I worked with Alexandra and she was extremely helpful and insightful hence the five stars. She is personable and gives plenty of tips on sustaining a healthy lifestyle. I had some issues with insurance after and some general pricing discrepancies that went along with it. After working with Ms. Lanzano and Kathy in billing they were very pleasant and easy to work with. I'm glad we were able to sort this all out and move forward. For anyone seeking the assistance of a nutritionist I would highly recommend EN, but make sure to clear it with insurance first to avoid the situation I was in.

Emma is a supportive, mindful, and communicative clinician. As an eating disorder therapist I am cautious with the referrals that I give out to my clients and I feel confident referring them to Emma!
I highly recommend Emma to those looking for support with disordered eating. She is knowledgable, caring, empathetic and it is evident through her work that she deeply cares about the quality of care she provides to her clients.

Follow up: My first appointment didn't go the best, there may have been a miscommunication in understanding what I was looking for. They allowed me to come in again at no charge and I met with Lisa who was amazing! She gave me lots of useful information in a clear and understandable manner that will make it very easy manage my nutritional needs. I also had an RMR done to get an idea of what calorie range I should be in based on my exercise levels. I will definitely going back to them.

The team at Essential Nutrition were very helpful during the initial stages to get my wife, me and our insurance set up so we could start our journey to healthier eating habits. The only thing that was a little wonky was using the patient portal to provide the information before our first visit. It could have easily been me, but I felt like I didn't get enough direction and/or instruction on how to use the format an what was expected before I showed up at the first session.
Alex has been extremely helpful in directing me and my wife into better eating habits and has held us accountable for the

Lisa helped me learn how to eat after I was diagnosed as gluten, grain and dairy intolerant. There weren't a lot of resources then (or foods to substitute with) but Lisa made it easy for me. She provided recipes, alternative foods and helped me with my mindset about "losing" so many foods from my diet. If it weren't for Lisa I wouldn't have known what to eat beyond a handful of foods. And now I'm healthier than ever and know exactly what to eat!

Kathy taken the time to get to know me, and what would and would not work for me. She gave me two paths forward and the one we chose together I feel is truly working and I can sustain it. Kathy is also very knowledgable and easy to work with.
Essential is easy to work with, has an easy to use portal and most important matched the right nutritionist who is an expert for my situation.

I have been working on and off with Lisa for the last 7 years. I first came to her when I needed help to stop dieting and just learn how to trust my body near food. What I love about her is that she knows the emotional component to food but she also understand the scientific and nutritional side as well. She helped me learn how to be able to eat all foods with peace of mind and peace in my body. Then, again through pregnancy she helped me trust my body more with all the cravings I had. Now I see her whenever I feel I need some extra support around my relationship with food! Most of all she helped

I give the expert team at Essential Nutrition the credit for helping me to build the necessary skills, knowledge and awareness in order to heal and start to fuel my body properly. Lisa is an incredible clinician— she is compassionate, caring and extremely knowledgeable. She knows exactly how to deal with someone who is struggling to find healthy living; she is both supportive and understanding but also tough when you need to hear some hard truths. I also worked with Ashley, who helped me to overcome a lot of my fears associated with certain types of food and nutrition.

Ashley is so helpful in my navigation of learning to enjoy the food I eat, eating until I'm comfortably full and not using food as any thing more than fuel. My relationship with food has changed entirely! She is personable, supportive and very funny. It's nice to enjoy my appointments as well as getting expert help on nutrition. Thanks, Deanna
