To give us an idea of the overall feeling of your brand, let us know which styles you lean towards
I didn't choose a color palette, because I want to see what you all come up with. Keep colorful in mind, rather than sticking with one color.
See attachments below of logos that I like. I would also love to see different versions of the letter "M".
I would like to stay away from stethoscopes or doctors with a searchlight on their head.
Keep simple in mind, most people will only see this logo as an App icon.
