Three top mutual fund executives have quit Firstar Corp. in the wake of  a major reorganization. 
Geoffrey G. "Rip" Maclay Jr., brokerage chief at the $14.3 billion-asset  Milwaukee banking company, resigned Jan. 1, officials confirmed. 
  
As president of Firstar Investment Services, Mr. Maclay oversaw a 475-  person brokerage sales force - one of the largest in the banking industry. 
Also out are Mark A. Kimla, an assistant vice president who managed the  bank's $2.6 billion-asset proprietary mutual fund family, the Portico   Funds; and Thomas Hatcher, a first vice president who oversaw the back-   office services that Firstar sells to mutual fund companies and employee   benefit plans.       
  
The resignations came in the wake of sweeping changes in Firstar's  investment products sales and management strategy - moves seen by industry   observers as an effort to pump fresh life into a business that has been   hurt by the market slump.     
Firstar and other banks "have done a poor job of building up a sales-  oriented culture, and maybe this is a way to change that," said Geoffrey H.   Bobroff, president of Bobroff Consulting, East Greenwich, R.I.   
The changes at Firstar can be traced directly to a plan implemented Jan.  1 by executive vice president Michael J. Bills. All three executives who   quit lost significant authority in the shakeup, Mr. Bills acknowledged in a   telephone interview.     
  
Under the plan, the functions of the company's trust, brokerage, and  securities service units were streamlined, and the Portico Funds' five-   year-old distribution agreement with Sunstone Financial Group, Milwaukee,   was scrapped.     
These developments came on the heels of a decision in December to impose  sales fees, or loads, on retail shares of the Portico Funds. The no-load   strategy, a rarity at banks, had been unpopular with Firstar's brokers, who   preferred to sell funds for which they could receive commissions.     
In the restructuring, Mr. Maclay, the former brokerage chief, lost  responsibility for Firstar's bond underwriting duties. These duties were   transferred to Firstar's trust subsidiary.   
Dana Russart, who previously ran marketing for the Portico Funds,  replaced Mr. Maclay as president of the brokerage. 
  
A unit headed by Mr. Kimla that had handled shareholder servicing for  the Portico Funds was combined with another Firstar unit that sells this   service to other mutual funds. Mr. Kimla's job was eliminated as a result.   
Management of fund administration and custody services was taken away  from Mr. Hatcher and split between two trust executives, Robert L. Webster   and Joseph S. Quinn.   
"It was apparent that Rip (Maclay) and the others were not happy with  their new roles at the bank," the executive said. "It was basically a new   guard pushing out the old."   
Reached at his home in Milwaukee, Mr. Maclay declined to comment on his  departure, saying only that he wanted "to look forward and not back." 
Mr. Kimla and Mr. Hatcher could not be reached for comment.
In severing its distribution contract with Sunstone, Firstar has opted  to handle internally the job of marketing the Portico Funds to the branch-   based brokers.   
Its new distributor, B.C. Ziegler, West Bend, Wis., is known as a "paper  distributor," meaning it manages distribution contracts for the bank, but   little else, fulfilling only the minimum requirements of the Glass-Steagall   Act.
