Lana Hickman, BSN, RN Practice Administrator

I had many patients that had been through fertility treatment when I was a Labor & Delivery nurse. I found it very interesting and wanted to look into helping fertility patients. I found Dr. Kristiansen and saw how much she enjoyed what she does. I knew that I would be great at it too. I've been with Dr. Kristiansen and the Houston Fertility Center for almost 19 years.

I enjoy guiding patients through their journey with education and support. I take great pride in my role in helping change a patient's life by starting or expanding their family.

I cherish quality time with my family watching movies and our exceptionally competitive game nights. I love to travel and have been to many beautiful places.

Valia Achille, PhD Embryologist
IVF Laboratory Manager

I always knew I wanted a career in the medical field that would allow me to make an impact in people's lives. After graduation, I started my career as an andrologist and then began working in the embryology lab as an embryologist. Embryology is a fascinating field that is constantly evolving and I'm lucky to be a part of such a life-changing science.

Working in the lab and being able to combine my love for science with life-changing work that helps patients start a family. There is nothing more rewarding that hearing that a patient is pregnant. I'm thankful to be a part of a great team that achieves that!

I enjoy spending time with my family and friends, taking care of all of our animals and traveling.

Katherine Billing Manager

I was interested in reproductive medicine because I wanted to be in a field where I can be a part of changing someone's life.

Assisting patients through the financial process of their journey through family building is what I enjoy most about my days in the office.  

Outside of the office I enjoy listening to music and spending quality time with my daughter.

Mayra, MA Lead Medical Assistant

I choose the fertility field because I thought it was very interesting to create life and give someone an opportunity to become a parent.

I enjoy being able to walk our patients through each step of the treatment with empathy. I love when patients tell us that we doing our part in making this journey easier for them. I like being part of their journey. It is an amazing feeling to know that the whole center played a part in creating their miracle baby and have made such a difference in someone's life.

Outside of work I love spending time with my family. I do enjoy being a parent even though there are struggles. We enjoy going to parks, walking trails and the zoo.

Blanca, MA Clinical Coordinator

I truly love helping people. I chose the field of fertility because I knew I would be great at helping people create a family.

I love hearing about our patients' success stories! Fertility is an emotional roller coaster for most patients and being able to finally tell a patient, "CONGRATS, you’re pregnant" is so fulfilling.

My hobbies are to be with my loved ones. I love socializing with my friends and family, watching TV (family movies and documentaries). I enjoy traveling, sight seeing, and learning the history of the places I visit. I am always ready to learn more.

Melissa, MA Front Office Coordinator

My passion has always been in the nursing field and what better way to fulfill that than to work in fertility where we can create life.

I enjoy seeing the faces of our patients when we give them the good news about being pregnant. I also enjoy making my coworkers laugh.

Outside of work I am a homebody so I'm typically at home enjoying time with my kids. I also like to go out and eat at different restaurants.

Nyosha Phlebotomist


I started working in the medical field because I have the desire to help people. When I’m not doing that I enjoy watching movies with my children. We’re all movie buffs. Binge watching movies and butterfinger milk shakes would be the perfect weekend!
