Jennifer is a board-certified Family Nurse Practitioner with over 28 years of dedicated experience in healthcare. She began her nursing career by earning a diploma in registered nursing from St. Vincent Health Center School of Nursing in Erie, Pennsylvania. She later pursued advanced education at Chamberlain University in Addison, Illinois, where she graduated with high distinction, earning both a Bachelor of Science in Nursing (BSN) and a Master of Science in Nursing (MSN).
Jennifer's clinical expertise spans Family Practice, Otolaryngology, and Functional Medicine, with a particular emphasis on hormone optimization for men and women, treatment of thyroid conditions, and sustainable weight management. She is an active member of the American Academy of Anti-Aging Medicine (A4M), reflecting her commitment to innovative, proactive approaches to longevity and wellness. She has worked along side and trained with some of the leaders in functional medicine since the early 2000's.

Her primary mission is to empower individuals to achieve optimal well-being and enhance their overall quality of life.
Outside the clinic, Jennifer cherishes time with her two beloved dogs, Mabel and Penny. She and her husband are passionate world travelers, delighting in new cultures and the beauty of God’s creation. As a devoted mother and "Gigi" (cooler than a Grandma), she finds great joy in family moments and experiencing the world through her grandchildren's eyes.
Expert Telehealth Care for Hormones & Wellness
C3 Contemporary Care Clinic treats hormone and wellness conditions via telehealth, providing personalized functional medicine from the comfort of your home.
The C3 HINGES Framework
A Root Cause Functional Approach
H — Hormones
We evaluate your endocrine system, including thyroid, adrenal, and sex hormones, to identify imbalances that often manifest as persistent fatigue, weight changes, and mood shifts.
I — Infections & Inflammation
Chronic oxidative stress and hidden inflammatory triggers or underlying low-grade infections can drain your energy reserves. We investigate systemic inflammation markers to get to the root cause.
N — Nutrients
Essential vitamins, minerals, and amino acids are the fuel for your mitochondria. We assess for deficiencies and optimize your nutritional status to ensure your cells have what they need to thrive.
G — Gut Health
Your gut is the center of your health. By addressing microbiome imbalances and intestinal permeability, we improve nutrient absorption and reduce systemic burdens that contribute to fatigue.
E — Environmental Exposures & Exercise
We live in a toxic and fast-paced world. We help you identify and reduce environmental exposures (such as pollutants, chemicals, and allergens) while also tailoring movement and exercise to your current capacity. The goal is to support your body’s resilience without overtaxing your system, so that activity becomes a tool for healing rather than another source of stress.
S — Sleep & Lifestyle
Foundational habits are key. We optimize your sleep hygiene, circadian rhythm, and stress management techniques to support long-term energy and restorative recovery.
Supplements & Wellness Support to Compliment your Care

Functional medicine is an approach to healthcare that focuses on identifying and addressing the root cause of disease. Each symptom or differential diagnosis may be one of many contributing factors affecting an individual’s health. At C3, we don’t just treat symptoms; we look at the complex web of interactions in your history, physiology, and lifestyle that can lead to illness.
A Partnership for Root-Cause Care

Through detailed testing and clinical insight, we aim to restore your body’s natural balance and empower you with the knowledge to manage your long-term vitality and wellness.
