President & Founder

Ashley and Ari Haseotes are the founders of One Mission. They are the parents of three children. Their eldest child, Nicholas, was diagnosed with AML leukemia at the age of seven months. Nicholas was treated at Children’s Hospital Boston and at St. Jude Children’s Research Hospital. It was their family’s journey with pediatric cancer that inspired them to create One Mission. Ashley currently serves as One Mission’s President and as a director on their board. Mrs. Haseotes worked for a large Savings and Loan Institution for eight years prior to having children. The sales experience she gained while working as a wholesale mortgage representative has given her the tools to develop and grow One Mission.

Ashley, Ari, and their family reside in Metro West.

As a parent of a child treated for Stage 3 Hepatoblastoma (a rare form of liver cancer) at Children’s Hospital Boston, Kerry brings a knowledge and insight to One Mission that only one who has gone through such an experience can bring. She is keenly aware of improvements that can be made which would greatly benefit both the children and the families being treated for pediatric cancer.
Kerry is a Marketing Director for a leading financial services company with nearly 20 years of direct marketing experience. She has a Bachelor of Arts degree from Roger Williams College as well as a Master of Arts degree from Emerson College.

Gina M. DeAcetis Powers
After a third child close to Gina was diagnosed with cancer, she felt called to become involved with One Mission. While visiting with these children and their families during treatment, Gina was drawn to Ashley Haseotes’ vision for One Mission of improving the day-to-day life of children battling cancer.

Erika Siegal
Erika Siegal was born and raised in central Connecticut. She received her Associates Degree in Science in 1998 and moved to the Boston area to complete her studies in Art Therapy at Emmanuel College. In 2001 she was engaged to be married, and decided to take a position in her fiancé’s family business. A few short years later, her most inspiring role would be that of wife and mother. Erika has two children, a son 4, and a daughter 2. Erika’s healthy, happy, beautiful children are what led her to One Mission. Erika met Ashley Haseotes, founder of One Mission, on a fateful day while waiting for her daughter to have her vaccinations at the doctor’s office. Meeting with Ashley and hearing her story changed Erika’s perspective and outlook. She would never be able to perform her role as wife, mother, and business partner the same way again. This chance meeting was the beginning of a wonderful friendship, as well as a partnership to help make a difference in the lives of pediatric cancer patients and their families. Erika is very proud of her role as a director for One Mission.
