Last I heard, he shared a practice with Massimo "Max" Testa (former 7-Eleven and Motorola team doctor).
Testa is also listed in the directory:
Massimo Testa MD (916) 734-6805 2825 J St Ste 400, Sacramento, CA 95816
Eric A Heiden MD (916) 734-6805 2825 J St Ste 400, Sacramento, CA 95816
And it appears as though he also shares a practice with his wife (?):
Karen D Heiden MD (916) 734-2700 4860 Y St # 3800, Sacramento, CA 95817
