Local medtech startup AristaMD is undergoing an executive shuffle this summer after the loss of its founder and chief executive Rebecca Cofinas in June. This week, the company announced two promotions within the c-suite that will fill her vacancy.

Brooke LeVasseur, the company’s chief business officer, is being promoted to CEO. At the same time, Dereck Tatman, the company’s former chief commercial officer, will assume the role of president and chief operating officer.

LeVasseur has a background in health care and medtech product development, which the company hopes will help guide AristaMD’s efforts to penetrate the telehealth market. Before AristaMD, she served in executive roles at Sequenom and Veracyte.

Tatman, who has a background in corporate strategy, is also in leadership at COI Pharmaceuticals, the incubatorlike home to startups that receive funding from San Diego venture capital firm Avalon Ventures. Avalon is an investor of AristaMD.

Jay Lichter, managing director of Avalon Ventures, has been serving as AristaMD’s interim CEO since Cofinas' departure. Lichter will remain chairman of the company’s board. Additionally, LeVasseur will join AristaMD's board of directors.
