About Our Doctors


Janice Weinman, D.D.S.

Dr. Janice Vlasak Weinman is a dentist in Seguin, Texas, who specializes in rendering caring, quality dental care to patients of all ages.

She opened her solo general and cosmetic dental practice in a beautiful, state-of-the-art facility in Seguin in July 2008. Prior to that, she practiced in Gonzales from 1989 to 2008 and in San Antonio in 1988. She earned her Bachelor of Science degree from Texas Lutheran College and her Doctorate of Dental Science from The University of Texas Health Science Center. Dr. Weinman enjoys all aspects of dentistry. She works closely with a TEAM of specialists for more complex cases that may require their assistance.

Dr. Weinman is married to Kevin Seider. After 35 years, God put this wonderful, caring man back into Dr. Weinman’s life, and the two quickly became great friends! God worked everything out so that Kevin was able to transfer his position with the Texas Department of Transportation to the Seguin office in November of 2015, the same month that the two were married! The couple especially enjoys spending time together hunting, which is Kevin’s passion.

Dr. Weinman is blessed with a beautiful daughter, Janelle Brooke, who graduated from Seguin High School in May 2014. She graduated from St. Olaf College in Northfield, Minnesota, in May 2018 with her Bachelor of Arts in biology and UT San Antonio in May 2019 with her Master of Science in business. Janelle is currently attending Marquette University School of Dentistry in Milwaukee, Wisconsin, pursuing her Doctor of Dental Surgery degree with plans to graduate in May 2023. Janelle decided to do her undergraduate and doctoral studies away from Seguin to gain a broader prospective of the world, as she hopes to one day return to Seguin as a dental professional.

Megan Stivers, D.D.S.


Hello, my name Megan Stivers, and I am excited to join the Seguin Smiles team. I was born and raised in Mansfield, TX. I attended Texas A&M University, followed by Texas A&M College of Dentistry in Dallas, TX. I married my high school sweetheart John, a Junior High teacher and coach. When we visited Seguin, we could instantly see ourselves living here and loved the close-knit community.

I grew up on the soccer field, and being active and outside is still one of my favorite things, whether going on a walk with our mini-Australian Sheppard Cody, sitting outside with friends, or working out. My favorite time of the year is fall because every weekend is spent watching Texas Aggie and Dallas Cowboys football.

I always loved science growing up and was drawn to dentistry because of the hands-on work and visual satisfaction it brings. I love that I get to develop long-term, meaningful relationships with my patients. If you see me around town, please say hello! I am new to the area and always open to new food or activity recommendations.
