Special kudos to…read morethe patient who brought their husband to one appointment for a "sanity check" and for his declaration that they would never go back. I endured four visits, though I knew after the first visit that this doctor lacks the qualities I needed, as a patient fighting a complex and damaging rheumatological disease. I continued seeing her because I wanted to be sure she wasn't just having a bad day and I desperately needed medical care as my rheumatologist had retired. Sick people in pain tend to be desperate and perhaps that's why I endured multiple visits. I found her to be continually stone-faced with an icy demeanor. So no, she wasn't just having a bad day and she didn't deserve me remaining open-minded about her. She actually seemed bored during my visits, and rarely responded to anything I said, making me feel that my observations and comments were a waste of her time. She provided no information about my disease. As kindness and compassion don't seem to be part of her standard medical protocol, I have to wonder why she chose rheumatology rather than radiology or another field where she could forego direct contact with patients altogether.

    I don't usually write reviews, but my experience with ARA has been so bad that I feel compelled to…read moredo so. This review is based on my experiences with the DC/K street office, the phlebotomy (blood draw) lab there and Dr. Shari Diamond. TL;DR: avoid this practice, particularly their DC office and Dr. Shari Diamond, at all costs. As relevant background, I received my graduate degree from a PhD program through a very reputable medical school where I attended the same classes with the medical students. Medical students then went on to clinical rotations at the hospital while my group did lab/research rotations. I have also helped previous employers gain CLIA certification, which is the regulatory standard for the labs that draw your blood as well as labs that process those samples. While I am not an MD, I know more than the average person about how things are supposed to function in these settings. I was referred to Alan Matsumoto at ARA by my rheumatologist in California when I moved to DC. Dr. Matsumoto is very reputable and appears to be at the forefront of research in rheumatology/immunology. My case is, according to my California doc, very alarming and unusual (and, therefore, quite scary). I couldn't get an appointment with Dr. Matsumoto (I'm not sure if he is still at the practice or not) so I ended up seeing Dr. Shari Diamond. I have seen Dr. Diamond four times, with each appointment worse than the last. At my last appointment I tried to have a discussion with Dr. Diamond about her attitude toward me, even trying to smooth things over by saying that I should have come in with written questions to avoid miscommunications because my condition is relatively new (~2 years since onset) and frightening for me and I get very nervous. Her response was imperious and truly awful. She appeared to fake my examination, skimming her hands lightly over the outside of my very heavy, puffy snow boots pretending to check for swelling that she would not have possibly been able to see or feel with the technique she was using, even if I hadn't been wearing the boots. Every time I have tried to tell her my history and relate that to changes I am experiencing with the pain and swelling that are hallmarks of my condition, she has interrupted me and very belligerently told me that any symptoms and elevated inflammatory markers I had in the past are irrelevant and there's nothing wrong with me now. As anyone with an autoimmune disease can attest, this response is antithetical and screams incompetence and/or a mentality that does not belong in any sort of front-line patient care. Even after I told her explicitly that my goal was to figure out what was happening with the progression of my condition, I was not simply seeking symptom relief, I did not need another anti-inflammatory prescription and the only drug that has worked for me so far is prednisone, she was cruel, dismissive and disdainful. At my last appointment, their phlebotomist drew my blood to check my inflammation levels and, I found out from the notes later, for "medication monitoring", even though I wasn't taking prescription medication for my condition. If you have been to a rheumatologist you have almost certainly had blood drawn and you know how that is supposed to work: the phlebotomist asks you to confirm your name, birthdate and perhaps other info. They will often ask you to review your info on the sticker labels before they are applied to the vials of your blood. This is because CLIA regulations require robust processes to ensure sample integrity throughout the process. None of that happened when my blood was drawn at this office. The phlebotomist did not ask me to review any labels or info and, after drawing my blood, walked out of the room with the unlabeled tube, ostensibly to retrieve the labels from a desk outside the door that could not be seen from the room. She was gone for much longer than was necessary for that stated purpose. I have no idea where she went or what she was doing with that vial. Even after that bloodwork showed elevated inflammatory markers, Dr. Diamond's response through a message in the patient portal was to prescribe the anti-inflammatory I had told her I did not want because is not appropriate for my condition and tell me to check back in 2 months. Perhaps I should have shown up to my appointments wearing a suit instead of jeans and sweatshirts which are my usual uniform these days since I no longer work in an office. Perhaps I could have garnered Dr. Diamond's respect by showing up with my degrees hanging around my neck and my W2s stapled to my forehead. Or perhaps she just shouldn't be practicing medicine. I hope that the partners at ARA will endeavor to figure that out.

    In line with some other reviews, I feel that ARA's billing practices are suspect. There was no…read moreclear diagnosis during my visit, so the dr. ordered an array of bloodwork, some to be processed in-office and some sent to LabCorp. When I asked ARA's phlebotomist whether the bloodwork processed in-house was more expensive than the vials being sent to LabCorp, she was uncertain. After taking 8+ vials of blood, she handed me paperwork to take to the front desk. She said she forgot to ask me to sign the last page prior to drawing blood, and to do so. This page was an admission that in-house bloodwork could very well cost more. I felt cornered into signing it in order to complete my visit, and I put faith in the ethics of the practice. Sure enough, I received a bill for $296 dollars for in-house bloodwork processing that my insurance would not cover. I received an emailed invoice with only the amount that was due. I called the billing office for a breakdown of the bill. I followed up with my insurance company (large, recognizable brand) who told me the medical practice had coded the bloodwork in a way that was not covered. The insurance rep said that if they had coded it as "routine" it would have been covered. They also said that the practice could void and resubmit with this coding, though ARA declined to do so. I cannot speak to the reason, and so cannot make judgments on this. I have since sent two unanswered emails to their billing dept. through their online portal to address the situation and called to speak to the business office, who denies seeing any messages in the portal (which I referenced by date and are still visible today). The representative said she'd bring them to the attention of the managers, but they would not consider any adjustments to my billing, only to training their staff to better communicate during visits. It has been weeks, and no one has addressed my emails/concerns. I'm left feeling obligated to pay this bill and completely mistrustful of ARA.

    I can enthusiastically recommend One Medical, which is owned by Amazon. And, no, I don't hate…read moreAmazon, so if that bothers you, take note. I admit, I was very skeptical, but the practice is so efficient and friendly, I'm recommending them to the Yelp DC community! And I"m very fussy about health care (I'm from Boston, what can I say--it's the best city in the US for health care!) The one item I was hesitant about--it's a common problem in the DC metro area--is you won't get an MD, you'll be seen by a Physician's Assistant. But--I lost my primary care MD 5 years ago, so started calling practices, GW MFA, etc., a year ago to find a new MD. Forget about it. I started calling again recently, hoping there were doctors available. Nope. There is NOTHING out there--I had estimates of waiting times of several MONTHS for an appointment with an MD. No one offered an appointment with an NP or a PA. A few places wouldn't even put me on for a wait list appointment! It's dire. I had no choice but to sign up at One Medical, which btw was recommended by two friends with high standards for doctors. There is another potential issue, that it's only general practice, no specialists. But they do a lot of the requisite tests, blood tests, etc. I already have my specialists, so it's not a problem for me. And my PA is excellent. She is pretty young, but very well trained, very smart, and responsive. And you can tell she likes her job! More good things about Farragut Square OneMed. I"ve been several times since joining a few months ago, and I've NEVER had a wait. The front desk folks, the techs, the medical professionals? All excellent, very personable, and polite. What a change from some other DC medical practices! They take insurance--and if you're not insured, they will figure it out. Also, they are so tech forward, everything is very easy to accomplish, and not stressful. No waiting on hold! Again, what a change. Anyway, if you need a primary care MD, and can't find anyone, give one of these practices a try. If you don't like them, you can leave.

    I think One Medical has been a victim of their own success -- there are too many patients and you…read morecan never get an appointment now. The whole point of paying for it is supposedly so you can get prompt responses and next day treatment. At first, I could always get appointments same day or the very least the next day. Now to book a physical with my doctor, I needed to book 5 weeks out. To get an appointment for an illness, the next available on the app is over a week from now. A more traditional doctor, I could call and ask to be seen same day. But no one answers messages on the app anymore. I'm trying to switch practices but no one will answer me through the app how to cancel my membership. If you are looking for premium care and service, this is definitely not it anymore. PS: do yourself a favor and sort the comments by "newest first" -- you can pinpoint exactly when things went downhill. All the positive reviews are over a year old.

    I've never written a negative review before for any kind of business, but my experince here was so…read morebad that I'm writing to save others the grief of going through the same thing. Long story short, do not go here. I have a chronic illness that, given recent a recent deterioration in condition, requires regular infusions. I found Arise through a google search because my doctor operates in VA and the centers he regularly recommends are not close to me (I live in DC). I reached out to Arise and followed the steps I was given to schedule an initial infusion - which involved having my doctor send the order and sharing my insurance information. Several weeks went by and I didn't hear anything. I checked back and was told by the benefits coordinator that the insurance approval process was still ongoing. As things approached the one-month mark, I checked in with my doctor and he confirmed that the approval/scheduling process was taking an unusually long amount of time. Because of the severity of my condition, it is important to get these infusions scheduled as quickly as possible. After several check in calls from me, I received a call back from the benefits coordinator and she told me that insurance DID approve my claim, but that she couldn't yet schedule me, without explaining why. She said that she would call me back soon to schedule an initial appointment. Another week went by so I called back. The same benefits coordinator told me that she needed one more code. I asked why she didn't call to let me know, she told me it was company policy to go through the doctor. This didn't make any sense to me. So I called Blue Cross (my insurer) to check on what they needed and they told me they had no record of any approval request. The Blue Cross rep checked all three of their possible systems, and said there was zero record of any outreach from Arise. I called Arise back and asked to talk with a supervisor, and was sent to someone senior to the benefits coordinator. This more senior person checked my record and confirmed that no action had been taken over the past month - my insurance had not been contacted and there was no approval. This more senior staff member was apologetic, and said the company would look into what happened. In the end this was a month of critical time wasted, on top of the deep disrespect of being directly lied to. If this company's front-end administration is this big of a mess, I wouldn't trust them with the injecting of powerful drugs.
