Meet The Staff


Marie Ryan

I enjoy my position as the Office Manager and nurse for Dr. Leveno. I started here February 2013 and from the first day felt as if I was part of a family. Dr. Leveno’s caring and compassion for his patients is very rewarding to work with.

I have been in the medical field for over 30 years, I love getting to know and working with the patients. I am married to a wonderful husband Doug and we are blessed with two children, Emily and Hunter. Last year, we welcomed our first grandson, Ryder Blaze and he has truly stolen my heart. We moved to Texas over 20 years ago from Illinois. I enjoy time with my family and being active in my church.

I am always available to our patients with any questions or concerns they may have about the practice.

Donna Ryan

I started working with Dr. Leveno in 2009. I have enjoyed providing prenatal care and welcoming “little bundles of joy” to his OB practice. It is also my pleasure to assist Dr. Leveno in providing quality and compassionate care to women of all ages. Due to the retirement of Dr. Bender whom I worked with for several years, I was privileged to help with his patients’ transition of care to Dr. Leveno to be as comfortable as possible. Since I have medically served some of these patients for 12 years and regard them as family and friends.

I have over 40 years’ experience as an LVN in physician’s offices. I have worked both OB/GYN and preventative care.
