization
-
Insulin resistance and metabolic dysfunction
-
Chronic immune activation
-
Tick-borne illness evaluation (ILADS-informed)
-
Mold-related inflammatory patterns
-
Stress and HPA axis dysregulation
Her practice serves individuals navigating complex, multi-system presentations who seek structured, collaborative care.
Advanced Training
-
ILADS-trained in tick-borne illness evaluation
-
Mold-literate clinician
-
Advanced hormone and metabolic education
-
Ongoing continuing medical education in immune and inflammatory regulation
Her clinical model is evidence-informed and guided by pattern recognition within complex physiology.
Care Model
Patients working with Julianne can expect:
-
Comprehensive history and systems review
-
Thoughtful diagnostic strategy
-
Clear, structured treatment plans
-
Measured follow-up and longitudinal monitoring
-
Collaborative partnership
This is not protocol-driven care. It is individualized regulatory medicine.
Clinical Vision
Hygenerate was founded to create a space for measured, systems-based care — where hormones, metabolism, immune function, and stress physiology are evaluated as an integrated network rather than isolated complaints.
For Referring Providers
Referrals are welcomed for:
-
Complex hormonal cases
-
Midlife metabolic transition
-
Persistent inflammatory or immune-driven presentations
-
Tick-borne illness evaluation
-
Mold-related symptom patterns
-
Stress physiology and cortisol dysregulation
​
Coordination with primary care and specialty providers is supported when appropriate.
​
Physiologic balance is not accidental. It is structured, measurable, and restorable.
Our Clinical Team
Hygenrate’s clinical team operates within a unified, systems-based model of care led by our Clinical Director. Each provider brings specialized expertise — spanning cardiology, hospital medicine, women’s health, and functional medicine — while working within the same precision-driven framework of pattern recognition, data-guided treatment, and longitudinal monitoring.
This is not siloed care. It is collaborative, integrated medicine designed to restore physiologic balance across interconnected systems.
​
While care pathways are designed and overseen by the Clinical Director, implementation is delivered through a carefully selected clinical team trained within this model.
Each provider practices within a structured diagnostic framework — focused on pattern recognition, physiologic restoration, and measured response — rather than protocol-driven care.
This ensures continuity, consistency, and clinical depth across all patient encounters.
Alexandria Ross, FNP-C
Board Certified
Family Nurse Practitioner
With over 13 years of nursing experience and seven years as a Nurse Practitioner, Alexandria brings a broad clinical foundation spanning pediatrics, emergency medicine, and women’s health.
Her clinical focus centers on root-cause evaluation and physiologic restoration. She is particularly passionate about helping patients uncover the patterns driving fatigue, hormonal disruption, metabolic imbalance, and chronic stress-related symptoms. Alexandria approaches care through thoughtful assessment, collaborative planning, and measured follow-through — prioritizing long-term stability over short-term symptom suppression.
Within the clinic, she practices within the structured restorative model — integrating comprehensive diagnostics, individualized hormone support when appropriate, and ongoing lab-guided monitoring.
Outside of clinical practice, Alexandria values time with her family and life on their ranch, where resilience, consistency, and stewardship are lived daily — principles she also brings into patient care.
Stephanie Merica, ACNPC-AG

Board-Certified
Adult-Gerontology Acute Care Nurse Practitioner
Stephanie Merica is a board-certified Adult-Gerontology Acute Care Nurse Practitioner with over a decade of clinical experience in cardiology and hospital medicine. Her background in high-acuity care informs a disciplined, systems-based approach to prevention and long-term risk reduction.
Her clinical focus includes cardiometabolic health, inflammation, and structured metabolic optimization. She works within a data-driven framework — integrating laboratory analysis, cardiovascular risk assessment, and individualized treatment planning.
Stephanie has particular expertise in evidence-based metabolic therapies, including GLP-1–based treatment when clinically appropriate. Her approach emphasizes appropriate patient selection, safety, ongoing monitoring, and long-term sustainability rather than short-term weight loss alone.
Within the clinic’s restorative model, she prioritizes measurable outcomes, collaborative decision-making, and longitudinal care designed to reduce cardiometabolic risk and improve physiologic resilience.
