Heal your Gut

Optimize your health.

You deserve to live a life full of energy and vitality. However, modern American life doesn’t make healthy living easy. The cumulative impacts of eating on the run, excessive computer time, environmental pollutants, and the stress of our hectic schedules can diminish vitality and make us vulnerable to chronic health issues. Gut symptoms often signal a sense of 'dis-ease'—your body's way of alerting you to rebalance before things escalate into full-blown disease. Functional medicine offers a proactive approach to get you back on the path to wellness.

Personalized to you.

Migraine relief

Migraines and headaches don’t need to dictate your life. Functional medicine delves into the root causes of migraines, recognizing that each individual experiences them differently, with distinct triggers and underlying issues. We’ll work together to uncover what fills your 'migraine bucket'—the combination of factors that precipitate your attacks—and develop strategies to empty it, putting the brakes on this chronic cycle.

Hi there,

my name is Debora!


Are you struggling to understand why you're not feeling your best? Whether you're grappling with vague symptoms or dealing with an early diagnosis, you are in the right place! The approach needs to go beyond temporary fixes.  As a functional medicine practitioner, my goal is to identify and address the root cause of your health concerns.  Our process begins with a thorough life health review, including lab assessments, and then we work to reduce symptoms and rebalance with food, supplements, and a lifestyle plan that fits your schedule. I employ natural solutions that support all of the body's systems. When we bring balance and energy back into your life, you'll be able to get back to doing what you love with gusto! 

Although my home office is in Berkeley CA, I provide telehealth services for clients in many states. Please check my FAQ for more information.

Find Relief
from Chronic Issues

Functional medicine excels when dealing with chronic conditions. When you’re in pain, bloated, feeling low energy, or foggy, there’s often an underlying imbalance causing your discomfort. Don’t settle for symptom management. Let’s get to the root cause. 

Metabolic Health

Metabolic health is about more than just managing weight and cardiovascular risk markers—it’s about holistic well-being. As a functional medicine practitioner, I approach your metabolic health by naturally enhancing GLP-1 levels through targeted strategies aimed at rebalancing your gut microbiome. Additionally, we’ll work together to refine your diet, incorporate beneficial movement, optimize sleep patterns, reduce stress, and foster opportunities for relaxation and social connection. Each element plays a crucial role in your journey towards sustainable metabolic balance and long-term health.


Functional medicine practitioners may use advanced diagnostic testing to uncover nutritional deficiencies, food hypersensitivities, hormonal imbalances, gut health issues, or genetic predispositions that could be contributing to chronic migraine. Treatment strategies are highly individualized, incorporating dietary changes, supplementation, detoxification, stress management techniques, and possibly acupuncture or chiropractic care. The goal is to reduce inflammation and restore optimal function to the body, thereby reducing the frequency and severity of migraine attacks.

Irritable Bowel Syndrome


Chronic digestive issues are on the rise. Rather than solely focusing on symptom management, functional medicine approaches chronic gut issues like IBS by delving into the root causes, which can vary from individual to individual. I investigate factors such as gut microbiome imbalance, intestinal permeability, pathogens, food sensitivities, inflammation, and stress. By incorporating personalized dietary adjustments, targeted nutrient supplementation, and stress management techniques, I aim to bring long-lasting relief and restore gut health before it derails other body systems.

Brain Fog and Memory

Embrace each day with a sense of focus and clarity. Brain fog and memory loss do not have to be your new “normal.” In fact, they can stem from various factors such as nutrient deficiencies, hormonal imbalances, chronic stress, inflammation, and impaired detoxification pathways. Improvements can be made by identifying and addressing these underlying issues through targeted interventions such as dietary modifications to support brain health, stress management techniques, optimizing sleep quality, addressing gut health, and targeted supplementation with nutrients essential for cognitive function and neurotransmitter balance.

My clients also come seeking holistic help for conditions like...

  • Health history and symptom review

This part of our work involves gathering comprehensive information about your medical background since birth, including past illnesses, family history, and current symptoms, to understand the context of your health concerns and the confluence of underlying factors that are driving your symptoms. This review is a critical part of the comprehensive care process we've developed in our Berkeley-based practice, now accessible to you through our virtual care services.

  • Lifestyle review

A lifestyle review looks at various aspects of your daily habits, such as diet, exercise, sleep patterns, stress levels, and support network, to identify modifiable factors that may be contributing to your health issues and to develop targeted interventions for improvement.

  • Nutrition focused physical exam

This type of physical examination specifically assesses the condition of your hair, skin, nails, teeth, and overall body composition to look for signs of nutrient deficiencies. Findings can give valuable insights into your nutritional status and, when combined with your health history, help prioritize areas for intervention. Think of it as detective work on your health, where we explore the clues your body provides about its nutritional needs.

  • Laboratory assessment

Laboratory assessments typically involve analyzing blood and/or urine to measure important markers of health, including nutrient levels, hormone balance, inflammation, and metabolic function. Labs are critical for rapid identification of the precise underlying imbalances we need to address for you to start feeling well again.

The Work

  • Lifestyle optimization

Lifestyle optimization involves identifying and implementing changes in daily habits such as nutrition, exercise, sleep, stress management, and social connections to enhance overall well-being and reduce the risk of chronic diseases, aiming for a balanced and fulfilling life.

  • Tailored nutrition

Tailored nutrition focuses on creating personalized dietary plans based on individual needs, preferences, and health goals, considering factors such as nutrient requirements, food sensitivities, and underlying health conditions to optimize nutrition and support overall health and vitality.

  • Targeted supplements

I typically employ supplements as a bridge to a more holistic food-first approach. Targeted use of dietary supplements, vitamins, minerals, or botanical extracts can address specific nutrient deficiencies, support physiological functions, or mitigate symptoms associated with health imbalances. This supplement regimen will complement other aspects of our comprehensive health plan.

  • Wellness maintenance strategies

Health maintenance strategies encompass proactive measures to remain on the path we have cultivated together and is supported by regular health screening, lifestyle program check-ins and additional recommendations to continue to optimize overall health and longevity. This maintenance phase emphasizes the importance of preventive care and wellness promotion.
