Meet Dr. Tim

Timothy J. Leishman, DMD

Dr. Timothy Leishman was raised in a small town in northern Utah, where the close-knit community helped shape his values and his compassionate approach to patient care. He earned a Bachelor of Science in Exercise Science from Brigham Young University, where his studies in anatomy and physiology inspired him to pursue a career in healthcare.


During his undergraduate studies, Dr. Leishman took a two-year leave to serve as a missionary in southern Mexico for The Church of Jesus Christ of Latter-day Saints. Through this experience, he became fluent in Spanish and developed a deep appreciation for different cultures, meaningful connections, and service to others.


Dr. Leishman earned his dental degree from the Arizona School of Dentistry & Oral Health in Mesa, Arizona. He then completed advanced specialty training in dental anesthesiology through a residency at NYU Langone in Brooklyn, New York. As a board-certified dental anesthesiologist, he is committed to providing exceptional care through clinical precision and a calm, safety-focused approach that prioritizes each patient’s comfort and well-being.


Dr. Leishman and his wife, Lexie, are proud to call Texas home, where they are raising their family. They value the strong sense of community and exceptional quality of life that the Lone Star State offers.

“Just doing a shout out for Dr Tim, he provided my son with such wonderful care and even checked on us the day after his surgery to make sure that my son was doing okay! He was extremely kind and talked about what he would be doing for the procedure and gave me clear instructions on everything I needed to do as well in order to make this as painless/traumatizing for my son who has special needs. Thanks again dr tim!”

“Hello, My review is for Dr. Tim, (Timothy J. Leishman ) the anesthesiologist who attended to my son during his dental procedure with great efficiency, patience, and empathy. He is undoubtedly one of the few doctors who takes the time to address every concern—doubts that we, as parents, inevitably have when our children face a procedure involving anesthesia. I felt very calm and confident knowing that my son was in Dr. Tim’s care; I am grateful that there are still doctors who possess such a true gift for service and empathy toward both their patients and the parents.”

“We’ve been working with Dr Tim for about a year and a half and have nothing but good things to say about him. When I made the decision to bring general anesthesia into my office, I wanted to make sure we partnered with an anesthesiologist that prioritized the safety and well-being of our patients over everything else. Dr Tim is deeply knowledgeable, wonderful with children and has the smoothest wake ups from anesthesia of any anesthesiologist I’ve ever worked with. He is a fantastic asset to our patients and we are so pleased to have him as part of our team..”

Got Questions?
We've Got Answers!

Why might a child need general anesthesia for dental treatment?
Some dental procedures are lengthy or complex. General anesthesia may help a child receive needed treatment when age, anxiety, difficulty staying still, or an individual medical or developmental need makes treatment while awake difficult or unsafe. It allows the dentist to complete the planned care while the child is asleep.
Is general anesthesia safe for children?
General anesthesia has risks, but careful planning and monitoring help reduce them. Before the appointment, the dental anesthesiologist reviews your child’s medical history develops a plan based on their needs. The anesthesiologist monitors your child continuously during the procedure and through recovery.
Who provides the general anesthesia?
A licensed dental anesthesiologist administers and monitors the general anesthesia. During the dental procedure, the anesthesiologist focuses on your child’s anesthesia care safety.
Will my child be asleep during the entire dental procedure?
Yes. Your child will be asleep during the entire dental treatment. Awareness during a procedure is rare and unlikely.
How should I prepare my child before the appointment?
You will receive instructions about when your child must stop eating and drinking. Follow them carefully, including any directions about water and routine medications. If anything is unclear, contact the office before the appointment. Eating or drinking outside the permitted times may require the procedure to be delayed or rescheduled.
How will my child be put to sleep?
In most cases, your child will breathe anesthetic gas through a face mask to fall asleep. If the mask is not suitable or your child cannot tolerate it, the anesthesiologist may recommend an injection of anesthetic medication into a muscle. Once your child is asleep, an IV will be placed. Anesthesia will then be maintained with inhaled, IV medications, or both. The anesthesiologist will explain the plan and answer your questions before the procedure.
