    Is Dr. Siu still practicing in the Pomona and Ontario locations? I called and they said she was no longer in practice. How can I being able to reach out to her?

    Wondering the same thing :(

    Which hospital do you deliver at?

    Pomona Valley Hospital

    The Yelp page says you're closed from yesterday and today and the number ending in 0030 is always with busy ring tone. Can you give an alternative number to reach? Thank you!

    The Doctor is extremely caring and very experienced. Also the staff is very friendly…read more I recommend the Care For Womens Medical Group They will take care of you!

    Review for care for women's…read more I have been coming to this location since 2012 now and each and every time I have went there has been discrepancies, or I was misinformed or I wasn't informed on time there's always an excuse with this place. Also let me add, it's impossible to get them on the phone, and don't ever leave a message for the supervisor because she will never ever call you back! It's impossible to get any type of answers from them let alone her. They never meet you halfway when needing something or requesting something, it's literally scratching nails on a chalk board trying to get something done for One-self at this office!! I will never EVER be returning to this office again and am so grateful i got a new doctor, new staff in a new environment with people who actually know how to follow up and do their jobs and actually care about it and US. This establishment does NOT care about YOU. This establishment ONLY cares about what it says on your insurance card and how much they're getting out of it, don't be silly. Oh did I also mention that you never actually see the doctors !? yeah you always only see a nurse practitioner. You will be very lucky and have to argue immensely to try and get seen by a ACTUAL doctor and also let me add you will probably see a doctor from the timeframe you ask for it, pushing a good five months or maybe even more! They do not care about you or your concerns! They like to delay your health as much as they can. You're literally only paying for the environment on the ambience that this place likes to carry , you're better off finding a legitimate, mature and dedicated doctor in the ghetto parts of San Bernardino. They like to push every appointment out as far as they can so that they can get as MUCH as they can from your insurance company! I've seen it happen to me MANY TIMES. I've seen it happen to my child as well while she attended that office as well as many other patients who have left due to the same issue. I will also be calling out the person that likes to handle insurance's idk her title of dept. But her names "Ver**ica" she's a very self centered crappy person. She's highly judgmental, goes based off of your super old history, which you have definitely made up for. She does not give a damn about you or your health. She does not care about anything but her paycheck!!! Which I'm sure isn't that High since she is so unhappy working there. I was told that by someone that works there I won't disclose her name that it is because of HER that I was not able to speak over the phone with my doctor for my appt. Something that I had been waiting for almost 3 weeks to discuss results and the next steps, so based off of her nasty, ridiculous, immature judgment she took it upon "herself" to charge me upfront 100+ dollars deductible fees for a "telehealth" visit which mind you, you are not supposed to do. Telehealth visits are only $15. Don't let them EVER tell you guys different! But this nasty witch Veronica had the nerve to make a "bad judgment" call and want to charge me upfront and then took the initiative "herself" when I stated I didn't wanna pay those funds upfront and to bill me, because again it's not supposed to be requested of me due to the type of visit, she decided to CANCEL the visit herself!! shame on you, Care For Womans and shame on Veronica karma will be coming back to you... trust me you guys don't waste your time here go elsewhere and hopefully you don't run into that nasty witch Ver**ica

    Been trying to call for two weeks to make appt but no one picks up or reply back! Emailed but it's…read morea bad email, are you still operating?

    1 star for front office staff I truly believe Dr Norman…read morelamberty deserves all five stars which is the basis of the five star review but if it wasn't for him I would have been out of this place immediately. Being on medi-cal and finding functional medicine doctor has been life changing. Yes he takes other insurance. He gives me his time,knowledge and I have seen tremendous results seeing him. When I first found him after my first appointment the front office went a whole year without answering my phone calls or calling me back. Told it was a phone system issue. Now i finally got through this year and been back with him, the trouble still stands of reaching the office sometimes I have to call eight times a day before they finally answer or not; they never return a voicenail and my prescriptions are never filled when leaving my appointment. I've never had an issue calling my doctor to have my prescriptions refilled anywhere else and the front staff always blames the doctor, I'm not a complainer but they make me feel like I am a bother. This medication is important to my well-being. I feel like their front staff lacks compassion it's one thing that you're not greeted when you come in it's another to be put aside like it's not a priority when it comes to our health. They started doing blood draws and I told them I dont do well and they said I just need to not be anxious and when I started sweating and feeling dizzy they just sent me on my way I had to ask to sit in lobby which was so embarrassing for people to watch me while I try to pull myself together. I just go to quest where they lay me down and have ZERO issues with the blood draw. I have my next blood test in 2 weeks (3 months apart from previous) and have been without my prescriptions for a month. I am extremely grateful for dr lamberty but wish this cycle of having meds then being fully without them would cease and my care could run smoothly without worrying about trying to reach them. Last time I had to make another appt to see him just to get the refills this time I couldn't get an appointment before my follow up date appt already set. It is just irritating but worth it because the doctor is fantastic and the other doctors I have seen had very concerning treatment suggestions.

    I came here years ago and it still haunts me, and I still remember it clearly. The appointment…read moreseemed rushed, she seemed really annoyed at all my questions. Pretty much a quick exam and I got to ask like 2-3 questions as she was one foot out the door. At the end she sent an ADDITIONAL lab test in which I didn't fully understand was being done because everything was so rushed! ON TOP of that, it wasn't covered by my insurance! You would think they'd have a bit more consideration to say "hey, here's all the tests she's ordering, make sure the costs with your insurance" but NO I didn't even know it was getting done! I called the clinic who directed me to the doctor and she sounded extremely annoyed over the phone that I was questioning why she ordered an additional test without making it clear to me. After arguing with her, she forwarded me to to another woman, Sandra Alvarez, out of obvious frustration. After speaking with Sandra from "patient services", she gave me the complete goose chase for 2 months (obviously on purpose) until my bill was too overdue and at the end I had to pay the lab everything I owed, 150$ out of my pocket.

    I use to go to St. Jude for all my needs and recently changed insurances. When visiting my health…read moreinsurance app, Dr. Ota was rated one of the highest of OBGYNs on the list. After becoming pregnant I thought I'd give her a try and am soooo happy I did! She is not only the nicest doctor I've seen but takes her time with discussing any questions my husband and I have. She is always in a positive and upbeat mood and I have total trust in her. I feel reassured that she will help me make the right choices for me and my baby. The office staff is always courteous, I hardly wait more than 10 mins to see my dr. and the place is always clean and organized. I would very highly recommend Dr. Ota if you're pregnant and looking for someone knowledgeable in the field and reassuring. She's helped make my pregnancy journey and easy and enjoyable one!
