Patient Testimonial
Dr. Libby was just amazing. We had a long journey and she was right there with us in the trenches. She was our third fertility doctor. She thought outside the box, was willing to try new things, was open to our questions, and used her team to help us.

I went through IVF with Dr. Humm. I felt heard, comforted, and comfortable the whole way. The support staff were beyond fantastic and turned what would have been a scary experience, into something that my husband and I never felt like we were navigating alone.

Dr. Libby listened to our every concern and communicated with us when we needed it, never making us feel pushed to the side or that she was to busy to be there for us.

From the first consultation until our final appointment Dr. Doyle was empathetic, compassionate, and very easy to talk to. He reviewed my diagnosis and treatments each step of the way and changed our protocols accordingly to result in a positive and viable pregnancy.

I had an ultrasound and an HSG done at the Norfolk office. Every staff member was amazing – so gentle, comforting and supportive. I’m very grateful for that.

Dr. Banks is attentive, kind, and professional. She answered all of our questions.

Q&A

As a resident, I met several role models who helped further spark my interest in the field of reproductive endocrinology. It became clear to me that helping people create or expand their families was one of the most rewarding things I could possibly do with my life.

Reproduction is the most significant process that we do as humans. If reproduction does not work, that is the end of our species!

 I feel that it’s most important to cultivate and maintain the understanding that I am a member of my patients’ team. I am on their side. There can be so much unbearable frustration involved in prolonged fertility treatment, and I feel it is important for me not to look away and to make sure my patients know I am with them for the duration of the journey, no matter the outcome.

As a child, I was obsessed with Marie Curie and read her biography over and over. I usually never read a book twice!

Scuba diving, hiking, and cooking.

I love nature and hiking in Colorado is one of the best ways to enjoy it. Scuba diving is like hiking but underwater – it offers same feeling but with more equipment! Also, who doesn’t love eating a delicious and beautifully presented meal with friends and family?

I’m a sunny optimist for sure.
