Joan Yvette Sy, DO

I love Dr. Sy and her staff. She does a complete and very detailed blood panel (covered by most insurances) that no other physician has done. Within a year, I got my thyroid and cholesterol under control because of Dr. Sy. She recommends supplements from Metagenics as well as her own supplements which are a little costly but being healthy is worth every penny. I’ve never felt better! Her staff are friendly and she’s very timely with appointments. I’ve never had to wait longer than 5 minutes at this office which I can’t say for any other doctor. I’ve recommended her to several family members and friends. Thank you, Dr. Sy!

I went to Dr. Say for the first time for my yearly routine physical. I have insurance that is preventative only. It pays for my yearly exam and all of the accompanying diagnostic testing (Mammogram and blood work). Dr. Sy convinced me to use the special lab she is affiliated with for an extra $ 50 instead of Quest Diagnostics, which my insurance covered in full. When the results were in she wanted to schedule me for another visit to discuss the results, which for the most part, were fairly normal. She neglected to tell me that I would be charged out of pocket for an additional visit. When I called I was told she refused to speak with me over the phone regarding the results, as most physicians do. I would have to come in for a 20 minute visit. I called my insurance, Anthem Blue Cross, and they said they would cover the visit since it was a follow up to my well visit physical and that Dr. Sy would just have to code it as preventative. When the office called me back I was told she would not do it. She would only code it as diagnostic even though I was not ill, did not need to see a doctor, and was merely going in to discuss results and recommendations from my routine physical. Needless to say, I did not make that appointment and I’m left sitting here with results I cannot decipher on my own. To say I am extremely disappointed is an understatement. It’s no different than a bait and switch tactic. Why would anyone go in for a physical with a doctor who will only give you the results if you pay additionally for them. What a racket! Patients beware!

I have Health Net through Covered CA and saw Dr. Sy for the first time yesterday. I called a couple of months ago to schedule a well woman’s exam (yes you should plan to book in advance — I believe Dr. Sy works at two facilities but don’t quote me). The woman who booked my appointment was not bubbly but quite pleasant and informative. When I walked in, the front office was clean and I was greeted by the receptionist. Dr. Sy herself was wonderful. She is the only doctor I’ve seen who actually read every line of my patient questionnaire and addressed all of my comments/​questions/​concerns. I have many requirements going into veterinary school in January so, both Dr. Sy and her staff are working above and beyond to help me fulfill these requirements and paperwork. They made me feel like I mattered.

Oh my, this was NOT a good experience. I called Dr. Sy’s office in February to schedule a new patient appointment for my husband and was given an appointment for March 31 at 4:30 pm (my request was the latest appointment of the day). On March 26, I received a voice mail from the office that Dr. Sy has an «emergency» and won’t be able to see him on March 31. I called the next day to reschedule. I explained that my husband needs either an early morning or latest appointment of the day. Lucia gave me two options, and I told her I would check with my husband and get back to her. I called her back first thing in the morning to accept the appointment on April 13 at 4:50 (two weeks later than the original appointment). Lucia told me, I’m sorry that time isn’t available. I asked her why she would give away the appointment time she offered to me and she was pretty rude, complaining that she had to reschedule many patients (not my problem).
Needless to say, I ended up having to schedule a different appointment with a different doctor because now Dr. Sy didn’t have any availability until May and my husband’s medications would have run out by then. This is not what I would call good patient care or good customer service.
Husband: This is a complete failure of the office, They had absolutely no care for the customer time and all they care is their personal & office schedule. I would recommend anyone to look for other health care offices. The Dr. vision is absolutely bogus.

The front office lady Lucia, is very rude and unprofessional. And does injustice to a good doctor. Nevertheless its not worth the wait time and money.

Dr. Sy is absolutely amazing I have been seeing her for 5+ years and I don think I would be able to find another doctor I trust as much as her. The staff is fantastic and very helpful when dealing with insurance or other issues. The biggest plus is the online capability to schedule appointments, talk to the dr, and see your personal history! I definitely recommend her!

Definitely finding a different doctor. First, they make your wait forever! Secondly I had a huge blood panel done and when I went in to talk to her about my results, she basically told me I could have a heart attack! She’d talk to me like I was 5 years old, which was extremely annoying and unprofessional. I told her I was pregnant and she told me was progesterone levels were extremely low, and most likely I’d have a miscarriage! Seriously? She took my blood before I ovulated! So of course it was low! She stressed me out so much, I cried non stop. She said all I could do was use cream from Mothers and that they don’t make prescription progesterone! LIE!!! She LIED! They do make it! Several forms! She just wasn’t willing to prescribe it! Did she want me to miscarry??? She believes in her «Vitamins», that she tries to sell you every single bloody visit!!! I don’t care what her beliefs are in prescription meds, that’s my body and my baby she’s messing with!!! Pisses me off so much! NEVER AGAIN WILL I SEE THIS WOMAN! HUGE MISTAKE! Patients beware!

I am so happy to have found Dr. Sy, from the moment of my first contact with Luchia her receptionist I felt the caring attitude of this practice.
Luchia has spent a lot of time arranging and rearranging appointments for me, finding time for me when I had an emergency and always calling me back if a cancellation occurred; I know that she deals with illness all day but I feel a genuine sympathy and caring from her.
Dr. Sy’s nurse was also a pleasant surprise, another caring lady, calm efficient, I had no problem explaining my woes to her/​
Dr Sy as everyone has remarked is as a Dr. should be, very thorough, knowledgeable and interested in your problems and she has no problem referring you to the specialist care if you need it. It was a bonus to me that Dr. Sy was an osteopathic doctor (two specialists for the price of one) I booked an osteopathic treatment and she was very gentle too.
I feel as if I hit the jackpot, as everyone knows it is so hard to find a good doctors and this office is as good as it gets. Thank you all.

I’ve been going to Dr. Sy for over four years. I even continued to go to her despite the fact that her location moved and is now 25 minutes from my office. It’s not easy to find a good Doctor and the drive is worth it.
Dr. Sy is very thorough and has a good bedside manner. She often attends conferences to stay updated on new practices, research, and technologies. She doesn’t just give you test results, she takes the time to explain what they mean and answer any questions. When she’s with you, it’s clear that you are her priority and she doesn’t seem rushed or distracted.
Her office has an online portal so you can book your appointments online, get your test results or other medical records, pay invoices, email the staff, and more.
The front desk is always very thorough and friendly. I’ve never had any issues with billing. They always try their best to squeeze you in if it’s important, and if not, they will talk to Dr. Sy about your issue so they can try to work something out.
They don’t over book so it’s very rare to have a wait long to see the Doctor.
I highly recommend Dr. Sy for your general doctor, as well as adjustments for any musculoskeletal issues since she is also a DO.

Dr Sy is a soulful, caring and loving Doctor. It is just that simple. She is human that cares about other humans.

Dr. Sy is great! She takes the time to explain things in detail and answers all questions you may have without feeling rushed (like other practices do). Meredeth at the front desk is helpful and I’ve never had any issues with scheduling. Average waiting time in her office is about 10 – 15 mins. If you’re not patient then schedule first thing when she opens or last appointment for the day. You wont’ wait long. Overall Dr. Sy is kind, caring, funny, and makes you feel very much at ease. Highly recommended! 10 STARS! :)

Dr. Sy is awesome and always takes the time to answer any questions I may have. She’s nice and seems to care, not like other doctors I have had. I started going a couple years ago in Irvine and now that she moved locations, it’s a little out of my way, but it’s worth going to someone you can trust and be open to. Also, I love the staff there! They are super nice and understanding. I was running late to my appointment at the end of the day and they still let me keep the appointment on a Friday afternoon! Would definitely recommend. Yes, there might be a wait at times during peak cold/​flu season, but come on… that can happen at most doctor’s offices!

Makes you wait a very long time.
