HOW CAN FUNCTIONAL MEDICINE HELP ME?​

Based on cutting-edge science, functional medicine offers a whole new way to understand and look at chronic illnesses from diabetes to heart disease, cognitive declineautoimmune disease and skin issues, to fibromyalgia, thyroid, anxiety, digestive issues, and more. The core concept is that chronic illness is an outcome of imbalances in the key underlying physiological systems in your body. When inflammation, blood sugar imbalances, insulin resistance, oxidative stress, microbiome changes, hormonal problems, and systemic upsets occur, the body spirals out of balance.

Functional Medicine identifies and restores these imbalances, leaving the patient feeling younger, healthier, energetic, and more hopeful about the future.

WHAT IS "ADVANCED FUNCTIONAL MEDICINE"?​

Functional medicine offers a whole new way to understand and look at chronic illnesses from diabetes to heart disease; autoimmune disease and digestive issues, to chronic pain, cognitive issuesthyroid, anxiety, depression, weight gain, and more. The core concept is that chronic illness is an outcome of imbalances in the key underlying physiological systems in your body. When inflammation, blood sugar imbalances, insulin resistance, oxidative stress, hormonal problems, toxicity, and systemic upsets occur, the body spirals out of balance. 

We use a unique clinical approach with this.  We run diagnostics typically not used conventionally that find the root cause of the issues creating symptoms. 

We then take a more natural approach to restore balance within the body through nutrition, dietary changes, and supplements.  Patients feel remarkably better, unlike the way they feel when they are merely given chemical drugs by their traditional doctors.

 

AT OUR CLINIC HEALTH IS BEING RESTORED!​

  • Patients are feeling years younger.

  • Medications are rapidly being eliminated.

  • Blood chemistry tests are normalizing.

  • Hormones are being balanced.

  • Stubborn weight is coming off.

  • Energy levels are being dramatically improved.

  • Pain and inflammation are reduced and resolved.

  • Brain fog is lifted.

  • Mental clarity returns.

  • Sleep difficulties are improved.

Dr. Victor was drawn to the success of the Functional Medicine healthcare model at Advanced Functional Medicine.

Sara Leckman, BSN, RN, HHC

 

Sara is a Registered Nurse and Board-Certified Health and Wellness Coach originally from Washington State where she completed her Bachelor’s degree in the Science of Nursing at Seattle Pacific University. Before joining the team at Advance Functional Medicine, Sara worked as a Nurse Clinician at a Community Health Clinic in Seattle, where she practiced chronic disease management and led diabetes education programs. Early on in her career, she recognized that the conventional-medicine model fails to identify and treat the root-cause of disease, and often leaves patients desperate for more help. Sara decided that she could no longer be a part of the ineffective and costly medical system that simply “manages chronic disease”. In search of something greater, Sara discovered the power of Functional Medicine. Since then, Sara has completed additional training in Nutrition, Holistic Nursing and Functional Medicine.

Sara believes the human body is innately intelligent and fully capable of healing given the right environment. As an RN Health Coach, Sara sees her patients as active-participants in their care, as they are supported in creating lasting-lifestyle change. Sara’s mission is to educate and empower patients to take back control of their health. What Sara loves most about her role here at Advanced Functional Medicine, is seeing patients get off numerous prescription medications while they continue to reverse disease and live more fulfilling lives.

Dr. Kris Larson, MSOM, DACM

 

Dr. Kris has a masters in Oriental Medicine, and is a Doctor of Acupuncture and Chinese Medicine. Her journey towards becoming a medical professional was an uncommon one. She started having her own personal health struggles in her early twenties- nagging, unexplained symptoms that would not go away.  After several years, she finally turned to alternative and natural forms of medicine for healing, and like many, her life was forever changed!  This started her journey of becoming a doctor that could fully embrace the patient, healing from the inside-out- breaking the confines of the traditional drug-therapy model.

 

She is passionate about Functional Medicine by helping patients heal through nutrition, supplements, modalities like acupuncture and a positive mind-set. She is a believer that educating and empowering her patients to live a more clean, non-toxic lifestyle combined with healthy eating can be the key foundations to optimal health and aging.
