    "I avoided the dentist for years because of anxiety, but Dr. Mackey completely changed that. She explained every step, never rushed me, and for the first time in my life, I actually felt calm in the dental chair."

    -Kaitlyn M

  • A woman with dark hair smiling at a dining table outdoors during evening or night.

    "Dr. Mackey explains everything in plain English and makes sure I understand the 'why' behind her recommendations. I never felt pressured - just informed. It's refreshing to have a dentist who treats you like a partner in your care."

    Tina M.

  • A smiling older man with gray hair and glasses sitting on a green couch in a cozy living room with bookshelves in the background.

    "Dr. Mackey identified signs of sleep apnea during a routine exam and worked with my doctor to get me treatment. The custom oral appliance she made has been life-changing - I'm finally sleeping through the night."

  • Headshot of a man with glasses, smiling in an indoor setting.

    "My 5-year-old was terrified for his first dental visit, but Dr. Mackey was amazing with him. She was patient, gentle, and made it fun - even let him hold the 'tooth counter' mirror. He left excited to come back, which I never thought I'd see!"
