  • Marissa Jan
    Office Manager/Dental Assistant

    I have been in dentistry for twent plus years. I love meeting new patients and love developing the relationships that I have built over the years with our current patients .The other part of my life other than dentistry is my wonderful family. I am a wife to my husband Nathan and my high school sweetheart. I am also a mother of two our daughter Alexis and our son Tayton. Alexis is a Texas A&M student to be an Animal Science Major. Specializing in Equine.  Our Son Tayton shows animals also loves to hunt and fish. As a family we love to hunt and fish together, and we all love the outdoors as much as we can.

  • Megan Manville R.D.H.

    I have been in dentistry for 8 years now and came to work for Dr. Arellano in March 2017 shortly after he opened the new office in Rosenberg. I graduated from Wharton County Junior College Dental Hygiene Program in 2010. One of the things I enjoy most about my job is the relationships I make with my patients. When I am not working, my husband and I enjoy spending time outdoors and every year we take a road trip to a different state to enjoy the views. We have a miniature dachshund who is the center of our attention as well as nieces and nephews who we love watching grow. We both grew up in Needville and plan on keeping our roots here with our family.
