Broxton Davis – Clinical Pharmacist

"Great employees, nice, clean environment. Love it when they find ways to help those with low or no income. Every little bit helps so much and they sometimes have contests or promotions to help you help yourself. I am entered to win a Kindle because I had a PAP done. How awesome is that?"


"My doctor is wonderful. He takes his time and I never feel rushed. I am always in the room on time and out within a reasonable time."

"First time and I was absolutely impressed. Had a dental emergency and no insurance. HealthLinc went above and beyond my expectations. Ended up having 5 teeth pulled that have been bothering me for years. No other dentist would even touch them because I had no dental insurance. I can honestly say I was very impressed and thankful to finally have decent care at a decent price."


"I love HealthLinc! Service is always fast and friendly. Nurses and doctors are wonderful! I refer HealthLinc to all my friends!"


"Comfortable atmosphere, sliding scale payments with good physicians that care. They truly care about the patients and go above and beyond to help. I went to HealthLinc before having insurance, but still go here now that I do because I enjoy them that much. I would recommend to anyone seeking general medical help."


"I have had nothing but caring doctors and dentist here for my child. On her first dentist apt. they were very understanding and patient with my child who was afraid and comforted her very well. The doctor was amazing and I'm happy she's my daughter's new family physician."


"When we lost our health insurance I panicked, but a HealthLinc Navigator was there to help. She held my hand through the entire process and made sure I was taken care of. In a time of such uncertainty, she made me feel confident that we would be OK. "
