I've read stories that Paley can come across as a little cold, unconcerned, and distant. And the anecdote you shared, honestly just made me want to pick him more. The fact that he handled the embolism so well and that the patient recovered is a sign that he can keep things under control.
Is the dude trying to make money? Yes, of course, and I don't expect him to be my daddy. I don't even expect to have a personal relationship with him. He has an entire institute overseeing the process of limb lengthening.
But by this very token, I do know that his quality and his service are great. You do not get to his status by being careless. He is in the business to make money and to provide good service. You get what you pay for.
Imagine that fat embolism had happened in a facility that wasn't so well prepared? In a random surgeon in India or Ukraine's office who was doing LL for the first time? Do you think they would've been able to address the issue as efficiently, do you think the resources and staff they would have on hand would be educated and familiar with the issue to treat you properly?
Guichet is much cheaper but he only does femurs. He does seem to be more personal and concerned with recovery from what I read. But the diaries I've seen from Paley have so far seemed more reliable and professional than what I've seen overall with Guichet.
Remember, you're not just getting the doctor alone. You're paying for the staff, the hospital, the nurse treatment, etc.. The doctor himself is just a small piece in a big puzzle to getting LL.
I feel like with all that considered, ignoring price, tthere's no better place than the Paley Institute to get LL. They are the most advanced and the most prepared for LL, and have even innovated in the field many times.
