I've been going to Dr. Mendoza for 4yrs and I have recently have gone somewhere else because of his staff. Dr Mendoza is great no problems. When I took my second son there I had problems with my insurance. So I told the front office people how to bill my husbands insurance not mines. So they neglected to tell 4 months later that one of my bills wasn't paid and I couldn't talk the nurse about my baby's rash until I made a payment. So I stupidly gave them $100. I had a huge argument with front lady and billing lady. Because they blamed me for something they did wrong which is bill my other insurance. So I went else where. Now they took the bill to collections and demanded $1,000 when bill was only $500. Now I'm stuck doing their job which make them bill my other insurance which they should've done in the beginning. And figuring out this collections. I am so very mad. So FYI be careful of how they do their billing so this doesn't happen to you!
