When Christian is not meeting with clients or out in the field working on projects, he is with his wife and two daughters. He enjoys outdoor sports winter and summer. During the winter months, he is often away at conferences, learning about new industry-related techniques, best practices and trends. He is passionate about his work and believes that every element of residential outdoor living spaces should be given as much consideration and care as when designing and building a house. Similar to every room in a house, every area of the yard should serve a function.

Sedef is the glue that holds lines of communication open between the clients and the rest of the company. When Sedef is not in the office, she is probably busy with her two babies or doing hot yoga. She loves summer even if this is her busiest time of the year. She often states that she misses the heat of the Mediterranean.
Last fall, Sedef attended the Green Roof Healthy Cities Conference in San Francisco. She is looking forward in obtaining her (GRP) Green Roof Professional accreditation sometime in the near future.
