Im with Monash also, different doctor as well - and since its my first cycle i cant give you a proper opinion on which is better as i dont know any different to Monash, but like Megan has said I found my doctor first who is just exceptional and opted to go with whoever he was working with as i value him and trust him immensly. I think you should really feel comfy with your doctor as he runs the show when it comes to your health and your treatment, the nurses go by what your doctor has advised.
I am loving Monash though, they have been just awesome and their service is amazing, they make you feel really comfy - but like i said i dont know any better, maybe Melbourne IVF is better??

best of luck on your journey xx
