Two Passionate Doctors Serving Chandler Together

Portrait of Dr. Matheson.

Dr. Alexander Matheson

Dr. Matheson is an Arizona native and a proud Chandler High School alumni. After high school he graduated from the University of Arizona and then Oregon Health and Sciences University’s School of Dentistry where he received his Doctorate in Dental Medicine.  His interest in dental implants during school led him to pursue an Advanced Education residency at the UCLA School of Dentistry where he spent an additional year learning from top mentors and honing his implant and cosmetic dentistry skills.

Continually sharpening his skills through world-class educational opportunities and sharing what he has learned with others are top priorities for Dr. Matheson. He is a featured speaker at study clubs and dental implant continuing education events across the country and enjoys mentoring current and future dentists.

Dr. Matheson believes in giving back and currently volunteers in his community as a Planning and Zoning commissioner. He is also passionate about reaching out to underserved populations and donates time at dental clinics for refugees and other groups.

Dr. Matheson’s interests include family, church, swimming, biking, and University of Arizona sports. He’s also taking guitar lessons in preparation for that garage band he plans to start one day. He and his wife are the proud parents of seven children.

Dr. Samantha Holder

Born and raised in the south suburbs of Chicago, Dr. Samantha Holder was “smile-crazy” from an early age and knew she wanted to be a dentist. She loves the way she gets to know people through dentistry and how gratifying it can be to change someone’s life for the better through a restored smile or relief from pain.

Dr. Holder attended Illinois State University and graduated with a bachelor’s degree in Clinical Laboratory Science. She continued her education at the University of Illinois at Chicago, where she completed her Doctor of Dental Surgery degree in 2006. While at UIC, she received the Gerald L. Wine scholarship for excellence in patient relationships.

Dr. Holder continues to show her commitment to patients by focusing only on them and spending the extra time to ensure that their comfort and dental needs are fulfilled. Each of her patients is treated like family! She is passionate about your comfort, convenience, and personally ensures you get the best results.
