In addition to SDN, you might want to approach your own school's pre-med club, or pre-med advisors or career counselors for mentoring assistance - especially if you're interested in meeting with a local mentor, face-to-face.
If your school also has an AMC, you might want to contact the AMC with the same types of questions.
Some clinical professors at AMCs are happy to provide occasional (but valuable) mentoring to dedicated students. Many of them are "voluntary" professors who are affiliated with different departments of the AMC. These voluntary professors often have busy private practices, and teach courses at the medical school or at the AMC. Many of them enjoy mentoring students - after all, they're already contributing their time and knowledge as a voluntary professor (for little or no payment). Feel free to converse with more than one professional (including male and female), to obtain different perspectives.
Thank you.
