Changing Lives One Smile At A Time

Pueblo’s Own Dr. David Sisneros

Dr. David Sisneros was born and raised in Pueblo, Colorado. While he was growing up, his mother worked as a dental assistant, which gave him the opportunity to spend time at her dental office and witness firsthand the overwhelmingly positive impact that quality dentistry has on individuals and the community. This positivity stuck with him throughout his life, propelling him to a career in dentistry.

After graduating from Colorado State University, Pueblo with a Bachelor’s of Science in Biology, a Chemistry minor, and a Master’s in Business Administration, he traveled to the University of Minnesota School of Dentistry to receive his Doctorate in Dental Surgery. After a few years in Alamosa, he returned to his hometown to open his practice and provide quality dental care to the community where he grew up. 

Dr. Dave loves running Rocky Mountain Dental Co. with his wife, Alyssa. But when he’s not in the office, he enjoys spending time with his whole family and hiking the beautiful trails Colorado has to offer.

Patients love Dr. Dave!

Alyssa Sisneros

Registered Dental Hygienist

Alyssa has a passion for helping her patients feel confident about their smiles and has always had an interest in the dental field. For as long as she could remember she loved going to the dentist and picking her hygienist’s brain. 

After meeting Dr. Sisneros in college and discovering his passion for dentistry, she knew it was meant to be. Together they moved to Minneapolis where she attended and graduated from hygiene school in pursuit of a career in dental hygiene.
As a Pueblo native, Alyssa is excited to be back in the area to raise her family and provide care to the community where she grew up. Outside of work, she enjoys traveling, reality tv, being outdoors, and spending time with her family and friends.
