   MEMORANDUM

Dennis R. Penfield appeals from his guilty plea conviction and 240-month sentence imposed for possession with intent to distribute a substance containing a detectable amount of methamphetamine, possession with intent to distribute more than 5 grams of methamphetamine and possession with intent to distribute more than 50 grams of methamphetamine, all in violation of 21 U.S.C. §§ 841(a)(1), (b)(1), and 851.

We decline to review Penfield’s ineffective assistance of counsel claim because such claims are generally inappropriate on direct appeal. See United States v. McKenna, 327 F.3d 830, 845 (9th Cir.2003) (stating that ineffective assistance of counsel is more properly raised on collateral attack under 28 U.S.C. § 2255, unless the record is sufficiently developed or there is an obvious denial of adequate representation).

We dismiss Penfield’s challenge to his sentence in light of the valid appeal waiver. See United States v. Nguyen, 235 F.3d 1179, 1182 (9th Cir.2000) (stating that an appeal waiver is valid when it is entered into knowingly and voluntarily); see also United States v. Cardenas, 405 F.3d 1046, 1048 (9th Cir.2005) (holding that the changes in sentencing law imposed by United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), did not render waiver of appeal involuntary and unknowing).

DISMISSED.
