CLIENT TESTIMONIALS
Elisabeth Bennett
📍Salt Lake City, Utah
I’ve been working with Katie for a few months now. She’s SO knowledgeable, kind, and fun to work with. After my first appointment with her, she dug right in to sending over SO MUCH helpful, detailed information to get started. I began following her protocols and purchased the HTMA & DUTCH tests. Within 2 months of starting the beginning protocol, my body acne is nearly clear. Only a few small blemishes here and there. I just completed my testing and am waiting for results, to begin a more specified protocol, based on my results.
I’m so happy with my progress and working with Katie only a few months in. I also love how affordable the products she’s recommends. I’ve been to so many other specialists/docs who have made my past protocols nearly unattainable, due to costs.
I would highly recommend working with Katie!

Katie is very knowledgeable and I loved working with her. She’s been helping me this entire year. After working with her for 3 months my fungal acne completely cleared and my Eczema just about completely cleared up. The reason it didn’t completely is because of my constant picking. It’s amazing what supporting your body can really accomplish if you just give it the right tools.

Katie is an amazing practitioner to work with and have under your belt along your healing journey. In just a few short months I've noticed a huge improvement in my skin and am finally so relieved to not rely on harsh skincare to keep my acne at bay. She is always very attentive and a huge support when anything goes haywire. I love how we reach to the root cause together and the protocols she puts together are very specific FOR YOU. Very happy I found her!

Today I passed two gigantic parasites. HUGE. I feel so good. My skin is glowing like never before. My back is 100% clear. And it used to be my worst area!!!

If you’re looking for a support, a friend, someone that listen to you and try all her best to help you out then you should look for Katie!!! I have tears in my eyes when I remember how sick I was when I started my journey with her and how I feel now, my anxiety and depression are almost gone, my gut is much better and I can eat almost everything, I’m able to workout again and so much more things that got me to trust my body again and be able to heal from all my health issues. It’s been already a year together with Katie and she will remain my forever support!

I'm just about a month into working with Katie and she's extremely knowledgeable and passionate about what she does. I already have less stomach pains/heartburn/ reflux, better sleep, better digestion and am noticing skin improvements. I would definitely recommend her to anyone looking to make diet and lifestyle changes to truly transform their health for the better!

Before meeting you I was constantly bloated, scared of my celiac disease, scared of food and feeling hopeless. Some days I would eat nothing while others I would have bizarre cravings and binge eat ice cream at 12 AM. Now I feel balanced. I actually have a metabolism. My cravings have completely disappeared. My bloating has improved tremendously. Most importantly- I feel more myself than I have since being diagnosed with Celiac and so much happier! Also- For the first time in (quite possibly my entire life) I am having regular bowel movements!! 😭 I had tried increasing my water intake, eating prunes, and taking prescription laxatives… nothing worked. After following my protocol for only 2 months I have gone two weeks with no constipation.

Katie is by far the best nutritionist I have ever worked with and I can honestly say I’ve worked with many of them. We are working towards healing years and years of gut distress and I feel heard, and reassured working with her. Katie is always there to respond to any inquiries and gives me time to really hear my journey. I am beyond looking forward to experiencing as much relief as I have experienced thus far. If I could give her six stars I would. 100% recommend if you’re looking to heal.
Bryanna Collier
📍Indianapolis, Indiana
Katie is simply put: amazing! I have been working with her the past couple of months and my metabolism has seen such an improvement. She has helped pair me with proper nutrition and supplements for my body/needs. My bloating is far less/if any some days which has been an issue for about a decade now. She is super kind and willing to help whenever I reach out on the portal! It’s not a consultation and move on mentality - I know I can reach out anytime and she will brainstorm solutions with me! I strongly recommend working with her!

Katie has been a tremendous help to our family with regards to our nutritional health and overall well-being. She has been there for us every step of the way providing guidance, knowledge and assistance especially throughout difficult times in our day to day life. We are extremely grateful to Katie for everything she has done for us and look forward to working with her again in the near future.
Thank you Katie!!!

I recently did an HTMA test and met with Katie because I have been struggling with fatigue, acne, blood sugar issues, and PMS symptoms. I am a Nutritional Therapy Practitioner and I have a good understanding of foundational health and how to support my body, but it was time to get a deeper look at what is happening on the inside. After meeting with Katie I felt like I got some answers to why I am struggling with these symptoms and she explained everything so well. I learned a lot just from our meeting because she went into detail on every single mineral and how it relates to other minerals and ways to support them. She also sent me a detailed outline of our session notes and a protocol. I loved that her recommendations were food, lifestyle, and supplements. I definitely plan on working with her again in the future and recommend working with her if you are looking for 1:1 support!

📍Vaughan, Ontario
Katie is an incredibly knowledgeable nutritionist and has helped me completely change my outlook on food and what “eating healthy” actually means. I’ve taken away so many important points in regards to a proper diet, and this has significantly changed my relationship with food. If you’re looking for help with anything digestion-related and especially for a long-term solution to better skin, Katie is your go to! Highly recommend!
Jennifer Burns
📍Oak Lawn, Illinois
I started working with Katie when I purchased the 3 tests to get some much needed answers for ongoing issues I have been having. She was a breath of fresh air after begging doctors for years to help me get some answers. She was thorough, explained all my results and set me up with a protocol I am excited to jump into. I finally feel like I have some answers and a plan to find some healing. I look forward to continuing to work with Katie as well during this process. If you are on the fence about taking the steps to find answers, you won’t regret choosing Katie!

Katie McKersie of Holistico has been so helpful for me. After I went off the pill after being on birth control for 8 years, it was a scary thing to navigate. Katie and her programs have helped provide direction regarding my hormone imbalances that came from birth control. I can say with confidence that the Holistico program will greatly improve your life and get you back on track. I am able to let my body do its work without any interference from the doctors that did not take the time and care to understand my needs and body functionality goals. I have recommended Katie to every member of my family! Thank you Holistico for changing my life
Alexandria Garreau
📍Beachville, Ontario
Katie has been beyond helpful & knowledgeable. I was worried to invest in myself as I thought I could figure out my acne on my own and fix it for good without help. However, when I came across Katie’s page, I started to realize that maybe I don’t know as much as I thought I did. I took the leap to begin seeing her and I have 0 regrets. After a few months my skin has significantly cleared up and I, in general, just feel better. I’ve struggled with acne for 6 years, so to see this much improvement has been amazing and just a dream come true. If you’re also struggling, I highly recommend taking the leap and investing in your skin with Katie, you wont regret it.

The experience I had with Katie was perfect. She is so caring and generous with her time, i felt very confident working with her. We did functional testing and i loved the way she helped me actually understand my test results by explaining every marker and solution for each. I would work again with her any time!
Marjaneh Ansari

I was diagnosed with PCOS 5 years ago and was put on birth control and metformin. When coming off the pill all my symptoms returned such as acne, hair loss, weight gain, hirsutism and irregular periods. Katie helped me through my journey of coming off the pill and balancing my hormones which resulted in so much more than just the reduction of symptoms. I now feel less anxious and my mood and energy levels have increased significantly. I feel more confident in myself thanks to Katie’s help and her knowledge, it so much easier for me to stick with my decision of stopping birth control after 5 years and fixing the root cause of my PCOS while reversing symptoms. I was always told my doctors that the only thing that will help with my PCOS is birth control and I am now so happy to have found someone who actually listened to my concerns and addressed them.

Katie is incredibly knowledgeable on a variety of topics from acne solutions to gut health to hormonal cycles. I have been helped by her E book on SIBO, which most medical practitioners know nothing about, and a ton of her free information she provides online. She has so much practical knowledge and support to help figure out the root cause of health issues, not just a bandaid approach to symptoms.
Cassidy Ann
📍Toronto, Ontario
Katie is so passionate about her work and went above and beyond to help me with all of my issues. I am so grateful to have found her company. I had been struggling with heart burn and muscle pain for so long and nothing was working but Holistico was able to provide me with all the advice/resources/help I need! You cannot go wrong with this place.
Georgia Lapenat
📍Ottawa, Ontario
Katie is the most passionate practitioner out there. Not only is she incredibly supportive, but she lives and breathes what she practices. Since the beginning of my gut healing journey, she has been there for any questions I have and has guided me through the whole ROUGHEST times. Katie is incredibly knowledgeable and seeks sustainable healing for all her clients.

Katie provides such a wonderful, holistic service! Katie is super knowledgeable and supportive! Not only gives you the knowledge but fully supports your journey along the way.

Kate is a not just a great coach, she’s a good friend. She’s someone you feel comfortable relying on. I appreciate her in every way.
Julia Somerville
📍Toronto, Ontario
Katie has helped change my life as well as so many others. Her passion and genuine concern for people’s health is inspiring. I have suffered from gluten sensitivity/celiac disease for years and always assumed it would be something I lived with for the rest of my life. Katie looked at the big picture to figure out the root causes of my issues instead of fixing it with a “band aid approach”. She makes you feel heard and understood and is someone I trust with my health. If you are suffering with anything gut/hormone related and feel like your issues are being overlooked I highly suggest reaching out to Katie for help!
Stephanie Harris
📍North York, Ontario
I have been to so many nutritionists and Katie is my all time favourite!!! She is just as invested in your journey as you are and goes above and beyond what you would normally expect! I could not recommend her more!
Melissa Khalife
📍Miami, Florida
These services have changed my life for the better! I have worked with Katie for the past few months and have seen real results that make me stronger everyday. after struggling for 10 years with major hormonal issues, I finally have answers and protocols that the doctors never gave me. Katie is so patient, kind, and attentive and wants her clients to feel as great as they can so she is very dedicated to your journey. 1000% recommend to anyone who is ready to take back their health and regulate their hormones.
Amanda Brabec

I would highly recommend Katie & Holistico to anyone looking to better understand their hormones to help heal their acne! She is so knowledgable & makes the information very approachable.
Megan Fixter
📍Toronto, Ontario
Katie is very knowledgeable. I completed her 1:1 program and am looking forward to diving into her Acne Solution program on my own time to continue my journey. I was not able to complete any testing (GI Map, Dutch etc) but she was able to look at my bloodwork and give me context about how I should be healing.
