Meet the people who make Summit Pediatrics amazing

Our Providers

  • Christina Raman, MD, FAAP

    Dr. Raman grew up in Reno, moved around a bit for high school and college, and then came back home for medical school at the University of Nevada. She did her Pediatric residency at University of Utah in Salt Lake City and spent a couple of extra years there working in the Pediatric Emergency Room for good measure. She joined our practice in 2014 after moving home again for good, and took over as practice owner in 2021. She loves getting to be a part of her patients’ lives as they grow up (even if they all hate her at their 15 month check-up).

    When she’s not working, she loves to run, ski and chase after her two adorable but extremely loud children (who are incidentally also the reason she needs to run and ski sometimes).

  • Cassandra Ceremuga, DO, FAAP

    Dr. Ceremuga grew up in western South Dakota, attended medical school in Denver, and completed her Pediatrics residency at University of Nebraska. She’s excited to be moving back west closer to her family, and looks forward to enjoying our mountains with her lab Bella.

  • Vidya Kailash, PA-C, MPAS, MPH

    Vidya grew up in Carson City and has lived in the Reno/Sparks area for most of her life. She received her Masters degree in Physician Assistant Studies in 2012 from Touro University Nevada in Henderson. She also has her Masters in Public Health and Bachelors in Biology from the University of Nevada, Reno. Vidya joined Summit Pediatrics in 2013 and really enjoys interacting with children of all ages and their families, especially all the high fives and hugs!

    In her spare time, she enjoys spending time with her family and friends, traveling all over the place, visiting aquariums and zoos, reading anything she can get her hands on, watching movies involving superheros and animated talking animals, and trying different cuisines. She’s very excited and honored to be a part of our patients’ childhood experience!

Our Administrative Team

  • Cathy Olsen

    Cathy is our office manager. She keeps all of us in check. Cathy has been with Summit Pediatrics pretty much since Dr. Mathew started practicing in Reno. Yes, that long! She is the one to ask for if you have any billing/insurance questions.

    Outside of the office, Cathy enjoys spending time with her family, camping in the pines, long walks on the beach, and relaxing with a good book whether it is in front of the fireplace or swinging in the hammock under the shade.

    Heather is the newest member of the Summit Pediatrics team, and we’re so happy to have her! More info to come =)

  • It all started with Dr. Mathew.

    Summit Pediatrics owes everything to Dr. Shaji Mathew, who created this place from scratch with his own hard work. He founded Summit Pediatrics in 2006 and brought together this amazing team. The world lost Dr. Mathew in 2020, and we miss him every day. He was so proud of this place.
