A New Kind of Health

Latest News

More News for SFP!

May 7, 2019


Boy, times sure are changing at SFP!   We are sad to announce that Dr. Zapp will be leaving Sterling Family Practice as of June 23rd to start her own practice which has been a dream of hers for quite some time.  She, as many of us, have been frustrated with the insurance game and the inability to spend adequate time with patients to try to really make a difference in their health.  Her new practice is called Destination Health.  Look up her website for more information.   We wish her the best of luck on her new venture!


So while in the last several months two of our practitioners as so many practitioners seem to be doing these days, have decided to ditch the insurance game, Dr. Fletcher, Cynthia Yew, NP and Nazee Nassiry, NP will continue to try to make a difference in the lives of our patients  and working with insurance.


Insurance companies have made it increasingly difficult to treat patients outside of the conventional medicine model.  Not paying for important labs used for diagnostic purposes in functional medicine and not paying for various therapies that have proven to be very effective in treating patients such as functional medicine nutrition services, Heart Math biofeedback training, ozone, and visceral and osteopathic manipulation to name a few has proven to be very frustrating for providers trying to get to the root cause of poor heath and get people healthy again.


Dr. Fletcher, Cynthia Yew, and Nazee Nassiry are committed to providing excellent health care and helping people who have already payed their insurance premiums and may not have the extra money to pay for functional medicine services outside of their insurance coverage.  We will continue to take and bill insurance companies.



If you have any questions or concerns, please call the front desk for more information.


Thank you and God Bless,

Dr. Sarah Fletcher

Cynthia Yew, FNP-BC

Nazaneen Nassiry, FNP-BC

Exciting changes happening at SFP for 2019!


Congratulations to Cynthia Yew, NP for becoming the latest of our providers to become a certified Functional Medicine Provider through the Institute of Functional Medicine!   With the start of the new year, there are several announcements we need to share!


Provider Updates

It is with mixed feelings that we announce that Jessica Scalzo has taken a new job with The Virginia Center for Health and Wellness.  Although we will miss her dearly, we are excited for her new journey

she is about to embark.  Dr. Fletcher, Dr. Zapp, and Nurse Practitioner Cynthia Yew are excited to meet and take over care for Jessica’s existing Functional Medicine patients.  Nurse Practitioner Nazee Nassiry is also available to care for those not needing a functional medicine approach.


Dr. Fletcher will now return to the insurance world and begin seeing patients under insurance.  She will not be able to see Medicare patients until next year when her contract with Medicare is reinstated.     Dr. Fletcher is Board Certified in Family Medicine and Integrative Medicine.  She will continue to offer her manual therapy under insurance coverage and her alternative therapies on a cash basis.



Our ability to do tele-visits is now available!  These visits are helpful in reviewing test results and for acute visits where a detailed physical exam is not needed.  We are able to bill your insurance company for these visits based on the time spent in the visit.  Please call the front desk for more details and available appointments.


IV Services

With cold and flu season among us, we want to remind you that Caitlin in our IV center is ready and available to give IV infusions of Vitamin C, Myers' Cocktails, Ozone, and UV Light  among other things to keep you healthy through the season.
