Hello Tobi,
I hope you are well. Thank you for your comments about the Dauphine Twin Quartz and Liroconite.
Like everyone around the world, I have been preoccupied with the pandemic. However in my situation, I cannot see patients and socially distance. It is just not possible and telemedicine is not the answer for every patient. This does drain about all the energy from the mind and body, but the only life I have known for almost 50 years.
It is great to hear from you and stay safe, it is far from over.
Regards,
Don
