OPINION OF THE COURT

Carlos Baez appeals his conviction and sentence after pleading guilty to conspiracy and distribution of more than 1,000 grams of PCP and 500 grams of cocaine within 1,000 feet of a school. 1 His counsel *380 filed an Anders brief 2 and a motion to withdraw. Although granted three time extensions to file a pro se brief, Baez failed to file his own brief.

I.

Carlos Baez participated in the organized sale of cocaine and PCP on the 600 block of West Clearfield Street in Philadelphia. Supervisors like Baez distributed cocaine and PCP to the sellers, and collected the proceeds from them.

In police surveillance from January to March 2000, Baez was observed supervising sellers and collecting money from them, and retrieving cocaine from the storage locations. Baez himself made several sales to a cooperating witness, including 13 small jars of PCP sold on February 25, 1999, 2.565 grams of cocaine sold on February 29, 1999, 6.113 grams of cocaine sold on March 15, 2000, and 6.69 grams of cocaine sold on March 16, 2000.

On March 16, 2000, police arrested Baez and several co-conspirators on the 600 block of West Clearfield Street. They also executed search warrants for residences at 614 West Clearfield Street and 3108 North Sixth Street, from which Baez had been observed retrieving drugs. The police found significant quantities- of PCP and cocaine. At the time of his arrest, Baez possessed keys to 614 West Clearfield Street.

II.

The government calculated, based on various seizures and witness accounts, that the conspiracy sold at least 38 grams of PCP and 35 grams of cocaine each day during the course of police surveillance, from January 12 through March 16, 2000. The presentence report, after adding the quantities seized on March 16, 2000, determined that the total quantities for which Baez was responsible were 2,592 grams of PCP and 2,472 grams of cocaine. The report noted that the government fixed a higher quantity of PCP based on other seizures, but stated that the offense level would be unchanged even with the additional PCP included.

Factoring in a three-level increase due to Baez’s managerial role and a three-level reduction for acceptance of responsibility, the pre-sentence report recommended an offense level of 36. With a criminal history category IV, based on several prior offenses, the report fixed a sentence range of 262-327 months. Other than the heightened leadership role enhancement, Baez did not object to any of these calculations.

III.

At sentencing, the District Court adopted the lower guideline range recommended by the plea agreement, in which the parties stipulated to a two-level rather than three-level increase for leadership role. This lowered the guideline range to 235-293 months. Defense counsel advocated a sentence at the bottom of that range. The court agreed and imposed a sentence of 235 months imprisonment.

As noted, defense counsel filed an Anders brief. We have independently reviewed the record including the Rule 11 plea colloquy and the legality of the sentence imposed. We hold the plea was validly entered and the sentence was legal. We see no other possible errors.

*381 For these reasons, we will affirm the judgment of conviction and sentence.
