Constantine is one of our tallest donors: he has a long, lean physique, with a swimmer’s build of broad shoulders, toned arms and muscles and a slender torso. Constantine is uniquely handsome, with an oval face, slender nose, bright blue eyes, and a full, wide smile. His handshake reveals big, strong hands and a firm grip. He played multiple sports through high school and college and stays in great shape by maintaining an active lifestyle outdoors.

Constantine has a very analytical, intellectual and thoughtful outlook on life; he has a postgraduate degree in Chemical Engineering, and excels at math and critical thinking. He talks openly about the challenges of immigrating to the US at an early age, and his desire to constantly be learning and exploring new experiences has made a wise, disciplined, and open-minded individual. Constantine is a great mix of someone who is very smart and practical, while also showing a sensitive, fun, and caring side. Constantine would make a great donor for any family!

Genetic Testing

Over the years, we have expanded our genetic testing of donors as genetic knowledge and technology have advanced. As a result, not all donors have been tested for the same conditions or with the same methods. All donors have undergone genetic testing for Cystic Fibrosis, Spinal Muscular Atrophy and Karyotyping.  However, many donors have had more extensive testing performed.

This donor has been evaluated for carrier status of the listed conditions. A negative result reduces, but does not eliminate, the likelihood of the donor being a carrier. If you are a known carrier of a genetic condition please contact us, and we will provide a copy of the donor's test reports to your physician and/or genetic counselor.
