Keen eye for detail, I am a skilled project manager that has managed both small and large internal and external teams, including developing administrative and operational processes for offices and individuals. I am also a skilled editor/proofreader for all types of publications (research, editorial, social media), as well as a wiz with web research and data entry! Likewise, if you need an expert in Microsoft Office and Google applications, I'm your go-to! I have worked in a variety of industries: from government and non-profits to private sector and academic/research, so I am well-versed in a wide variety of subjects (most notably science, health, policy, and the arts). I am very dedicated to my clients, but do value work-life balance (which I preach to all of my colleagues and clients). I am available to work as needed in the early morning and evening hours 7 days a week.
