OPINION

Russell Giardina appeals his 151-month sentence for distributing fewer than 100 grams of heroin, arguing that the sentence is unreasonable. We disagree, and accordingly affirm.

Giardina has a history of drug offenses. In 2000 he pled guilty to delivering cocaine, receiving a sentence of approximately 12-24 months. In 2002 he pled guilty to *75 possessing heroin with intent to deliver it, and received a similar sentence.

After his release, in March 2003 (at the age of 23), Giardina committed the offense now before us: he sold .24 grams of heroin in the presence of an undercover police officer. He was indicted and pled guilty. At the sentencing hearing, the District Court determined that because Giardina was a career offender, the advisory Sentencing Guidelines range was 151-188 months. Giardina argued for a sentence below the Guidelines range because of his young age, the absence of parental role models in his life, his status as an addict, and his devotion to his friends, family and community. The Court noted Giardina’s significant history of involvement with drugs, however, and, relying in part on this history, sentenced him to 151 months’ imprisonment, at the bottom of the Guidelines range, as well as 3 years’ supervised release.

On appeal, Giardina accepts that the District Court accurately calculated the Guidelines range and considered the pertinent 18 U.S.C. § 3553(a) factors, but argues that the 151-month sentence is substantively unreasonable. 1 We disagree. Giardina’s age, lack of a role model, status as an addict, and devotion to family and friends, though relevant, must be considered along with the need to afford adequate deterrence of criminal conduct and protect the public from further drug dealing by Giardina. See § 3553(a)(2)(B), (C). He has twice received short sentences for drug crimes, and these did not prevent him from continuing to offend. The District Court concluded that a longer sentence was therefore necessary, and the mitigating circumstances are insufficient to render that conclusion unreasonable. See Bungar, 478 F.3d at 546 (refusing to “find that a district court’s failure to give mitigating factors the weight a defendant contends they deserve renders the sentence unreasonable”).

For the foregoing reasons, we affirm.
