    Wow, "Don't Believe The Hype" I just can't stay silent any longer while a good company and a great department are continuously and inappropriately maligned. I've worked in Quality Compliance for some time and have watched it grow and become a great team of people and managers.

    It's shameful that a person is using Glassdoor to continually say terribly unfair things about this group and Masimo. It seems every 4 to 6 weeks a previously bad review disappears and a new one appears (in what I assume is an attempt to keep the bad review at the forefront of Masimo's reviews) that pretty much says the same criticisms and calls out Quality Compliance specifically. When will enough be enough for this person? It smacks of the same "abuse and bullying" they are claiming they suffer. Quite frankly I don't believe their reasoning as it is inherently flawed and they have their facts incorrect.

    First, they keep saying if they didn't need this job or if it weren't for their financial situation that they would leave. Well "newsflash", let me point out that we are in fact in Orange County, California, which is the Mecca of medical devices so it seems to me that if they are in quality then they should be able to get another job quite easily, unless their poor attitude somehow spills over into interviews.

    Second, I don't know of anyone that's been forced to resign in Quality Compliance during the time that I've been here and if there are any personnel issues, HR has assisted in resolving them. Since I'm a manager in this department (there are 6 or 7 of us), I would know if anyone has been forced to resign so they in fact are making a false statement. There has been very low turnover in the dept in the past year and almost all of it was for career opportunities or life changes that people were making. Guess what, that's normal in industry. People move around. People change companies, it's part of life. Which goes to my 3rd point...

    People aren't leaving "on a daily basis because they can't stand the abuse and the bullying" or we wouldn't have anyone left. As managers, this team goes out of their way to ensure that their employees are shielded from some of the politics (again normal for any organization) and all of the employees on every level in Quality Compliance are more than willing to pitch in an extra hand when needed to get the job done. You don't always get that in companies and you certainly wouldn't see that in a company where the stated "abuse and bullying" are going on. This is a great team and you don't have that kind of dedication if there are bad managers, directors, VP's or a bad CEO for that matter.

    It really sucks that Glassdoor is being used as a form of corporate terrorism. Happily though, I've got just as much a right to post my opinion and experience at Masimo in the Quality Compliance group as "Don't Believe The Hype" does so here is my experience. Yes Masimo is growing and experiencing growing pains just like any other company. Grow up and be a part of the solution like the rest of us! At least we are trying. And yes we all believe in Joe's mission! If someone is working here who doesn't believe in that then they should probably look elsewhere for employment, plain and simple. He started this place, it's his blood sweat and tears as well as many of the other early people that gave up their time and energy to make this company what it is today so if someone doesn't agree with it, move along. As stated above, there are tons of medical device companies in SoCal, so why would anyone stay and if they are that miserable?

    As far as calling out complaints for increasing, when we sell more product year upon year and have more devices in the field, what would one expect? Is this person without reason? When we are selling $50 million more in product each year it is expected we take a few more complaints, nothing out of the ordinary there. They obviously don't really know any of the real details about our complaint rates. In fact I would say we are more responsive and quick to fix any issues because of the amazing team of engineers and management that we have. I have personally recommended several people to come work here at Masimo and yes in Quality! I don't do that lightly. My personal reputation is on the line when I do that and I wouldn't do it if I thought anyone was going to be abused. Yes there is a bully or two here. However, that is the world we live in today and I've experienced that in every med device company I've worked in. Again, people have to grow up, man/woman up and deal with them head on. These are NOT the majority of people here at Masimo. As in any other organization you have to take the bad with the good and deal with it.


    Continued from above: Lastly, if "Don't Believe The Hype" is using this forum to try to make a particular person or manager in Quality Compliance look like they are writing disparaging things about Masimo, shame on them. For someone to keep posting reviews such as this for the past 8 months, if their aim is to hurt this group whom they state are "smart hard working people" well congratulations, mission accomplished. Every time a bad review comes out people on this team, including myself, worry about their jobs, raises, bonuses, promotions, etc. "Don't Believe The Hype" isn't just terrorizing Masimo, they are hurting every person in Quality Compliance every day and THEY are making it a tough place to work, no one else. Shame on you. Masimo isn't doing it, Quality Compliance management isn't doing it, Joe certainly isn't doing it, YOU are. Look within because only you can help yourself. Shame on you.

    Cons: Nothing really, growing pains aren't always a bad thing, we are using them to learn and make the future better for the company.

    Advice to Management

    Keep up the good work and don't take the haters to heart! Focus on the positive and the company will continue to grow!
