My family and I have seen Dr. Zuniga, Espinosa for years, they are helpful, professional and extremely accommodating - great team of doctors that take the time to listen to all our concerns.

Faye H.

Dr. Espinosa always makes me feel important and cared for. So glad I found her 3 years ago.

Monica L.

Dr Zuniga has been my mother in laws, father in laws and now my father's doctor for the past 5yrs or more. He is very personable and knowledgeable and patient. There were days when I brought both my In-laws in for a back to back appointment with him and he took his time in addressing each of their needs. He truly enjoys his profession.

Gerald G.

Dr Zuniga is in the 1% club, a very hard accomplishment to achieve. He figured out what was wrong with me when all others failed .

Jodi V.

Dr. Zuniga. He really takes his time with you and listens. He had to fight for a test to be done by calling the insurance company himself and explaining why I needed it done. He is very smart and easy to talk to.

Timothy B.

Seeing Dr. Zuniga is almost like seeing an old friend...and how many times have you EVER said that about a healthcare professional. He gets it! We are not just an insurance # and code.

Lauren K.
