About us

On-Site Medical Care, A Direct Primary Care Practice

I have been seeing the team here for about 6 months and they are great! They are super flexible with appointments and always reach out checking to see if I have any questions or need anything updated. The pricing is also highly competitive to others doing the same if not less! I love it! Thank You!

My experience with the staff at On Site Medical has been wonderful. The staff has been very communicative and helpful and Jen is fantastic! Everything is easy and affordable- truly everything I need in a medical provider. I’m very optimistic and excited to start my care here. Thank you Jen, Nay, and Carla!

With the help of Jenn and her team, I’m on the path to happier and healthier future. I’ve never been a big doctor visit guy but I’ve learned more about my overall health in the short time of dealing with On-Site than I have my entire life. Do yourself a favor and embrace the change that this team can help you achieve! They are always available for support and ready to answer any questions you may have along the way. I’ve sent text or called Kari several times and ALWAYS get a quick response when really not expecting it so soon. Kari sends out updates on my request and lets me know when I can be expecting my deliveries right up until they are in my mailbox. Amazing team of people that truly make you feel as though you’re the only one they are working for when I know that’s not the case. I know because my wife is now a patient as well! Being new grandparents, we are making changes and embracing the process to be able to keep up with our grandkids for years to come! Many thanks to Jenn, Kari, and the entire team!

Leaving “standard insurance” and using this service has been the best decision. Reduced my cost exponentially and receiving way better care. They are always available (for visits/care and scrip refills), communicate quickly and clearly, and have been very fantastic in helping me resolve a medical issue. I am extremely pleased to have made this switch.

I had a great experience with OnSite Medical Care and highly recommend them. The atmosphere was warm and welcoming, and the staff was incredibly friendly, professional, and attentive. Jenn, my provider, took the time to listen and explain everything thoroughly and even created an EXTREMELY detailed and well-thought-out care plan that made me feel confident and cared for. After speaking with Carla, the Director of Culture and Care, I knew I was in good hands and on the right path to a healthier lifestyle. Truly top-notch service all around—I can’t thank them enough!

I want to be very clear: Dr. Jen Hawkins herself is knowledgeable and capable. I was a patient with this clinic for over a year following a full hysterectomy, and Dr. Jen initially helped me achieve better hormonal balance during a very difficult time. My concern is not about her medical knowledge or intent.

My concern is with how this clinic communicates with patients and how patient concerns are handled—particularly through text messaging.

Recently, I became increasingly unwell and began experiencing significant symptoms consistent with hormone imbalance, including chest pain, nausea, sweating, brain fog, emotional numbness, joint and bone pain, hair thinning and breakage, acne, water retention, and overall decline in well-being. At one point, I seriously considered going to the ER. I reached out to explain what I was feeling, clearly stating that I am not a medical professional, only sharing observations and asking to speak in person with my physician.

Instead, my messages were interpreted as me “telling the doctor how to do her job.” That was never my intention. I repeatedly requested an in-person appointment because text is not an appropriate medium for nuanced hormone management. I was scheduled for January 8th.

Then, without warning, I woke up, (Dec. 31), to a message stating that my membership and care had been canceled entirely.

When I called for clarification, I was told that “staff felt uncomfortable” and that there had been “incidents over the last year,” yet no specific examples could be provided. I have never had a single issue with staff in person and have always been respectful and cooperative. Ultimately, the explanation centered around how my texts were perceived.

During that call, I offered feedback that if staff were concerned about the tone or content of my messages, it would have been far more appropriate to call me directly and ask how I was feeling, especially given my symptoms. I also stated that if I had actually spoken negatively about Dr. Jen or questioned her competence, that would have been an appropriate time to address or even end the relationship. I was told in response, “We are a private business and we can add or remove people as we see fit.”

Given the timing, I raised concerns about whether external factors or miscommunication may have contributed to the decision. I was told this was not the case. I am documenting this interaction because the sudden termination of hormone care significantly impacted my physical and mental health and left me without adequate transition or support.

Canceling a patient’s hormone care based on perceived tone in text messages is deeply concerning. Hormonal therapy directly impacts physical and mental health, and abruptly terminating care without transition, clear explanation, or support places patients at risk.

I also shared concerns that text-only communication creates misunderstandings and leaves patients feeling unsupported during vulnerable health situations. I was told this was “probably a miscommunication,” yet the cancellation of care remained unchanged.

I believed in Dr. Jen’s work and referred multiple paying patients to this clinic. I did not expect to be dismissed, mischaracterized, and dropped during a health crisis.

This clinic needs to seriously reevaluate:
-Its reliance on text messaging for complex medical care
-How patient advocacy is interpreted
-It's  process for ethically terminating care
-How patients experiencing acute symptoms are supported

Patients deserve clear communication, professionalism, and continuity of care-especially when dealing with hormone health.
