Carla is very knowledgeable and caring. She's the first nutritionist that looked at recent blood work I had done and we made some adjustments. I love that we are also looking at the ingredients and how they could effect my organs. She is the best.

I'm very grateful with Carla. A doctor told me I needed to learn to leave tired, because of my age and my diabetes, but Carla help to feel great again, with energy and much better health in general. Thank you Carla
Carla challenges me constantly and really helps me to breakdown my thoughts and why I do things. She definitely looks at you as a whole person and goes beyond just what you are eating.
Carla is amazing. So professional. She always cares and goes the extra mile.
Very professional and knowledgeable
Carla is so sweet and personable. She takes time to get to know you and works with you to meet whatever goals you have. She also is realistic and so encouraging!
Very thorough and listens. Very thoughtful and easy to talk to. Team Carla!
Carla is amazing, she took the time to go thru all my medical history including labs and the trends in blood tests over time and looked through my numerous supplements and gave her feedback and recommendations as to how to approach them in a more efficient way. I truly appreciate all the comments and the time she spent with me during the initial consultation. Looking forward to working with her.
Going into this I did not know what to expect. I found my dietitian, Carla to be very personable and genuinely invested in getting to know me, getting to know my history and in developing a starting point specific to my needs. She truly listened and presented advice and support. I am so happy with the initial plan we developed and look forward to continuing to work together.
I have worked with Carla for about 8 months now. I was borderline diabetic with an A1C of 6. As of today my A1C is a 5.6 out of pre-diabetic range. Very thankful!!
