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.







Our Top Rated Functional Medicine Providers are proud to offer a truly integrative approach to whole body wellness.
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.

As each patient’s symptoms are unique, so is each patient’s path to hormone optimization. Most patients report some symptom resolution in as little as two to four weeks, but full optimization may take up to six months. Your journey will be customized to fit your specific needs. It takes more than one to two weeks for your hormones to get out of balance, so expect it to take time to resolve.
We accept Care Credit, all major credit cards, cash payments, and HSA.
Our plans will vary by each individual person, so we can’t determine a price range. Give us a call, and we will make a plan to suit your needs. Of course, you will know and fully understand the cost of integrative medicine, functional medicine, and other specialty treatments before you begin any of our treatment programs.
We are a functional medicine clinic, with the goal of helping men and women build sustainable and optimal health and longevity so that they can live their lives to the fullest.

We offer comprehensive functional medicine programs, weight loss programs, mental health and IV therapies to assist the body’s healing process for various types of chronic illness. Our programs are uniquely tailored to each patient and include ongoing education, meal planning, supplementation and coaching in order to maximize results.
Conventional Medicine assigns symptoms to disease names and often treats them with prescription medications. Functional medicine takes a more holistic approach to health by addressing issues at the root cause. Determining the cause of our patient’s symptoms enables lifestyle changes that will serve to prevent further suffering, helping you to achieve your long-term health goals in the process.
We don’t advocate fad diets or harmful weight loss pills. They may provide short-term results, but they can wreak havoc in the long run. Instead, we utilize PNOE metabolic testing and InBody BIA to tailor a unique weight loss approach that’s specific to your body type and includes customized meal and fitness planning, supplementation and coaching.
Our approach is personalized, with every recommendation based on detailed testing. Before adjusting your nutrition or supplementation plans, we aim to understand your body’s unique needs. We collaborate with you to establish beneficial morning and evening routines, provide guidance on nutrition, cultivate daily physical activity, and help manage stress. Our goal is to work in harmony with your body’s specific requirements for optimal health.
The details of each plan are patient-specific, but they will likely address gut health optimization, diet modifications, hormone balance, stress management, movement and exercise, toxic burden reduction, detoxification support, mitochondria support, and comprehensive lab testing.
While many of our patients begin to feel significant improvements within a few weeks of implementing their health plan, long-term improvements and habit changes may require more patience. You can’t rush the body to boost its capacity for healing. There are no shortcuts and no magic supplements. It has likely taken years, if not decades, for your current health and chronic issues to develop. Please prepare to invest a few months in our process to reverse those effects. Our most successful clients are committed, resourceful, and coachable, enabling them to make long-term diet and lifestyle changes. Keep in mind that the return on this investment is HUGE!
Yes, we do.
