Plant-Based Holistic Nutritionist & Lifestyle Coach

Welcome

Hi, I’m Jaclyn, a plant-based nutritionist who utilizes a root cause approach to uncover imbalances rather than just addressing symptoms. I focus on sustainable habit-building, comprehensive lab testing, and personalized nutrition and lifestyle plans to help clients achieve better health so they truly love how they look & feel.

While I promote a whole-food, plant-based framework, I meet clients wherever they are in their health journey, guiding them toward healthier, fiber-rich choices aligned with their personal goals.

I specialize in weight management, metabolic health, gut health, inflammation reduction, healthy aging & diet optimization.

My strategies include nutrient-dense whole-food nutrition, anti-inflammatory protocols, mind-body integration, and comprehensive testing like organic acids and the DUTCH test.

Let’s eat delicious food while adding years to your life & life to your years!

What People Are Saying

Testimonials

“The most important thing I think people should know in working with Jaclyn is how non-judgmental she is. She has years of experience eating this way and loads of science/nutrition information, but I found her calm, relaxed and caring attitude just as valuable.

The initial struggle I had was understanding all the options available to animal products. There is a lot of information, recipes and science/nutrition facts out there, which can be overwhelming.

I learned how to swap out animal products and replace them with plant-based options for some of our family's "go to" meals. I felt more confident shopping for and preparing plant-based meals. I also learned how to be aware of processed foods and to check sodium content on anything packaged I was buying. I lost 4 pounds in one month. My palate changed early on (within 10 days or so) to where refined sugar (processed chocolate snacks like M&Ms) no longer tasted very good.

I learned that changing the food you have been eating for the majority of your life is a process. It does take time for the body to adjust and the gut to create the right kind of bacteria. Some benefits are seen early on and others may take some time.

I would definitely recommend Jaclyn's coaching services. For anyone that feels overwhelmed with all the information and good ideas out there and doesn't know how to practically incorporate them consistently into their daily life, she can show you the way!”

I started my plant-based life change quickly, I had my doubts at first but, I decided to try it for a month. Well, my life changed!

When I started working with Jaclyn, I was still eating meat, dairy and eggs pretty often! I also did not sleep well, and "bragged" that I could take a nap at a red light because I was always tired. I do walk a lot because I have a dog that needs to get out, but I had no real energy for regular exercise.

I kept a food journal and talked to Jaclyn regularly about different things to eat. Total surprise to me, I wasn’t ever hungry. After about three weeks, I felt much more alert during the day. Jaclyn gave me lots of meal ideas, snack ideas and grocery lists. I never missed much of anything, there were so many alternatives, even cheese. The adjustment was very natural. Jaclyn was always so supportive and full of knowledge.

As I write this, it’s been five months, I feel so healthy and I’m sleeping really well. My blood tests show my cholesterol is lower and the biggest change is that I am no longer taking daily pre-diabetic injections. A life change? Yes! Worth the effort? Absolutely! I couldn’t have done it without my coach, she is amazing!

When I started working with JacIyn, I was forgetful and a couch potato. Sometimes I became depressed and would try to “eat” my way out of it, that never works. Jaclyn started slow with me. I started vegetarian, then pescatarian and finally made the jump to vegan. I was completely comfortable with her help & constant support. I loved her food swaps & recipe suggestions. She inspired me to stretch every morning and move my body every day. She changed my life for the better. I discontinued my breathing medicine, cut my diabetes medication in half and cut blood pressure medication in half, I lost 50lbs and my cholesterol is under 100.

I feel stronger and have more energy. I am no longer a couch potato. This way of living will save your life like it did mine.
