What working together looks like...
A typical starting sequence, tailored to you.
Your first steps
1. Your initial assessment — 60 minutes
We review your intake form, take a detailed history, and discuss your concerns and goals. I'll review recent blood work (if available), and recommend additional testing where helpful. You’ll receive initial nutrition, lifestyle, and foundational supplement recommendations, followed by a written treatment plan summary.
2. Review your results & build your strategy — 30 minutes
Usually about two weeks later, once test results are available, we review the findings and refine your plan. You’ll receive an updated written treatment plan summary after this appointment.
3. Support to put your plan into practice — 15 minutes
About 3–4 weeks later we check in on how things are going. This is a chance to ask questions, work through challenges, and identify manageable next steps to keep you moving forward.
4. Review progress & adjust — up to 30 minutes
Another 3–4 weeks later, we assess your progress and adjust your care based on how you're responding. When helpful, we will review repeat blood work, but this visit does not depend on needing more testing. You’ll receive an updated treatment plan summary following this visit.
Beyond these first appointments, we continue building on your progress—addressing the areas that matter most for your health now and in the years ahead, with practical support to help you put your plan into action.
Meet Dr. Jennifer Haessler, ND
Hi, I’m Dr. Jennifer Haessler, a licensed Naturopathic Doctor and certified fitness and nutrition coach with over 20 years of clinical experience.
My focus is helping women navigate midlife, including perimenopause, menopause, and metabolic health.
My own experience of perimenopause has also shaped my interest in this stage of life.
I bring together clinical experience and practical nutrition and lifestyle guidance to help you understand your options and make informed decisions about your health.
Good midlife healthcare is about more than prescribing hormones.
Hormone therapy can be incredibly helpful for women in perimenopause and menopause, and it’s one of the treatment options I prescribe when appropriate. But the whole picture involves more than hormones.
Fatigue, disrupted sleep, weight and body composition changes, mood changes, and other symptoms can have multiple contributors. I look at your symptoms alongside your health history, nutrition, lifestyle, and relevant blood work to understand what may be contributing, where it it's most effective to focus, and in what order.
Before you book...
Both. Virtual naturopathic appointments are available across Ontario, and in-person appointments are available in Southampton at The Holding Space, 143 High Street.
You can choose your preferred appointment type when booking online.
Yes. I'm currently welcoming new patients from across Ontario. You can book your 60-minute Initial Naturopathic Health Assessment and Strategy Session directly through my online booking page.
You can view current fees for each appointment type, along with availability, by clicking any “Book Your Initial Assessment” button on this page.
You don’t need to arrange new testing before we meet. If you have results from the past six months, we can review them at your initial assessment.
I’ll recommend any additional testing that may be helpful at the initial appointment, based on your health history, symptoms and goals.
Yes. As a registered Naturopathic Doctor in Ontario, I can order blood work.
Blood work ordered through a Naturopathic Doctor is not covered by OHIP. Any recommended testing and associated costs will be clearly outlined in your treatment plan for your approval before testing is ordered.
I can prescribe topical bioidentical estrogen and progesterone, when appropriate. If another form of hormone therapy would be better suited to your needs, I can make recommendations and refer you to an appropriate healthcare provider for prescribing.
Many extended health benefit plans include coverage for naturopathic care. Coverage varies by plan, so check with your insurance provider for details. You’ll receive a receipt after each appointment that you can submit for reimbursement.
No. If you’re ready to get started, you can book your initial assessment directly. If you have questions about whether working together is the right fit, you’re welcome to book a complimentary discovery call first.
