    "Amazing editor. Retains writer's voice while improving writing flow and style." -- Upwork Client Upwork Top Rated Plus • 100% Job Success Score • 90+ 5-star Reviews The best writing is transparent; it does not draw attention to itself but instead helps the reader engage with the ideas and encourages them to continue reading. I specialize in editing academic and technical manuscripts to the highest level of professional writing. Your final document will have prose that is clear, concise, and flows. Besides editing, I am also a professional musician. My musical training and experience help me to understand the importance of rhythm to both music and written language. Musical lines use flow and rhythm to engage the listener and pull them along to the end. Sentences and paragraphs work the same way; the rhythm and flow lead the reader through the sentence, slowing on important points and moving forward to the next phrase. I have extensive experience as an educator, scholar, and academic administrator and have written a book, scholarly papers, grant proposals, curriculum design, instructional materials, and technical guides. I have served as a manuscript reviewer for several publishers, including Prentice Hall and Oxford University Press. I have been teaching writing at the university level for 21 years. I have also guided many students through research papers, theses, and graduate school applications. My students have been accepted into graduate programs at Harvard, UCLA, University of Chicago, Columbia, University of Michigan, and others. Continuing and long-term clients include: • SRI International (Stanford Research Institute) • Valiantys • AvidThink • James Lange, best-selling author and financial advisor • tech firms, management and technology consultants, professors, Ph.D. students, op-ed authors, websites, non-profit organizations, etc. More testimonials from Upwork Clients: "I've tried many different freelancers to edit/proofread my writing, and Robert, by far, is the best one." "Robert's product quality was expert level, and his turnaround time exceeded my expectations. I will definitely seek to work with him again in the future." "Robert is a very meticulous, patient, knowledgeable, and highly communicative editor. His edits and comments are helpful and insightful." "Robert delivered top-quality editing work for my website copy. It's obvious he is highly experienced. He was highly professional, efficient, responsive, courteous, and helpful. I would not hesitate to work with him again!" "Great communicator, delivered above expectations. Would highly recommend working with Robert when the project requires clarity of thought in addition to improved grammar. Thank you, Robert!" "Excellent work. Fast, thorough, impeccable." — Upwork client reviews
