At Aven Clinic, we go beyond symptom management to uncover the underlying causes of illness by blending the science of functional medicine with holistic practices
Dr. Karolina Baker is a Board-Certified Family Medicine Physician, Emergency Medicine-trained, and an Institute for Functional Medicine Certified Provider with over 20 years of clinical experience. She has practiced across multiple healthcare systems — from emergency departments and urgent care centers to primary care practices and mental health facilities — in the USA, England, The Netherlands, Aruba, and Poland.
Early in her career as an Emergency Physician, Dr. Baker quickly recognized the limits of conventional medicine in treating chronic illness. While acute conditions could be stabilized in minutes, patients suffering from long-term, complex diseases often cycled back into the system with little resolution. This led her to pursue advanced training in Functional and Integrative Medicine, where she found a model focused on identifying and addressing the root causes of disease rather than managing symptoms.

We go beyond treating symptoms — we uncover root causes. Through longer visits, advanced diagnostics, and personalized plans, we empower your journey toward lasting health and vitality.
Hormones are the body’s chemical messengers. They regulate everything from energy, mood, and metabolism to sleep, sexual function, and even how your body responds to stress.
Weight gain occurs when the body stores more energy than it uses, often showing up as an increase in body fat, fluid retention, or muscle mass.
Longevity is more than just living longer—it’s about living better. It means extending the years of life spent in good health, with strong energy, sharp cognition, and resilient vitality. True longevity is the ability to not just add years to your life, but life to your years.
Menopause is a natural stage of life marking the end of a woman’s reproductive years, typically occurring between ages 45–55. It’s officially diagnosed after 12 consecutive months without a menstrual cycle.
Testosterone is the primary male sex hormone, essential for energy, muscle strength, sexual health, mood, and overall vitality. Low testosterone (Low T) occurs when levels fall below normal—most often beginning around age 40 but possible at any age.
Lyme disease and other tick-borne illnesses are infections transmitted through the bite of infected ticks. Lyme disease is the most well-known, caused by the bacterium Borrelia burgdorferi.
Fibromyalgia is a chronic health condition characterized by widespread musculoskeletal pain, fatigue, and heightened sensitivity to touch.
Mold and mycotoxin toxicity occurs when prolonged exposure to certain types of mold—or the toxins they release—creates harmful effects on the body. While mold is a natural part of the environment, certain species (like Stachybotrys, Aspergillus, and Penicillium) produce mycotoxins, toxic compounds that can accumulate in the body and disrupt immune, neurological, and hormonal systems.
Candida Related Complex (CRC) refers to a collection of symptoms that arise when Candida albicans—a type of yeast that naturally lives in the digestive tract, mouth, and genitals—grows out of balance. While Candida is usually harmless and kept in check by healthy bacteria and the immune system, overgrowth can lead to widespread symptoms throughout the body.
