I went to three doctors before Dr Trenkle because I had a sore on my face, that wouldn't heal. They all told me it would heal, not to worry about it. But it didn't heal, so I went to see Dr Trenkle and she asked some questions and took a biopsy. So blessed she did, because I had skin cancer and the other doctors were clueless. I continue to see Dr Trenkle because I trust her, she knows her stuff.

She's a great doctor but the wait times are not something you want to experience. They schedule multiple appointments at the same time and have you wait 45-50 mins. If you have time for that I say go for it else look for another doctor.

She is so nice and doesn't try to upsale you on anything. If she thinks you don't need something, she'll just say, No, I don't think you need that. I have filler and botox from her and have for years. She is also very very very good at being able to give you a liquid facelift and has a keen eye. Her staff is also very considerate.

I was so amazed with Dr. Trenkle. She was so kind and thorough. She took her time and explained what she was doing and my treatment plan. After my appointment, I came home immediately and called my family to tell them what a great experience I had and that they should contact her for their dermatology needs.
