    Luna was amazing start to finish any questions she answered really quickly… I also had questions about the surgery which she could tell I was very worried but she set up a consultation with Dr.Abdullah and they called me from Whatsapp video. Me feel at ease instantly explained everything… I’m currently 4 days post op first day in hotel I can honestly say I feel great I’m walking good etc any time I needed help I pressed the buzzer and nurses came straight away if I told them I need pain meds instantly came back.. And was pain free withing a couple of mins… You see lots of company’s on tik tok social media and they offer extra but I chose this as the only focus on one thing and you and your health is there main priority from inquiring to even post op so amazing! You won’t regret it believe me xx so glad I went through this team big thanks to Luna and Dr Abdullah…
