Dawn Aponte, the Dolphins’ executive vice president of football administration since 2010 and one of the NFL’s highest-ranking female officials, has left the organization to be an executive in team owner Steve Ross’s RSE Ventures.

Aponte served as the team’s top contract negotiator and support administrator for the Dolphins for years, though her role had been diminished in recent months as the team reshuffled its front office.

At RSE, a sports entertainment and technology firm, Aponte will be an executive working in business development.

“I’ve been in this league for over 25 years and doing a lot of the same stuff for close to 20 years now and we were talking about different ways of expanding my skill set and using my experience in a away to continue to develop and grow,” Aponte said Tuesday morning.

RSE President Matt Higgins said the company will take advantage of Aponte’s “unique background” involving law, contracts and team administration to build the company. One example he gave was expanding the company’s venture into drone racing.

Aponte was brought in by Dolphins owner Steve Ross during Bill Parcells’ regime, reached a public high-water mark of attention during an organizational rift between coach Joe Philbin and General Manager Jeff Ireland and saw her voice diminished in the organizational changes this past off-season under vice president of football operations Mike Tannenbuam.

Aponte was in charge of salary-cap administration and contract dealings for much of her time. But her role went beyond that in essentially handling administrative work so the coach and general manager could concentrate on football decisions.

During the infamous “Bullygate” situation in 2013 involving Jonathan Martin, Aponte helped synchronize the league investigation with the team. She also became a counselor to Philbin, siding with him as his relationship with Ireland deteriorated during that season.

Aponte recently has been rumored to be taking jobs inside the NFL (as vice president of football operations) and with the Detroit Lions in a front-office role.

Aponte called her 6 1/2 years with the Dolphins a “great experience.”

“I’ve been involved in a ton here,” she said. “I got to touch every aspect of football operations.”

As far as being one of few top-ranking female executives in team sports, Aponte said, “I never characterized myself as one of few women or ‘the highest ranking woman,’ whatever you want to call it. It was about continuing to develop and grow for me. I feel I not only had a great 6 1/2 years with the Dolphins but 25 years in the league.”
