    BEWARE: Horrible Doctor and fraudulent activity.I received TMS treatment from Dr. Marsella at the beginning of 2023. He ensured me before beginning that my insurance would cover everything and pressured me to get started before receiving confirmation from my insurance. I was told that his team would handle this whole process.3 months pass and I find out that they havn't even begun making a claim yet. It has now been almost a full year since beginning my treatment, no one from his billing team … More will respond to me and he has stopped responding himself to my requests for my EOBs.On top of this it was the worst medical experience in my life in terms of Dr. Marsella's professionalism. We were supposed to have a meeting every two weeks to evaluate my progress. Every single time, and I mean EVERY time, he would miss the meeting and message me 45 minutes later if I could do it right now.We only met once in our initial meeting and to conclude my treatment and begin new treatment. I told him only 30 minutes was necessary. He was 30 minutes late of course, told me that since I had a good week after the treatment that I my depression was cured(I was later diagnosed with Bi-Polar type 2) and then charged me for a full hour. When I was hesitant when he wanted to charge for the full hour he made a big deal about it and tried to make me feel bad about it and guilted me into it.All in all, the worst medical experience in my life. I am currently in talks with a lawyer as this company is obviously committing insurance fraud or is at least negligent enough to be accidentally committing insurance fraud.I would steer clear of this company, Dr. Marsella clearly has no care for his patients whatsoever.

    Trying to be reimbursed for a covid test done in 2021. The insurance paid them 6 months ago, and they do not reply to my emails, do not return any phone calls. Not sure if they expect me to give up the money. But is not going to happen!!!!

    This is the best option for pre travel testing. There was no stress, no drama.....just GENTLE testing and fast results. Josh Lopez was very kind to this stressed panicking traveller just 6 hours from a transatlantic flight! Thank you Josh

    This is the best place ever for testing !!! The staff are amazing! Theyre professional and super kind they can’t do enough for you and are always making sure you’re attended to !! Don’t hesitate and book there !!
  • Avatar D Brown ★★★★★ 3 years ago
    For $150, everything about getting a Rapid PCR Test with results in 10-15 minutes was easy and efficient. Sample is taken as a dual nasal swab and tech made it not too uncomfortable at all. Location is easy to find and parking does not seem to be an issue. Once you enter the building go right past the elevator and then all the way to the back where you will find the simple office and lab setup. This is definitely the best lab overall that I have found at a reasonable price that is convenient to the … More Ft Lauderdale area.
  • Avatar C E ★★★★★ 3 years ago
