  • “The first time I met Dr. Callen was for a 1st trimester ultrasound where she informed me I had MC. She was kind, professional, and accommodating to next steps. I believe due to Dr. Callen's competence and kindness, I have a beautiful baby girl today. She wasted no time in getting us on a path to a healthy pregnancy. The best of the best!”

  • “I saw Ramona Rule today for the first time as a new patient. The whole process is so easy at GG OBGYN. Ramona was patient, kind, understanding, and knowledgeable. I am so glad my friends referred me to this office and so glad I found a doctor I am so comfortable with.”

    —Haley B.
  • “The office itself is busy, modern, and clean. The staff is very polite, friendly, and organized. They are always on top of my medical care and next steps. When papers needed to be signed and approvals made, Cynthia and Judy were in constant contact with me, and they both went out of their way to help me. Make an appt and see for yourself!”
