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.
