This review is only based on first impression appointment call!…read more I just switched my daughter over to Dr. Sun after being with another doctor for 12 years. My insurance isn't effective until July so we haven't met any of the staff personally. It's super important for me to get great service on the first call. That first impression means a lot and it went very well. The gal was really nice and helpful. I'm hoping that we will have the same experience in person. I'll update my review next month.

I had a very upsetting experience with Dr. Khawam. I have been dealing with severe back pain for…read morealmost a year, and the pain has significantly affected my sleep, daily activities, and ability to work. I attempted to have an MRI done three separate times, but because of my severe claustrophobia, I was unable to complete it. I came to see the doctor because I wanted to know if there were other options, such as sedation, that could allow me to get the MRI or if there were other tests that could help determine what was causing my pain. Instead of listening to my concerns, I felt that I was being dismissed. He questioned why I needed the MRI and what I thought it was going to show. He told me that my options were physical therapy and losing weight and suggested that my weight was likely the reason for my back pain. I understand that my weight is something I need to address, but I know my body, and I know that the severe pain I have been experiencing is not something I should simply be told to live with because of my weight. I was looking for a doctor to listen to me and help determine why I have been in so much pain. When I became upset, he told me to give him a moment while he spoke with a colleague. When he returned, I felt that his attitude toward me was even worse. He asked me what I thought was wrong with me. At that point, I became overwhelmed and walked out because I no longer felt comfortable continuing the conversation. I want to give a special thank-you to the front desk staff. They listened to me when I came out of the room upset, allowed me to explain what had happened, and helped me get connected with Corrina, the nurse. I truly appreciate them taking my concerns seriously instead of ignoring what had happened. I am also very grateful to Corrina, who called me, listened to me, apologized for my experience, and told me she would speak with the doctor and his supervisor. Most importantly, she actually helped me move forward. She was able to get a CT scan ordered as an alternative since I could not complete the MRI, as well as referrals to neurology and neurosurgery to explore other options, including ways I may eventually be able to complete an MRI. My CT results showed that there are issues with my spine that require further evaluation, which was extremely upsetting to me because I felt that I had initially been ready to be dismissed as simply being overweight. I am sharing this review because patients deserve to be listened to, treated with compassion, and taken seriously, especially when they are experiencing severe pain. I am thankful that I spoke up for myself and that the front desk staff and Corrina took the time to listen and advocate for me. Without their help, I don't know if I would have gotten the additional testing and referrals I needed. Thank you to the front desk staff and especially Corrina for treating me with kindness and helping me when I felt like I wasn't being heard.

Awful experience. Pomona location…read more Doctor was a new resident so she was trying to demean me to prove she knew what she was doing. She wasn't the doctor I had chosen so unfortunately I was stuck with her. She dismissed a picture of me almost in anaphylactic shock as "I suggest taking a Claritin." She dismissed how I described living in mold infested housing meant I had symptoms of fatigue, she misunderstood mycotoxins and said "no, if you had a fungal infection I wouldn't been able to tell. I work with those people in a hospital." The unbelievable student assistant/student doctor also laughed at me after asking me what I thought I was diagnosed as. The other doctor didn't even care that the girl asked me that, she was already out of the door and didn't care. I guarantee you she brought the student doctor as an example of "here's a patient who's symptoms aren't real, let's look at her as an example of what happens to people who make up symptoms." Because of this now I'm gonna have to pay out of pocket for actual specialists and not inexperienced residents who dismiss everything. More expensive out of pocket but it will be worth it to avoid this type of BS.

First off, I'm not one to leave a review because I believe the service you get speaks for itself…read more Being a health care professional myself for over 40+years working in the field from level of care to supervisory gives me a great amount of experience to provide a through review. First the office staff are very professional and accommodating, next the clinic staff who takes your vitals are professional and ensure they use universal precautions to ensure there are no cross contamination from patient to patient. This is a biggie for me when it comes to doctor offices. Last, Dr. Rishi Majithia. This is my fourth appointment seeing him. I was recommended to him by my daughter in law who is a medical professional. I was initially very skeptical because doctors now days care more about money than the care they provide. Dr. Majithia, my first appointment he listened to my complaints and concerns, gave his feed back, made slight recommendations and genuinely seem as if he cared. By my second appointment he actually was able to repeat some of the concerns from the previous appt and made excellent recommendation. This let me know he actually was listening and taking appropriate notes the first appointment. By my third appointment he addressed all my medical concerns, started me on new meds which we both agreed, made legitimate realistic goals for me to follow and seemed as if he really cared about my well being. Again he was able to recite all my previous complaints from the past appointments. ((He really Listens). Today, I had my fourth appt. I can now say I have found a provider who is knowledgeable, competent, up to date with society and current medical trends. Knowledgeable of Diabetes, and is genuinely concerned about his patients. Seems he has a passion for his profession. When he took his Oath to be a doctor to care for patients he did it because he wanted to see a change in people and he care about people's health. If your looking for a doctor who cares about his patient's, current on medical knowledge, doesn't rush you during appointments, listens, there is no need to go further. Dr. Rishi Majithia is an excellent choice!

Update: I haven't yet received an apology from the offending…read moreparty mentioned below. However, I am extremely impressed with the quick and efficient attempt to remedy the situation. Ryan from Upland Medical Group, not only apologized, but was able to get me a referral without even having to visit the PC office that Gina is employed at (#Win). Additionally Ryan was knowledgeable about the OBGYN that he referred me to, was on stand by to ensure I actually was able to make an appointment that was sooner than a week, and offered guidance on choosing a different primary care provider, AND a pediatrician for the baby on the way. Ryan was honest, patient, solution oriented and went above and beyond. It's because of him and his level of service that this review is being updated. Thanks to Ryan, I look forward to a long and thriving relationship with Upland Medical Group/Pomona Valley Medical Group. Previous Review: Dr. Mantha's staff member "Gina" that handles booking appointments for upland medical group was beyond rude and made an already stressful situation even more stressful. She started being nicer once I asked for her name, but she was anything but understanding or helpful. I'm almost 7 months pregnant, have not seen a physician... it took forever for United health care to reassign my primary care physician and receive the card. I'm desperately trying to get prenatal care and HAVE to have a referral to do that. I sincerely hope that Gina isn't an accurate representation of the level of service Dr. Mantha provides. If she is, I'm glad it's only a referral... May update this review after I actually meet with Mantha on the 19th of feb

BUT...his wife who also works in the office has ALWAYS made it difficult. She is rude and lacks customer service. I recently convinced my parents to move to a new pcp about 2 months ago because he was no longer giving my mother answers to the excruciating lower back pain she was feeling along with the dizziness she was experiencing in her everyday life and pain in her incision from her mastectomy she had nearly 19 years ago. Dr gomez answer to everything was "everything looks good" so he would never send her out to a specialist because he said "he did it all" Fast forward to today we just found out from her new internist doctor that she has Lupus and has had Lupus because her prior doctor Sergio Gomez had it in her files but NEVER bothered to tell us. Her legs shake when shes just sitting, she walks around daily feeling dizzy she had an ear sore that never went away until I had to do my own searching for an ointment that finally fixed it. This man has really let his practice fall through the cracks and they dont like patients that question anything or they will refuse service, after all it is their own practice. Good luck with this doctor.
