How likely are you to recommend Invictus Clinic - Ketamine Treatment Atlanta?
“I've had six treatments l here & I must say. Brandon (he doesn't want you to call him doctor, because he doesn't want the clients to feel like they are looking up to some kind of guru..this is my observation) His staff is awesome Mrs.Katie & the others. ALet's talk a little about the shop... they have those heavy weighted blankets, which I love😍 mini fans on top of good air conditioning, velvety padded eye masks, those mellow sound machine thingies, movie theater recliner chairs in each room! Simply put, they really, really take care of you🥳🤩🤣 on one of my visits, they had a high end therapist visiting each room and talking through issues, problems and needs if the patient desired😂 This treatment is not for the faint of heart, because Brandon is committed to making sure you get well😂😁I highly recommend this particular clinic!!”
“Elite! Dr. Brandon and Katie are truly the most remarkable individuals I have ever encountered! Words can not express how immensely grateful I am to have received this life-saving treatment! Thank you Dr. Brandon and Katie for making it effortless for me to trust both you when I had ran out of options and lost all hope. Thank you Dr. Brandon for not only saving my life but also for making it worth living! Because of Invictus I can now confidently say that, I am the captain of my soul.”
“I cannot begin to say how thankful I am for Dr. Brandon and Katie. My husband started the treatments first, and after seeing how amazing they were with him and the changes that I saw, I decided to get the treatments for myself. It's been night and day, and Dr. Brandon lays things out in easily understood terms. He's caring and funny, and I have always felt as if I were in the best of hands.”
“Dr Grinage is one of the best attending physicians I've ever experienced. We were there for therapy back in March and wife just got her booster. We absolutely love and are grateful for the gift that Dr Grinage and everyone at Invictus is giving to the world. Highly recommend but remember K is the beginning of the work!”
