Sentinel Investments has reorganized the portfolio management teams of its four mutual funds, company officials announced Thursday. 

With Elizabeth Bramwell, lead portfolio manager for Sentinel's large cap growth team, scheduled to retire on March 31, Senior Vice President Betsy Pecor and vice presidents Carole Hersam and Matthew Spitznagle will take  over management of the Sustainable Growth Opportunities Fund, which will be renamed the Sustainable Mid Cap Opportunities Fund.

Led by Pecor, the team has worked together for more than six years and has a collective 46 years of investment experience. The new management team will maintain the fund's focus on sustainable investing, which includes environmental, social and corporate governance screening, according to Sentinel.

Senior Vice President Jason Doiron will be added as a portfolio manager to Sentinel's Balanced, Government Securities and Short Maturity Government funds. An 11-year industry veteran and risk specialist, Doiron oversees fixed-income and derivatives management.

All management changes take effect March 29.
