Envita Fertility Clinic Medical Staff

Together as our medical staff and as individuals, our people make the patient experience at Envita exceptional

Patients’ needs and comfort is at the heart of the way we have designed our medical and administrative services. In every step of a patient’s visit with Envita, we minimize delays and optimize streamlined delivery of care, from initial consult to each treatment appointment.

Our medical staff members are specialists in fertility medicine. Each one is focused on patient education and guidance so every patient feels confident and prepared in choosing the best path forward for them.

At Envita, everyone is a VIP – very important patient

And we have a thing for the small things: Each Envita patient gets a dedicated fertility coordinator, a patient’s personal care guide through every clinic detail, from the very first phone call to meeting your little miracle.

Our team approach to superb patient experiences – and success

At Envita Fertility Center, patients are not numbers to us, but future moms and dads. We get to know you and your concerns, preferences and goals. We know your story.

We understand that navigating fertility treatments can be overwhelming, which is why we provide concierge quality service. Each patient receives a patient coordinator who ensures that Envita always meets the concierge level of care. From the first phone call to the clinic, our patient coordinators serve as a personal guide.

Our fertility specialist, Dr. William Freije, oversees our patients’ care and the training of our medical staff. Lab Director Dr. Avisa Asemi manages all aspects of Envita’s important in-house in vitro fertilization (IVF) lab. Both are dedicated to excellent patient experiences, as are the medical staff members who follow.
