Operations Specialist
Dental Assistant
Hi, I’m Melissa Portillo, and I’m so happy to be part of the Thornton Dental family!
I’ve been in the dental field for over 20 years, and throughout my career, I’ve learned that dentistry is about so much more than teeth. It’s about people, relationships, trust, and making every patient feel comfortable and cared for. I truly love getting to know our patients and being part of their journey toward a healthier, more confident smile.
Outside of the office, family is everything to me. I’m a proud mom of three amazing children and an even prouder grandmother to five wonderful grandchildren. I’m also blessed with an amazing husband who is my partner in life and my biggest supporter. And, of course, I can’t forget my fur baby, Maggie May, who is very much a member of the family!
Fun fact about me: I have an identical twin sister! Having a twin has made for a lifetime of memories, laughs, and a few stories that I’m sure she would tell very differently. 
After 20 years in dentistry, my passion for helping people hasn’t changed. I’m grateful to be part of a team that genuinely cares about our patients and strives to make every visit a positive experience. I look forward to welcoming you to Thornton Dental and getting to know you and your family!
Dental Assistant
Hello! I’m Michaela, one of the Dental Assistants here at Thornton Dental.
I’ve lived in a lot of places, but no matter where I’ve been, I’ve always loved helping people feel cared for. That’s why I’m so proud to be part of a team that focuses on making each patient feel relaxed, heard, and confident in their smile. As the oldest of five siblings, I’ve learned to stay calm, multitask, and bring a gentle approach to everything I do.
Outside the office, I love spending time outdoors with my family, especially fishing trips on the boat. I also enjoy experimenting in the kitchen, planning new travel adventures, and relaxing at home with my two cats, Bourbon and Mr. Kitty; who always keeps life interesting.
I hope to make your visit to Thornton Dental not just comfortable, but something you leave feeling better from, inside and out.
Social Media Coordinator
Hi, I’m Karen Thornton, the Social Media Coordinator here at Thornton Dental. My husband and I met in Bryan-College Station and, after 40 years away, we recently returned to retire and reconnect with this wonderful community where we both graduated from Texas A&M. I’m a retired educator who remains passionate about advocating for education and educators, and I’ve had the honor of serving on several community boards.
In retirement, I’ve embraced new roles—one of my favorites is managing social media for Thornton Dental. From the moment you walk through the doors, you’re welcomed by the warmth of the staff, a calming atmosphere, and the confident, reassuring presence of Dr. Rahimi-Thornton (Dr. RT)
What makes this role even more special to me is that Dr. RT is also my daughter-in-law. I’m incredibly proud that she is married to my son and even prouder of the compassionate, skilled care she provides to every patient who walks through our doors.
Since moving back to BCS, we’ve loved spending time with our grandchildren, reconnecting with friends and family, traveling, and continuing to support Texas Aggie football, Blinn College Foundation events, and Texas A&M alumni activities.
Thornton Dental is more than just a dental office—it’s a place that truly cares for the whole person. I’m honored to be part of a team that serves our community with heart and integrity.
