Please be ware of this place!! It is a scam to just get money. Dont get fooled by the positive…read morereviews. I also ignored a similar review about money and still went there to get trapped. They book a "meet and greet" session for new patients. I asked them 4-5 times before the appointment, how much it will cost after giving all my insurance info. All of their team assured me that it will be 0$ co-pay for me as it is only a meet and greet where Dr. will just get to know you. Guess what, they billed my insurance 700$ after the appointment, out of which they are asking me to pay 300$. This is a scam. And the Dr. did nothing in this appointment, no advice/tests nothing, other than me sharing about my medical history and past test results and my concerns. I got to know that there are California laws against this, I will be filing a legal complaint Update: I called their billing office as Dr suggested in his response and told them I'd report them to the medical board. They said they will file the claim with insurance with a different code to see if they can bring the cost lower. You know what they did instead? They sent the bill to collections immediately. No warning, no attempt to resolve, no accountability. Just pure, disgusting greed and lies in every interaction. This place runs on lies, shady billing tactics, and a complete lack of ethics. And if you dare to speak up, they'll come after you. Because that is their business to suck up on your hard earned money $325 isn't going to ruin me -- but this kind of disgusting thug behavior is what unfortunately defames entire healthcare. I hope this "doctor" Iwahashi loses every patient who reads this. They don't deserve your money, your trust, or your time.

HORRIBLE doctor who does not care about his patients. He is a clear example of a specialist who…read moredoes not want to do anything for his patients and tries to kick off responsibilities to other teams even though he is assigned to treat my problem and specializes in the issue. While some people seem to have positive experiences with him, it seems that he reserves his professionalism for certain people and not others. Beware. He is unwilling to spend 5 minutes doing something that could change somebody's life for the better. I am undergoing treatment with him and other specialists for why I keep on losing my voice for weeks at a time. I simply needed accommodations for my hoarse voice and LOSING my voice for significant periods of time. This has significantly impacted my ability to participate in class. My voice is GONE. It can come back one day and be completely gone the next day. It is very normal to seek academic accommodations for a loss of voice. For example, if you are taking a language class, sometimes you need to push out your deadlines for presenting if you literally don't have a voice. My school does this through the disabled students department. And currently, consistently losing my voice has become a disability because I literally can't talk and complete some of my assignments. Many teachers ONLY accept accommodations through the disabled students program: informal requests are often denied. He is the first doctor I have ever met who has refused to provide any kind of letter simply asking for accommodations surrounding a lost voice--e.g. something as simple as "this student needs to have flexible deadlines as they often lose their voice. Currently I am not clear on what the diagnosis is, but I request flexibility for their voice loss. Their loss of voice affects them to effectively participate verbally in class, so deadlines may need to be pushed until they regain their voice." Instead, he sent a very rude and low-effort email saying that he is unwilling to write me an accommodations letter simply because he doesn't know what my issue is and disagrees with the other specialist. This is unacceptable. For example, let's say somebody has some other terrible, similarly disabling disease. It might take a couple of months for the specialists to agree on a diagnosis, but they could still be suffering and their ability to participate in society, work, school, etc. is completely affected. They should get accommodations. I'm getting diagnoses or medical opinions thrown at me left and right. Even if different doctors have different opinions, ultimately, one thing remains the same: I have lost my voice for almost 20 days in one month and continue to be hoarse or lose it altogether some days. Other people had recommended this doctor to me. I had high hopes. I have never encountered such an irresponsible, uncaring, and callous doctor before. I don't doubt that he is probably academically brilliant. I just think that he doesn't realize that taking 5-10 minutes out of his day to fill out a form could change someone's life for the better. Even more malicious: perhaps he does, and chooses not to because as a specialist, he is above this kind of work.
