""We have been with OSI Offices since 2015 and have been very pleased. Great location and wonderful staff, headed by Mumbi Thande. Our Foundation appreciates all the courtesies and consideration afforded us as a non profit organization serving the working poor of the District of Columbia. Positive Responsiveness, Quality, Professionalism, Value""

""I have been with OSI Management for over 4 years now. I did my research prior to selecting a virtual office company and OSI offered far more favorable options and price points than the other companies of both comparable and larger sizes did. In addition, OSI has the personal touch - from management to office staff - that I love. I have the options of mail services, office rental and also dedicated office space as my ever-changing needs require. I have recommended, and will continue to recommend, OSI Management! ""

— Melanie Mfume

""I started my small business with OSI Offices, and they have been more than just an office space provider – they’ve been like a guardian to my business. From day one, their team has motivated and supported me in every aspect of my entrepreneurial journey. It’s not just about having an office; OSI offers invaluable in-house resources, including connections with experts in tax, finances, and company formation. The affordability of their services, especially for such a prestigious K Street location, is unmatched. Having my business office at this address has built trust with my clients, giving my business a level of professionalism and credibility that only OSI could provide. I see OSI and its employees as my partner in my business journey.""

""I have been utilizing this space since August. All the staff are friendly and very helpful. The free coffee and tea and waiting room really enhance my experience. The location and rate for rental literally cannot be beat and trust me I have looked. I just wish that we had our own parking garage or discounted garage.""

— Mychelle Williams

""I rented from OSI for years and had a wonderful and supportive environment and experience with them. Highly recommend to anyone looking for the same. The staff are professional, welcoming, responsive, and reasonable. Much appreciated!""

When I needed a Washington virtual office space their prices were very reasonable and I was able to customize my payment plan so that I was only paying for the services I needed as a small business owner....not to mention the fast internet and wealth of tech services they provide to help me automate many of my processes...Great!!""

""I LOVE my office at OSI. I visited a few other places like Regus before I made my decision to go with OSI and I am so happy with my choice. Having the K Street address is priceless. The location is convenient for all my clients, easy to find and metro accessible. The staff on hand are friendly and helpful, especially Mumbi, the manager. I recommend OSI Offices to all of my fellow entrepreneurs.""

— Kiki Strickland

""I have been using OSI's service since 2015. The service is excellent. OSI was still open during COVID-19, and has not raised its price for many years. Highly recommended!""
