From supplements to surgery, birth control to menopause, if you have serious concerns or just need an annual checkup, you deserve personal attention designed specifically to meet your needs. At Optimal Health Associates, we are very comfortable discussing intimate and personal issues with our patients.

We bring this same sensitivity and empathy to our approach with men. Whether fatigue, weight gain, erectile dysfunction, loss of sex drive or some combination of these or other symptoms, our team can help. Vaginal dryness, burning and being constantly bothered are a result of atrophic vaginitis, which is often not spoken about because some consider it a natural consequence during menopause and after childbirth.
Services
Together, we strive to earn patient trust as the most progressive, collaborative and comprehensive specialty healthcare team in the country. Our patients understand, as we do, what matters most: unrivaled compassion, a personal connection and a kind explanation as we deliver comprehensive, complex and compassionate care.
Urogynecology is a fairly new subspecialty that focuses on disorders of the female pelvic floor. Pelvic floor disorders can be the result of weakened or damaged pelvic floor muscles secondary to childbirth, obesity, surgery, chronic disease, or heavy lifting. Dr. Barenberg sees women affected by pelvic floor disorders such as urinary incontinence and pelvic organ prolapse.
Comprehensive, complex and compassionate healthcare for women - that's the Optimal Health approach and exactly what you deserve. From supplements to surgery, birth control to menopause, if you have serious concerns or just need an annual checkup, you deserve personal attention designed specifically to meet your needs.
Whether you seek routine care or a new approach to a serious issue, we're here to answer all your questions in a way you understand. We know choosing gynecological care is a very personal choice. It can be simple and routine. It can also be very complex. We strive to provide the very latest information.
With more than 30yrs combined experience, we can assure you that you will receive exceptional compassionate care. Dr. Williams is a specialist in true minimal invasive approaches to complex gynecologic surgical diseases. As an expert laparoscopist, over 99% of his hysterectomies and abdominal cases are completed without exploratory surgery.

Love this place. As a physician myself I appreciated a lot of things. The clinic was a well oiled machine, didn’t wait long for anything, all was in order, And I loved dr Williams and his NP. Finally someone who validates my symptoms post vaccine and actually has a plan to treat me, unlike the five doctors seen previous. If you’ve got something unusual going on, I feel like Dr Williams rises to the occasion and thrives on challenges. He combines both traditional and natural medicine and is not intimidated by going against the grain/popular opinion. This clinic thinks outside the box.

Terrible experience. Long waits, not a friendly or helpful staff member in the facility, and nothing gained from the appointment. I had blood work in October that it's January and I have yet to receive the results for, but you better believe they are mailing me weekly for their $25 that insurance didn't cover. You call and are never able to talk to a human, you then have to fill out a request online that never gets acknowledged. Not surprising though because I filled out my new patient paperwork beforehand online and they couldn't find it, never received it, and said their website is notorious

Went for a 10:00am appointment, I'm diabetic, sat in the exam room more than 40 minutes, got up and walked out. The PA hasn't done anything for me that I couldn't do for mysel. My PCP can write Rx's for insulin, I can adjust the dosage, been doing it for 9 years. Why should I pay $45 copay for a "specialist "?

Can i just say that dr barnberg and his staff is amazing! I have been struggling to find a decent dr and one who would listen and get me the right meds. It took them 1 day to work with my insurance to get my meds where other drs told me they couldn't work anything out or just wouldnt do it.

I have been going to Abby Ronck for the past 3 years. I have always felt so incredibly comfortable and with her help we were able to find out answers to issues I was having and form a treatment plan. I have also been in to see other doctors when Abby has been unavailable and they have been fantastic as well. All of the staff has been super kind to me every visit. I highly recommend Optimal Health especially for teens who are a bit nervous about their first “lady doctor” (lol) experience!!

I went to see a doctor from Optimal Health because of a pituitary tumor. 1st - The doctor I saw was 45 minutes late and probably would’ve been even more late if I hadn’t left my room and asked some assistants who were just standing around talking and laughing. 2nd - The doctor didn’t have any of my medical records. Not the lab work, Ct scan of my head, MRI of my brain or the MRI of my pituitary. 3rd - They did lab work again. This is understandable and I’ve been through hell and back when it comes to medical stuff so I know that drawing my blood should not take over 2 minutes. The tech

Dr Noel Williams and the entire staff here go above and beyond for their patients. From the front desk staff, to the PAs, they're a well oiled machine and they're very well trained and beyond professional. I was blown away at my first visit. They sit down face to face and do what most drs offices these days dont do... they LISTEN!! Truly and genuinely listen to you. I highly recommend this place to anyone. I have been passed around from dr to dr for years with unexplained chronic symptoms and Optimal Health has given me hope for the first time in years.

Called to set up a new Patient Appointment and it was extremely easy. Although the Doctor was booked up for several weeks, I was fit into one of the PA's schedule relatively easy. I was able to meet with Trisha whom was SPECTACULAR. Extremely intelligent so I instantly knew I was in great hands. Every single person I dealt with was friendly and extremely professional. The office itself is very nice and the waiting room has a comfortable environment. I wanted to get a new birth control method and they were knowledgeable and told me about each different option they offered and allowed me to make
