I would like to share my experience with Lorraine during my weight loss journey. For years I have battled diets, struggled with weight loss, high blood pressure, limited mobility, and other undesirable health issues. Soon after I retired, my journey to achieve a healthy lifestyle began with Lorraine. She is a great support and offers wonderful advice for those who have unhealthy relationships with food. She is able to make me see things for what they really are. Now I am 65+ pounds down and have been able to reduce my high blood pressure medication and have noticed my stamina and energy have increased. My understanding about how my mind sees food and how to know when I am truly hungry can be attributed to Lorraine's guidance and advice. I would recommend Lorraine to anyone who struggles with weight loss. I send many thanks to Lorraine for all her lessons.

In late 2023, I was diagnosed with high cholesterol, pre-Diabetes, and stress by my primary care physician. I sought out and found a wonderful local nutritionist in the form of Lorraine Matthews-Antosiewicz who has taken the time to understand my background, lifestyle habits and intake of food. She has been instrumental in helping me lower my bad cholesterol level by 31 points as I am trying to avoid takin a statin to lower it. Lorraine said that these other areas in life also influence my situation: SLEEP is the number one determination of health (wake up during the night; sleep apnea) – sleep deprivation will interfere with weight loss. STRESS – blood sugar INCREASES. EXERCISE (swimming and weightlifting) Lorraine and I communicate via teleconferencing over the Web which works extremely well and makes things very convenient. We initially spoke once a week, then once every two weeks, etc. We now speak once every three months. In the past two years, Lorraine has proven to be extraordinarily understanding, compassionate, and extremely knowledgeable in her area of expertise (nutrition) and is able to get me back on track when I slip up. I would strongly recommend her to anyone looking to change their life and relationship with sleep, stress, and exercise.

A few years ago my wife contacted Lorraine to provide nutritional guidance for one of our children. Since that time we have met with Lorraine regularly and I cannot say enough positive things about her. She is knowledgeable, thoughtful, and excellent at explaining things in a clear and practical manner. The nutritional information she has given us has been personalized, realistic, and genuinely helpful. We have seen positive results and really appreciate her professionalism and care. We highly recommend her services.

Not very helpful for me and her personality and style of session were not the best fit for me. I tried a handful of sessions just to see if there would be any change but there was not. If it's your first time seeing a nutritionist, like I was, I don't recommend. Prior to initial session you are expected to fill out a lot of paperwork (which is fine) but based off our initial session she didn’t review any of it. During follow up sessions she does not follow up from the previous session, she expects you to lead every session. Overall just not a good fit.

I am very thankful to have found Lorraine to be part of my health journey. Not only did she help me to lose weight in a healthy way, but also to keep it off. I learned to be a mindful eater and to listen to my body. Now, I have a more balanced diet, feel stronger, and have more energy. I will forever be grateful for her guidance because now I'm a good role model for my kids to have a healthy and active live style. I don't worry about the number on the scale, what's important is how good I feel in my own body. Thank you so much all of your help.

I thought I was at a midlife impasse until working with Lorraine, who realigned everything I thought I knew about eating right. In only three sessions, she helped me optimize my nutrition and set me up with a go-forward plan I can confidently implement on my own. No hideous diet and weight-loss talk here, only realistic ways to strengthen yourself and think differently. Highly recommend!

I’ve been working with Lorraine for several months now and she has helped me integrate more fruits, vegetables and protein to my diet. Lorraine helped me to understand about eating healthier and has listens attentively to my story without judgement. I haven’t been this motivated about living a healthy lifestyle until working with Lorraine, Thank you!

Had to show the wonderful experience I’ve had with Lorraine. I started working with Lorraine over a year ago. I’d been searching for a nutritionist who could help in improving my overall relationship with food. I was not looking for meal plans. Through the work we’ve done, I feel like I’ve completely transformed my approach to food overall. I have a solid handle on how to enjoy sweets and treats without overindulging, prioritize nutrient dense foods, be mindful of vegetables and proteins. Lorraine was also great with overall health check-ins - helping me work on creating physical activity goals, helping me navigate diet related changes due to overall health, etc. So grateful for her help and support and highly recommend reaching out to her even if just for an intro session.
