Narrative:
During a normal departure from denver, co, to farmington, NM, we (my first officer and I) encountered moderate turbulence at the front range of the rocky mountains, while trying to maintain a comfortable ride for my passenger we deviated from our assigned altitude. This deviation was due to lack of attention on the part of both crew members and too much attention being paid to a comfortable ride instead of ATC instruction. Both my first officer and I discussed the incident after arriving in cruise flight and determined we would both be more vigilant from that time on. This occurrence served as a valuable learning tool. This was a perfect example of how CRM can prevent an occurrence.
