You’re feeling more tired than you used to, with low energy, bloating, stomach discomfort that’s hard to figure out. You may be eating “healthy,” but still don't feel much better with changes in weight, energy crashes during the day or not bouncing back like you used to. You might also be a parent of a child or teen in competitive sports. Between practices, games, tournament, and busy schedules, you’re wondering if they’re fueling properly to keep up with training, games, performance and growth. I also support active women in midlife who are noticing changes in their energy, digestion, weight and want to feel strong and energized.

I support PCOS, endometriosis, IBS, chronic conditions, and sports nutrition.
You might be someone who feels overwhelmed by nutrition information that wasn’t designed with your culture, body or lived experience in mind. Maybe you’re navigating PCOS, endometriosis, fertility concerns, or hormonal changes. Or you may be active and training regularly, wanting nutrition support that helps you feel strong and energized—without having to give up the foods that bring you joy and belonging. Many of the people I work with have felt unseen, dismissed, or boxed into one-size-fits-all advice that simply doesn’t work in real life.

Do you struggle to feed yourself faithfully, with care and self-compassion? Despite everything you may have heard, there is only one universal rule in nutrition: eating is a non-negotiable survival need. This is why, for some of us, eating can feel like an existential crisis. But eating doesn't have to be as complicated or scary as our culture and media present it, because eating is also one of life's great pleasures. Fed is best, and much of the time, your body exactly knows what it is doing...if only we can get out of its way. We are all born intuitive eaters, but internalized negative messages bury our innate wisdom.

I work virtually with motivated individuals or couples (in Ontario) who are actively trying to conceive or planning for pregnancy. They seek evidence-based information and personalized guidance to optimize their fertility and prenatal nutrition. With concerns about their current diet, lifestyle choices, or specific medical conditions, they are driven to provide the best start for their future child. They value the role of nutrition in this process and are open to making positive changes. Ultimately, their goal is to create a healthy, nurturing environment for their little one to thrive.

I believe that nutrition is more than just "hitting macros". Through my clinical experience, I've seen how closely food, physical and mental health are intertwined. You need someone who will consider both your nutrition and mental health, or else diet changes won't stick! Supporting close friends and family with PCOS and ADHD has deepened my understanding of how challenging it can be to live with these conditions while juggling everyday life.

Irritable Bowel Syndrome (IBS) Nutritionists and Dietitians
What is Irritable Bowel Syndrome (IBS)?
Irritable bowel syndrome (IBS) is a general term that refers to a collection of symptoms associated with poor gut mobility and function, including abdominal pain, bloating, gas, and diarrhea. IBS is very common, with some estimates suggesting that as many as 10-15% of adults within the United States have IBS. Although the two conditions sound similar and share many symptoms, such as abdominal pain and diarrhea, IBS differs from irritable bowel diseases (IBDs), such as ulcerative colitis and Crohn's disease. In contrast to IBS which is caused by issues in the functioning of the colon, IBDs are inflammatory conditions caused by overactive immune cells within the intestine. IBDs are much less common than IBS and typically more medically severe, occasionally requiring intensive medical treatment and/or surgery. IBS, in contrast, can usually be managed effectively with lifestyle changes and less intense medical intervention.

What are the subcategories of IBS?
Medical professionals generally identify four main types of IBS: IBS-C (constipation-predominant subtype), IBS-D (diarrhea-predominant subtype), IBS-M (mixed bowel subtype), and IBS-U (undefined subtype). Identifying the predominant type of IBS an individual has can be important for determining the type of treatment that is best for them, such as the lifestyle and dietary changes that may be most appropriate, as well as any medications that may be necessary. However, individuals may also experience multiple subtypes over time, as well as experience cycles of flare-ups and symptom relief.

What causes IBS?
The causes of IBS are not well understood, but symptoms are generally attributed to issues with gut muscle contraction and changes in the gut microbiome, both of which can lead to the characteristic symptoms of IBS. These issues can be caused by a variety of lifestyle factors, such as diet and stress. While lifestyle modifications may not completely cure IBS symptoms, identifying symptom-triggering foods, consuming a balanced diet, and reducing stress have all been shown to greatly reduce symptoms. IBS can also be caused by bacterial or parasitic infections within the intestine, in which case the syndrome is referred to as "post-infectious IBS." In contrast to non-infectious IBS, post-infectious IBS is less chronic in nature and symptoms will often resolve once the infection has subsided.

What foods should I avoid if I have IBS?
Specific foods that may trigger symptoms of IBS can vary person-to-person. However, common foods that may exacerbate symptoms include high-fat foods (such as fatty meats), wheat, dairy products, highly acidic foods (such as citrus), beans, cabbage, milk, and carbonated drinks. Over time, individuals with IBS are often able to identify which foods cause their symptoms to worsen and learn to avoid such foods to manage their symptoms.
