4/28/23 1:00pm - Been waiting on a referral for a month now. My insurance told me that the referral paperwork was rejected because Calleros submitted it incorrectly. I called Calleros this morning to follow up since it's been a month now. They told me someone would call me back by Friday 3pm. It's currently Friday 1pm and their voicemail says they are closed for the day. The WORST MEDICAL SERVICE I HAVE EVER RECEIVED. The staff acts like they're doing you a favor by speaking to you and lying to you. CLOWNS.

4/28/23 2:30pm - These clowns called me one hour after I posted this review on google. I told them they need to call my insurance company. They yelled at me and used vulgar language. And hung up on me. CLOWNS.

4/28/23 2:52pm - These clowns called me again and claimed they have no idea who from their office called me and hung up on me. CLOWNS.

4/28/23 3:30pm - My insurance called me to tell me that Calleros' office finally submitted the paperwork for my referral. And that they submitted the paperwork for the WRONG DOCTOR. CLOWNS.

I've been a patient of Dr Gustavo Calleros for over 15 years! He is a wonderful doctor in every way. My whole family sees him. He's seen us for regular exams and and not so regular exams. He's helped us through Chrons desease with my son, MS with other son, out of control diabetes with my husband and depression with me. He's there for you through thick and thin. He is a doctor that takes time with you and never makes you feel rushed. He is very knowledgeable and caring. If you are looking for a doctor He's the one for you!! I recently moved to Reno, NV and I still fly down to see him. Yes, that's how great he is. And behind every good doctor is a good medical staff. The girls are very helpful and kind. It's always nice going somewhere where you recognize everyone. The girls have been with him a long time. They're all wonderful!!
It's a Win,Win office!! Thanks for all you do for me and my family.

If I could give a zero star I would. I was given the wrong authorization for a completely different body part. On top of that, the doctor I was referred to didn’t even take my insurance ! I have a really bad hip injury and have been waiting on this auth. For over a month. Everyone who answers the phone is rude and has a bad attitude. I have no idea how these people get the jobs they do. One lady told me I had to call the doctors office where I got an MRI to get the MRI CD. I don’t get paid for all that, you do, but they are lazy and don’t want to do their job. They have no care for anyone. Only for a paycheck. They couldn’t care less about anyone’s actual feelings, pain, sickness, nothing. If you want to get screwed over and jump through hoops , but all means, get this doctor. Good luck folks!

He's the best primary care doctor EVER!!! He's incredibly compassionate and he gets to know and relate to his patients to make them feel cared for and understood. I recommend him highly.
