I've been a Defy patient for a few years. They are very good and can be expensive, especially for me the every 6 month blood work. Nurse Jill does my consultations.
I must say that their customer service is becoming hit and miss. I got a snarky email today because I hadn't had my labs done and they were overdue. The problem is that they never notified me that they were due until today. As much as I pay them, it seems like they could check their own emails to see if you've been notified or not before sending a less than friendly email.
UPDATE: I did receive an apology for the email after I responded to it. They are blaming their system and supposedly not having the right phone# which is odd as I've always had the same phone# with Defy and have received text lab notifications in the past.
