"This is the worst doctor and doctor office ever! Do not go see them because you’ll never be able to get an appointment, you’ll never be able to get through on the phone, and if you do, you’ll wait 45 minutes on hold, the staff is constantly changing, and you’ll never get any help that you need. I’m being generous, giving them one star! They don’t even deserve that. And you’ll never get to see the doctor, I’ll just finish with that."

"Always a long wait time.. typically 20-30 minutes. "new" phone system puts you on hold for about 20 MINUTES then goes to an answering service, that is working from home. NEVER gets a call back. NEVER gets to talk to a person. Had to actually go to the office to talk to someone, and just god lip service about their phone. FIND ANOTHER DOCTOR!!!!!"

"Pomona office short staffed difficult to get through. It took me 3 month to get an appointemnt even I needed the appointment badly. From first appoinmtent the doctor recommended radioactive iodine therapy. When checked with another doctor for second opinion he put me on medication for 2 months, my thyrod went back to normal I don't recommend this doctor nor the Pomona office."

"Have been trying for several days to contact them to make an appointment and the do not answer the phone. Have just been left on hold. I’ve been a patient for over 15 years, what’s going on? Did she close her office, is she gone away. If she’s left, she took her manners with her."

"The amount of time you are asked to wait to see Dr. Konca is absurd. Even trying to reschedule an appointment, I've been on hold for over 30 min two different times and still haven't been able to talk to anyone to reschedule an appointment. She may be a good doctor but the lack of respect for other people's time is not tolerable. I'm looking for another doctor now. "

"My father was experienced high blood glucose for 3 days (450s) and she never called us back to advise us what to do. Went to the ER. Still waiting a call back."

"AWESOME!!! Finally a doctor that actually care about her patients. Pomona office is awesome everyone is so nice. I recommend this Endocrinologist. "

"Horrible! Avoid this office if at all possible! You will have to be ready to demand and push for a prescription renewal- and then it will maybe, possibly be the correct dose or medication. They won’t answer their phones or ever return a call after leaving a message. Awful, horrible patient/physician interaction. Avoid!!!"

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
