Never had so much information given to me. The exam part was easier and less time consuming than expected. The Exam was also pleasant she was very professional and explained everything as it was happening. My visit for the outcome with Dr Barreto was also professional and really informative. I felt that I knew my overall health, risks and what to do.

Getting old is not for old people. But Dr Barreto makes it a lot easier to take. Feeling and being healtier is more important now than any other time in my life and I feel I am in great hands with her keeping me going.

When I explained to Dr. Barreto that I was exhausted all the time and couldn’t seem to find a solution to my fatigue, she took a special interest in me and ordered a comprehensive hormone panel. She really listened to my concerns and now we have my hormones on track and I feel amazing! – Stephanie P.

I was starting to feel and look older than my true age and I didn’t like it. Dr. Barreto gave me a new sense of self with fresh new energy. I feel 10 years younger and I am excited about the future. – Betty B.

Enjoyed the visit with Dr. Barreto. She explained everything completely. Good to know how everything in the body works.

I had unexplained weight gain over the past year that was becoming depressing. No one would take the time to find out why it was happening. Dr. Barreto really looked into my concerns and lab results to find out what was going on. Now I am on a plan that includes supplements and exercise and I can see the results I have been looking for. – Debbie D.

This is my second “Wellness Exam” through MDVIP. Dr. Barreto and her staff provide a thorough process in a very professional and courteous manner. I appreciate the comprehensiveness and how the results are reviewed. Dr. Barreto provides a means of improving any less than good issues and she and her staff follow-up to see that they are effective. I am very pleased with the process. Thank You,
Cindy E.

Who knew that my hormones being out of balance were affecting my sleep! Dr. Barreto fixed my problem and now I am sleeping like I did when I was a teenager. – Jim R.

The tests are great and easy to do. Gives very detailed info. Highly recommend.

Good deal works great!

Dr. Barreto explained my lab results to me very thoroughly and when I told her I didn’t want to be dependent on medications for the rest of my life she came up with a plan of supplements to address my pre-diabetes. I am so happy she considered alternatives to meet my needs and the needs of my body. – Sue H.
