Patient Testimonial
I would highly, highly recommend Dr. O’Hern! Throughout my struggles with infertility, she has been kind, supportive, thoughtful, and determined to help me achieve a pregnancy. The staff at SGF, both in Clear Lake and the Medical Center, are amazing to work with!

Working with Dr. Kallen and his entire team was an absolute pleasure. They took time in designing a medical plan specific to our situation. Dr. Kallen never gave up on us and constantly reassured us at every step of the way to a successful pregnancy! We are very grateful for Dr. Kallen the SGF team!

Dr. Healy is so kind and selfless she is one of the kindest people that I’ve ever met. I definitely recommend her for any fertility treatments that people may need. We would never choose anyone else to handle our care. If you were looking for a fertility doctor, she is, hands-down, the best.

Dr. Mitchell and her team are dedicated to their patients in their journey to getting pregnant. She is so kind and always makes sure you are comfortable and understand what’s going on and next steps. She communicates so well with her team and patients and I cannot be more happy with my experience.

10 out of 10 recommend! From the first day we stepped foot in Dr. Shah’s office we could feel the amount of love and care him and his team give to their patients. Our fertility journey wasn’t easy but this clinic went above and beyond to make sure it was successful.

I switched to SGF because of our first visit with Dr. Shah. He has great bedside manner, clear communication, manages expectations, and has a great staff. He is very proactive with your healthcare and makes you feel cared for.
