Meet Our Doctors & Staff

Dr. Merlin Koshy

After completing her Bachelor of Dental Surgery, Dr. Merlin Koshy moved to the USA more than a decade ago to make Mesquite, TX her home. She joined her husband and decided to move to California where her husband worked. There she shadowed a local dentist, which motivated her to further her career.

Her hard work paid off as she was selected to the DDS program at University at Buffalo(SUNY), New York. Dr. Koshy gained tremendous experience through her voluntary experience in various organizations like RAM(Remote Area Medical), and including a dental mission trip to Dakar, Senegal while she was in dental school. After completing her degree she decided to move back to Mesquite, TX where she joined her family. Ever since she has been practicing in the DFW area and is excited to open her own practice in Sunnyvale, TX, and provide patient-focused dental care in Sunnyvale/Mesquite area. Dr. Koshy strives to keep herself updated with the latest technology in dentistry and has equipped herself with state-of-the-art equipment to serve your dental needs. If you are looking for an honest, hardworking dentist who treats you like family, just stop by her office to meet your new family dentist.

When she is not in the office, she loves to spend time with her family. She loves to play with her 3-year-old son and 3-month old daughter. She likes to travel with her family and enjoys trying out different cuisines.


Meet Our Team



Dental Assistant

I was born in Dallas, Texas. I couldn’t see myself ever moving out of the great state of Texas! I have a 4-year-old daughter named Elena. We love to karaoke in the car with the music up loud, playing with her Barbies, and watching movies. As a mother of a little one when I have any free time I enjoy crafting and sitting on the patio soaking up some sun. 

I started my dental career after graduating high school learning hands-on. I became a registered dental assistant in February 2012, coming up on nine years and I still have the same passion and love for what I do every day. From getting the rooms set up to creating relationships with patients and everything in between.
