S. Natasha Gillis, Esquire

Attorney at Law

S. Natasha Gillis, Esq. is a business attorney whose practice area focuses mainly on transactions, contract review/drafting and counsel.  Natasha has provided legal guidance to a range of medical and dental practices as well as numerous service-based businesses spanning a range of industries including government contractors, pet services, financial advisors, accountants and more.  Natasha enjoys serving as the go-to attorney for numerous businesses.

Natasha's work includes business acquisitions, commercial real estate purchase and sale agreements, business succession planning, commercial lease drafting/review, entity formation (mainly small and professional corporations/limited liability companies) and drafting/reviewing and counseling clients on various other contracts for businesses at all stages including employee agreements, independent contractor agreements, non-disclosure agreements, non-compete agreements, purchase agreements, promissory notes, buy-sell agreements and more.  

As a Northern Virginia native, Natasha graduated from George Mason University magna cum laude with a Bachelor of Arts in Government and International Politics, concentrating on Political Theory and Law and minoring in English Non-Fiction Writing and Editing in 2006.  Upon graduating, she attended Howard University School of Law where she served as a student attorney in the Civil Rights Clinic and obtained her Juris Doctor degree (J.D.) in 2009.  

Natasha spent two years working with the Civil Rights Clinic where she provided pro bono services as a student attorney to represent plaintiffs whose civil rights were jeopardized.  It was during this time that the healthcare industry first sparked her interest. She advocated for a skilled African American obstetrician who was discriminated against and prevented from delivering a baby in a local hospital exclusively due to his race.

Purchasing dental practice
5.0 stars

"Natasha had already lots of experience in procedures for purchasing the medical and dental practice. She was honest and straightforward legally and ethically in giving me advice from the start to the finish. She explained the advantages and disadvantages of the options and provided continuous information and quick response on the status and actions of the issues. She also provided copies of all correspondence and documents related to the my matter, and protected my interests and advised on my concerns when making important decisions. I chose the right attorney to work with me. I strongly recommend Natasha as your lawyer for your future. Now your turn and good luck!"-- Dr. Jung Oh, D.M.D.

Associate (employee) agreement review

5.0 stars

"Natasha is an excellent lawyer and I enjoyed working with her. She helped with my contract review/negotiations for an associate position as a pediatric dentist. She was very thorough, available to talk things over in a timely manner (she is very easy to reach during and after business hours), and helped me advocate for my best interests. She took time to explain the nuances of dental contracts in a language I could easily understand. She addressed all my concerns, never rushed me or pressured me, and always had my best interest in mind. I plan to use her services in the future and would highly recommend her to other dentists. She allots evening hours to talk with dentists which is extremely convenient!"-- Dr. R, D.D.S.

Commercial lease review

 5.0 stars

"Natasha is wonderful to work with! We are starting a new business and she was very helpful in explaining how to navigate commercial leases and gave valuable advice on starting our business and cautioned us on what to be careful of. She was kind, courteous and listened to our issues very carefully. If you're looking for an attorney who truly cares, I would highly recommend Natasha!"-- A.G.
