AS FEATURED IN






I enjoy coming here to learn more about trials and doing them and the staff are so nice. Everyone greets you with a smile. The over the phone questions and review of the study is very useful. Very open to questions and always thorough. The compensation is beyond amazing for both the benefits of the study that helps you and getting paid is a nice bonus. Would definitely recommend if you're new or old to doing clinical trials.
This is not my first time doing a study with Atlantia. I liked everything about it - topics of study, the high level skills of staff, and the very friendly environment. I will definitely do other studies with this company again.
I have never participated in a trial before, this company has made this such a positive experience. They are very professional and pleasant to work with. Everyone is friendly, knowledgeable and here to make you feel comfortable. The office is lovely and easy to get to. Great trial to be part of.
I have worked on other clinical trials in the past, but Atlantia is hands down the best. Very professional, very kind, and very knowledgeable.
So far everyone I’ve interacted with from Atlantia has been lovely. Very good with explaining each step and each subsequent appointment. Very flexible and understanding when things came up and changes had to be made to existing appointments. Overall only positive experiences here!
