Archived Ad: Recent grad seeks pre-med experiences

I am a recent Brandeis graduate where I was a triple major. I received a Bachelor of Science in Health: Science, Society and Policy, Biology and Hispanic Studies, with honors for my thesis. I am in the process of taking the MCAT and applying to medical schools, but I am first looking for clinical volunteer experience that enables me to interact with patients, shadowing opportunities where I will be able to interact with healthcare professionals and learn about their interactions with patients, and/or employment opportunities as a medical scribe, transcriptionist or secretary. I have office skills that I attained in my 2.5 years working in the office of The Arc of Massachusetts in Waltham, MA. I am able to use Microsoft Word, Excel, PowerPoint and Publisher. I am proficient in Spanish. I also have prior experience in entering patient information into a database from my clinical work with Global Medical Brigades in rural Honduras. In the triage station, I took down patient history, vitals, and symptoms, and I was able to shadow physicians in the consultation station, assist in the OB/GYN station, lead the education station teaching about personal hygiene, and fill prescriptions in the pharmacy. Prior volunteer experience includes being a Hospital Helper at Newton-Wellesley, a classroom volunteer through Junior Brandeis Achievers at Stanley Elementary School, a Health and Wellness Intern at the Chill Zone, a middle school rec program in Waltham, and an Undergraduate Departmental Representative for Hispanic Studies (as well as serving on the UDR council). I am wondering how to go about looking for these types of positions (aside from websites like Careerbuilder) and how to go about networking with former alumni.
