Sex: MaleLocation: GreeceTreatment Year: 2023Length of Stay: 60 days Conditions Treated: Cocaine/anxiety/depression. Unfortunately after several years of abstinence I relapsed in September (2022) during a stressful period, culminating in a very large dosage of cocaine in the week before discovering Marieva. My supportive and long suffering wife insisted I was in a crisis and we looked around for immediate patient intake rehab clinics the day afterwards. I have had experience with rehab centers in the past (in the UK) and I must say this experience at Marieva is nothing like those. First of all, she puts her heart and soul into her work. You are not a client; you are a patient/friend. The actual support network is conducted by Kalliroe: Psychiatrist, Nutritionist, Personal Trainer, Masseur, Pathologist. But Kalliroe is the Alpha and the Omega and runs the show. She monitors you and gives you feedback on your progress on a daily basis.The fact that the institution is only 1-1 is very special. It means ALL the attention goes onto you and she will not rest until you are 'fixed'. She makes you feel unique and has the mental space to focus only on YOU. It’s like being in a supportive home. The fact that I was allowed to work (for a few hours a day) remotely relieved me immensely as obviously I had concerns with how my job would be effected. She even spoke to 2 or 3 of my team managers and smoothed out any concerns that might have been developing there from a legal/procedural point of view!In short, Kalliroe goes above and beyond what is expected from a therapist. The fact that she is a professional Pharmacologist gives different insights to all the other therapies I had tried in my life before, but the team is on hand to give a holistic view and develop the story of the underlying issues we may all have (Anxiety? Depression? Aggression/violence?).I can tell you that right now I feel confident to face the world again. My future feels bright again.

I am a young man from Syria and I live in Athens. I have a family and two children. I have been involved in drugs (cocaine) for about two years and I have made many attempts to quit drugs because it started destroying my life and my family by following up on many doctors and specialists, but to no avail, until one of those close to me told me about the Marieva Center under the supervision of Ms. Caleroy, and indeed I went to the center, and from the moment I arrived, I was suspicious of hope. The staff and Ms. Caleroy were very kind and took my decision to enter the center. I noticed a big difference after only a few days because of the wonderful attention from Ms. Caleroy and her staff. I felt that I was in my home and among my family because of the dedication to work and the medical and psychological follow-up and high luxury and indeed after one month I was able to quit cocaine completely, thanks to Mrs. Caleroy and her dedicated staff, and I did not feel that I was in a sanatorium. There were many activities, trips and high interest. After I left the center, Ms. Claroy kept in constant and daily contact with me by phone and in weekly meetings to check on the stability of my situation. Indeed, Ms. Claroy has brought me back to my normal life and my family. All thanks and appreciation for Marieva Center and for all the staff under the supervision of Ms. Caleroy. All words of thanks and appreciation do not express how much I thank this wonderful staff.

If you’re reading this then you’re probably be suffering with some sort of an issue (mental, drugs depression etc) that needs to be resolved. I had a drug issue and was very hesitant at first in joining a rehab center since where I live people usually have a stigma and a bad image of rehab centers.However, this isn’t a normal rehab center. Kalliroe took very good care of me and never slept just to make sure i was taken care of always, especially through the tough times in the beginning, and she always made me feel like I was at home and took care of everything for me.After I started feeling better she also took me some of the best cafes, restaurants and tourist attractions. I initially reserved for only 1 week due to hesitation, but I ended up extending another 2 weeks since I was having so much fun, until I had to return due to work but by the end it was like a vacation. Kalliroe and I have built a very good friendship and she still texts me most days to make sure I’m clean and to catch up, as she does with all her clients.Health is more important than anything, and without a healthy and clear mind you’re never going to accomplish any of your dreams & goals, trust me i’ve tried for too long. My advice is don’t think twice and take the next step to start a new chapter in your life.All i can say for myself is that this was the best decision I’ve ever made. I feel like a new person with a new second life.

My experience at Marieva Healthcare was one of a lifetime. I reached Marieva Healthcare because I had depression and anxiety disorder, which made me feel powerless, extremely sensible and pessimistic about my future. The CEO, Fragkou Kallirroe with her professional team surrounded me with love and affection. Following the right and personalized treatment for my condition, I began to feel strong and confident again. Kallirroe Fragkou is a very supporting and trustworthy professional with strong scientific studies and knowledge that approaches every person in a unique manner, that makes you feel unique. Marieva Healthcare is in a peaceful and cosy location, with a magnificent view, which relaxes you. Each treatment is personalised for your special condition. The food is delicious and tailored to your nutritional habits and needs. Completing my treatment and leaving Marieva Healthcare, I felt strong enough to continue my present life and to imagine my bright future with my family.
