Spent time to explore my husband’s concerns, offered his assessment & explained a plan for a solution. We left the appointment with optimism for a solution!

Dr McMahon has been very helpful to me while I’m dealing with my health issues.

Y’all demonstrated professionalism, restraint, and patience given my inability to arrive on time. Thank you for fitting me in.
I am relieved to find out that this sounds like a win-win. Not traditional surgery, so less invasive-ness (news to me), and, if successful looks to make an outsized good impact.
My misadventure Tuesday required me at some juncture to let you know that I would not be able to make the appointment. I had to resort to leaving a message. I assume perhaps incorrectly the message never landed where it needed to land.
If I can be of any help (other than refining my use of public transport) in providing details so you have a better grasp regarding what went wrong here, such / communication works better, just ask me.
