Dr. Nieto’s approach to wellness is to listen to your story.  She believes that your story is unique and it is the tapestry of your life.  Dr. Nieto believes that your health and wellness are not stagnant in time, but are a result of different life events and choices that comprise who you are as a whole human being. She understands that health and wellness are not a straight line and that many times there may have been setbacks and resets along the way. That is ok, and together she will start where you are now and continue to work with you towards healthy goals. 

Dr. Roberta is a native of Orange County.   Her own journey into medicine was unique.   Prior to medical school she worked as a microbiologist at UCI Medical Center where she interacted with infectious disease doctors who were treating patients afflicted with HIV/A.I.D.S.   Those cases touched her heart and she began volunteering as an emotional support “buddy” at the then A.I.D.S services center of Orange County.  Her microbiology knowledge and the volunteer experience sparked in her a dream to further serve others, and ultimately that led to medical school.

After graduating from the prestigious Medical College of Wisconsin, she attended and completed the UCLA affiliated Family Medicine Residency at Pomona Valley Hospital Medical Center and continued on as an attending physician teaching doctors in training.  Dr. Roberta enjoys education and teaching.  She continues to be involved in residency education, clinical precepting, and mentoring other physicians.   She has had over 19 years of experience as a medical doctor.  Dr. Nieto has also completed all the advanced practice modules offered by the Institute for Functional Medicine for root cause medicine.

In her spare time, Dr. Roberta enjoys spending time with her family, volunteering at her church, attending to her rescued pets, playing the guitar, the outdoors, organic vegetable gardening, reading, and continuous lifelong learning.
